I added memory to a Windows XP Pro machine and concluded that the system was almost out of space! After investigating this problem found the installation in the folder windows file was more than 30 gig by itself, the files in this folder back to the initial installation of Windows.

You say that a "report" is 30 GB? Or a folder containing files?
Maybe overkill - but unless you have less than 1 GB of memory (live RAM) of the system, the upgrade of memory was probably exaggerated too with WIndows XP. ;-)
Search for malware:
Download, install, execute, update and perform analyses complete system with the two following applications:
Remove anything they find. Reboot when necessary. (You can uninstall one or both when finished.)
Search online with eSet Online Scanner.
The less you have to run all the time, most things you want to run will perform:
Use Autoruns to understand this all starts when your computer's / when you log in. Look for whatever it is you do not know usingGoogle (or ask here.) You can hopefully figure out if there are things from when your computer does (or connect) you don't not need and then configure them (through their own built-in mechanisms is the preferred method) so they do not - start using your resources without reason.
You can download and use Process Explorer to see exactly what is taking your time processor/CPU and memory. This can help you to identify applications that you might want to consider alternatives for and get rid of all together.
Do a house cleaning and the dust of this hard drive:
You can free up disk space (will also help get rid of the things that you do not use) through the following steps:
Windows XP should take between 4.5 and 9 GB * with * an Office suite, editing Photo software, alternative Internet browser (s), various Internet plugins and a host of other things installed.
If you are comfortable with the stability of your system, you can delete the uninstall of patches which has installed Windows XP...

How to use disk cleanup
You can disable hibernation if it is enabled and you do not...
When you Hibernate your computer, Windows saves the contents of the system memory in the hiberfil.sys file. As a result, the size of the hiberfil.sys file will always be equal to the amount of physical memory in your system. If you don't use the Hibernate feature and want to reclaim the space used by Windows for the hiberfil.sys file, perform the following steps:
-Start the Control Panel Power Options applet (go to start, settings, Control Panel, and then click Power Options).
-Select the Hibernate tab, uncheck "Activate the hibernation", and then click OK. Although you might think otherwise, selecting never under "Hibernate" option on the power management tab does not delete the hiberfil.sys file.
-Windows remove the "Hibernate" option on the power management tab and delete the hiberfil.sys file.
You can control the amount of space your system restore can use...
1. Click Start, right click my computer and then click Properties.
2. click on the System Restore tab.
3. highlight one of your readers (or C: If you only) and click on the button "settings".
4 change the percentage of disk space you want to allow... I suggest moving the slider until you have about 1 GB (1024 MB or close to that...)
5. click on OK. Then click OK again.
You can control the amount of space used may or may not temporary Internet files...
Empty the temporary Internet files and reduce the size, that it stores a size between 64 MB and 128 MB...
-Open a copy of Microsoft Internet Explorer.
-Select TOOLS - Internet Options.
-On the general tab in the section 'Temporary Internet files', follow these steps:
-Click on 'Delete the Cookies' (click OK)
-Click on "Settings" and change the "amount of disk space to use: ' something between 64 MB and 128 MB. (There may be many more now.)
-Click on 'Delete files', then select "Delete all offline content" (the box), and then click OK. (If you had a LOT, it can take 2 to 10 minutes or more).
-Once it's done, click OK, close Internet Explorer, open Internet Explorer.
You can use an application that scans your system for the log files and temporary files and use it to get rid of those who:
(just disk cleanup - do not play with the part of the registry for the moment)
Other ways to free up space...
Those who can help you discover visually where all space is used. Then, you can determine what to do.
After that - you want to check any physical errors and fix everything for efficient access"

Cleaning the components of update on your Windows XP computer
While probably not 100% necessary-, it is probably a good idea at this time to ensure that you continue to get the updates you need. This will help you ensure that your system update is ready to do it for you.
Download and run the MSRT tool manually:
(Ignore the details and download the tool to download and save to your desktop, run it.)
Download/install the latest program Windows installation (for your operating system):
(Windows XP 32-bit: WindowsXP-KB942288-v3 - x 86 .exe )
(Download and save it to your desktop, run it.)
Download the latest version of Windows Update (x 86) agent here:
... and save it to the root of your C:\ drive. After you register on theroot of the C:\ drive, follow these steps:
Close all Internet Explorer Windows and other applications.
AutoScan--> RUN and type:
--> Click OK.
(If asked, select 'Run'). --> Click on NEXT--> select 'I agree' and click NEXT--> where he completed the installation, click "Finish"...
Now reset your Windows with this FixIt components update (you * NOT * use the aggressive version):
How to reset the Windows Update components?
Now that your system is generally free of malicious software (assuming you have an AntiVirus application), you've cleaned the "additional applications" that could be running and picking up your precious memory and the processor, you have authorized out of valuable and makes disk space as there are no problems with the drive itself and your Windows Update components are updates and should work fine - it is only only one other thing youpouvez wish to make:
Get and install the hardware device last drivers for your system hardware/system manufacturers support and/or download web site.
If you want, come back and let us know a bit more information on your system - particularly the brand / model of the system, you have - and maybe someone here can guide you to the place s x of law to this end. This isn't 100% necessary - but I'd be willing to bet that you would gain some performance and features in making this part.

