I bought my Dell computer in 2012 and had to reload my Windows 7 but my product key at the bottom of my computer is worn and I was wondering if it is possible for Microsoft to have a copy of it.
No, unfortunately.
But since you bought a Dell computer, it provides a DVD of free relocation for each model, which is a clean copy of the OS without the bloatware factory but just a logo and a standalone activation. Order here: need backup Media? Reference Dell U.S.
I would not use the drivers disk unless you need to install the driver of LAN network to get online. Instead, follow these steps to clean reinstall Windows 7, install all your Important and optional Windows updates until no more are available, so all still pilots missing in Device Manager must be imported from the Web page of the Dell Support downloads for your tag number.
Other than that if you still have the recovery partition on the disk Dell and it does not start after restoration of PC Dell Windows 7
Then, you can try to run it manually after the recovery Partition to start using EasyBCD . This also activates the self.

Product key not working not not on Windows 7
Original title: Windows 7 download
I have a pre installed Windows 10 PC. I want to downgrade so I tried to download Windows 7 from Microsoft. It said to insert my product key, but it does not work. Any tips? It's as if I can download my Windows 10 product key working to activate Windows 7?
Follow the zig - zag. If there are drivers available, here's how you can get the Windows 7 installation media.
Note: This site works often hurts when you enter a product key, bad language is