Original title: Windows 64-bit clean
Ive recently done my 2nd attempt to install windows 7 64 bit and ive met the same problem, I have formatted and deleted all the data ln my drive hard amd decided to do a clean install of windows, but when the disc it stops expanding windows files 0% I don't know why this is happening is the disc
You have all the features non-essential connected to the computer during installation? If you have external storage media connected, disconnect them.
It is also possible to reinstall your Windows 7 media is corrupt. You can try to download a new copy and try again.
I'm trying to upgrade to Windows 7 from Windows Vista SP2. The high-grade crashes at 21% of stage 3 (extension of files).
I did the following: uninstalled my Norton 360 Security software.
Chkdsk /r conducted and found no disk error.
A ran memory diagnosis, and he reported no problems.
Windows 7 Upgrade Advisor and uninstalled all the software and devices according to the guidelines. The system hung twice in the same place. I use a computer TechAdvance system with processors dual 2.66 GHZ on an Intel 965DH Mother board with 4 GB of memory and two hard drives. The boot hard drive has 76 GB of available disk space. A that someone has had this problem and solved?
I started this thread and wanted to complete what has occurred. With the help of Microsoft reps tech I was finally able to install windows 7 upgrade to windows vista. In the startup journal, Microsoft tech rep isolated oem drivers in my inf file in windows that don't migrate. We removed the oem drivers, after their record in a file on my desk just in case. We then went to msconfig and made a selective startup, turning off all non-microsoft services. We also had to rename the two files on windows put there by my first upgrade attempt, which failed, $UPGRADE ~ OS and $WINDOWS ~ BT by adding old to them so that the next upgrade attempt would not access. We started the new facility at 1730 m 31 October, finally the 0800 on November 1, the upgrade is complete. Now, I had almost half a million files and many programs on my computer that had to be collected and processed. The section of "Expanding Windows Files" step 3 remained on 21% after the first reboot of windows 7 during approximately 8 hours, suggesting he was hooked, but it was not, I let the system run all night, and voila, when I got up the next morning at 7:30 she had completed all five stages and was the starter in the new windows 7. It went fast, and from 08:00 it was running in windows 7 normally. In addition, my Norton 360 v 3.0 security system, which I had uninstalled for the upgrade to Windows 7, reinstalled with incredible speed. I was impressed and continued to test all the different programs and devices on my system and they work all well, and Windows 7 is faster than Windows Vista.
Even if it took 15 hours to install, I'm so happy with the results.

I have 64 bit laptop with Windows 7 Home Premium installed. I just bought a new Windows 7 Professional and legal (OEM) version. How he use to upgrade my version of Windows 7 and keep all my files installed in program files and information? In other words, not a clean install!
Unfortunately, there is no option to do an upgrade, because what you have is an OEM license.
Please note that the Express upgrade does not support OEM, MSDN-Academic, Volume (the student faculty licenses) license. If you are in possession of all these brackets, you will need to save and do a custom clean install. If you want to do it, please backup your Windows 7 Home Premium or according to edition currently installed.
If you want to keep your programs and files, you will need to use a full version or upgrade Windows 7 professional retail license and use the key with the Express upgrade.
Purchase an upgrade with anytime
First of all, check that the edition of Windows 7, you are upgrading is already enabled (if it isn't, you will encounter complications and that you might start all by performing a clean installation). Click Start, type Anytime Upgrade, click the option to purchase a key. Wait while loading of the Express Upgrade page, click on the Windows 7 Professional Upgrade to buy it.
Click Next, fill in your details (it is important that you do this because the product key will be sent to you as a backup in case you need to reinstall) enter your credit card information, click next to begin the upgrade, wait while checking the key, accept the license agreement , click upgrade, wait while the software updates, (it may take 10 minutes or more, depending on the case, updates are required), your computer restarts automatically, after the reboot, Windows 7 will notify its update of the computer, the computer will restart once more automatically and will be completed the upgrade, a windows will pop up by notifying the upgrade was successful and your computer is ready to use, click Close, you should be upgraded to Windows 7 Professional, your files, programs and settings stored, proceed to activate Windows 7 Professional.
well, so that's what I've done so far, I have downloaded the kit of the student digital river, I originally ran Windows xp 32-bit, so when I ran first the exe download, it gave me the error of not being able to record in a single folder to read and what not, but I followed the suggestions on the forums to move forward a burn on a startup disk expandedsetup folder in converting it to an iso, which I did, I installed the first time but missed the option to format my hard drive so my old files were still there, however, once got installed win 7 I wasn't able to connect to internet for some strange reason and I couldn't understand it, so I decided to take the 3 files I downloaded originally from digital river and try their unpacking on the 64 bit OS now I had installed, it worked fine this time without any errors, so I moved the folder expandedsetup to my laptop and he burned them on a dvd as before, this time I boot from the dvd and do a clean install, it installs again very well, but once I login in the OS and I am getting started with things once again everything is grinding the long, I tried to restart and it does not work, this time it froze just a black before the paper screen, so once more, I started from the dvd and tried to do a clean install, but this time, he begins to hang during the part of expanding windows files, so I decide to make another disc using the second expandedsetup folder thinking that perhaps a new one was a bad burn, this does not work either, it takes about 14% of full on the extension of the windows files and then he told me that the files is not found, so I tried the second drive once again, we only got 4% until it gives me error on files is not found , so I put the first early in and try and suspension 4% right now and I expect to give me the same error, I have really no idea of happening, there are too many variables, but I tried to evaluate each of them, would be - this related material? my computer is compatible for win 7 64 bit, I ran the Upgrade Advisor before you buy, so I know that my hardware can run it, I think it's my dvd drive or the hard drive, but they both seem to run fine otherwise, any help would be appreciated
Thanks for posting on the Community Forums of Microsoft Vista.
Installation may stop if the system cannot copy files. Here are some possible causes and solutions for this problem:
· Your Windows installation disc is scratched, smudged, or dirty. Clean the disc with a soft cloth, insert it in the CD or DVD drive, and then start the Windows installation again. If your installation disc is damaged, you may need to replace it. For more information, go to How to replace Microsoft software or hardware lost, broken or missing on the Microsoft Web site.
· Your CD-ROM or DVD drive is not working properly or the disk might be vibrating too much for the laser correctly read data. For more information about this problem, see your hardware documentation or contact the manufacturer of the CD or DVD drive.
· If your computer has multiple CD or DVD drives, your computer may attempt to locate files on the wrong drive. If your computer has a feature to disable CD or DVD drives that are not used, turn off readers that you don't use. Otherwise, try to insert the disc in a different drive, and then restart the installation.
· There is a virus on your computer. Run an antivirus program to scan your system and to identify the necessary repairs. Don't forget to disable the antivirus before you start the installation again.
Also, it is usually caused by hardware or software that is not compatible with Windows 7. If you have this problem, follow these steps:
1. wait 10 minutes to see if the installation continues. Look at the led on the hard drive (often a small light on your computer that blinks when your hard drive is running) to see if there is no activity. If your hard drive seems to be working, the installation must be current. If your hard disk doesn't seem to work, go to step 2.
2. If the installation fails again, it may be a hardware incompatibility problem. Go to the Windows Upgrade Advisor on the Microsoft website to see if your computer can run Windows 7.
3. If you have compatible hardware and your computer still stops responding, disable any unnecessary hardware. Remove (USB) universal serial bus devices. Remove or disable network cards, sound cards and cards of the series; and then restart the installation.
If you have more than 1 Memory stick on your computer, try to remove all but one RAM stick and try to install Windows 7.
If the computer still stops responding during installation, you may need to contact your computer manufacturer or retailer to check if the computer is compatible with Windows 7.
Also check out the link below to learn more about solving Windows installation problems:
Note: This article is related to Windows Vista. However, you can follow the same steps with Windows 7.
If the installation fails after following the steps above, try to note the exact error message and provide the same.

I searched the Internet for the same problem and I can't find a definitive solution or cause for this. It must be the worst installation experience ever!
I have a 9 year old office computer running Windows XP Pro with SP3. The specifications are the following:
Processor 2.0 GHz of AMD Athlon 64 (32-bit)
3 GB RAM
1 GB videocard ATI (Radeon HD4650)
200 GB IDE drive (SATA drive died a year ago)
Sony DVD - RW drive
There is no floppy drive on this desktop computer
I decided to do a clean install of Windows 7 on it, I could test VS2012 and office 2013. I installed the Windows 7 Upgrade Advisor and everything checked very well for compatibility. I have downloaded Win 7 Ultimate x 86 with SP1 from the MSDN site, formatted the drive and installation. He stopped at 0% a couple of times saying: "Windows cannot install required files. The file may be corrupted or missing. Make sure all files required for installation are available. and run the Setup again. Error code 0 x 80070015. »
Then I downloaded Windows 7 Ultimate x 86 and burned another DVD with verification. I tried with this. Formatted the drive, deleted the partition, created a new partition and created the 100 MB system partition. This time he went to 89% before launching the same error: "Windows cannot install required files. The file may be corrupted or missing. Make sure all files required for installation are available. and run the Setup again. Error code 0 x 80070015. "It does not get stuck at 89%, it reached 89%, stays there for a minute and then this error message.
I gave up and I'm back to install Win XP on it, which took place without a hitch. What is it? Too old hardware? Therefore, shouldn't the Upgrade Advisor say before you say it's just good install Windows 7?
Welcome to the community Microsoft and thanks for posting the question.
According to the description provided, you have problems with the Installation of Windows 7 with error code 0 x 80070015.
Error code 0 x 80070015 refers to a device not ready which would normally be on the DVD player.
It is perhaps simply that the installation DVD is corrupt somehow or that the download of the. ISO is defective somehow. Worst case would be a material faullt.
You can try to re-burning at 1 x speed to fork the best chance to burn correctly, or maybe upload again.
If it is an option for you, the other options are the use of a USB key to install from-

installation of games arnt working cd - I get errors
disk defragment simply does not work I click top but nothing happnens - perhaps sumthing to do with priviliages admin, but I am the administrator.
Scan disk does not work as it says system is already used but works if I put it to run at reboot
MY acer DEFAULT factory restore setting does not work it loads but never short - that led me to believe I have no control over my privliages of basic windows system, but I am the adminsitror.
I already had major problems when WIndows would break and stops working when you start up, I managed to solve this problem in safe mode and disabling some start up programs to check the malware was eventually attached to my system using windows scanner and malwarebytes defnder, I managed, but it seems that it is undetectable.
I am unable to afford a new cd for a new clean instalation of windows, I think I need. can someone please
There is no Windows Vista downloads available from Microsoft.
You can contact Acer and ask them to send you a set of recovery disks.
They should do this for a small fee.
It comes to the use of the partition Recovery of Acer to restore factory settings.
Note: During the process, all data stored on your computer will be overwritten. This means that all of your files, such as e-mail and photos, will be deleted. Therefore, we recommend making a backup of all data before starting the recovery process.
To start the system recovery:
- Restart the computer.
- When the Acer logo appears on the screen, press the left Alt and F10 keys.
- If you are prompted with a Microsoft Windows splash screen, press the Enter key.
- After that the Acer eRecovery Management application is loaded, select your type of restore.
- Read the review and then click Next when you are ready.
- Click Next to start the restore process. It may take 10 minutes up to an hour fom anywhere to restore.
- Once the restore is complete, your computer will restart. After the reboot it will load Windows and start the installation of your software and drivers. Your computer will restart several times during this process. Once they are all completed, your computer will be like it was when you bought it first.
Some manufacturers have more available Vista recovery disks.
If this happens or the recovery Partition is damaged, you may need to try this instead:
You can also borrow and use a Microsoft Vista DVD, which contains the files for the different editions of Vista (Home Basic, Home Premium, Business and Ultimate) must be installed. The product key on your computer / Laptop box determines what Edition is installed.
Other manufacturers recovery DVDs are should not be used for this purpose.
And you need to know the version of 'bit' for Vista, as 32-bit and 64-bit editions come on different DVDs
Here's how to do a clean install of Vista using a DVD of Vista from Microsoft:
"How to do a clean install and configure with a full Version of Vista '
And once the operating system is installed, go to your computer manufacturer's website and get the latest drivers for your particular model or laptop computer.
And phone Activation may be necessary when you use the above installation method.
"How to activate Vista normally and by Activation of the phone '

> I plan to do a new installation if winows pro 7 64 on my machine of retail disk
Do it. Where is the problem? You don't need to be. Before the installation of recovery starts everything will be removed and you will have own OS preinstalled. Recovery image contains everything you need, as well as some xxx files are not necessary.
> Also is there a way to preserve the thing about Toshiba Recovery with a new installation? (whats fi I format C only and preserve the system folder and the folder of Toshiba Recovery?-the recovery job?)
Somehow your questions are confusing to me. What you need is to check all recovery options and learn how it works. In the past, ask strange questions as much then I recommend you follow (I did in the past too):
-create recovery discs (DVD-R)
-Test each recovery possible option to understand exactly what is happening
If a problem occurs, you can use the created disks and have once again the factory settings.
I have problems to install updates on my laptop. I have discovered that the destination Windows file is missing or damaged. Someone knows how to solve?

Repairs available for download? Any help is appreciated.
You can try to access the advanced boot option by pressing the F8 key immediately after laptops were turning on/off.
Then you could try using the option called last known good configuration.
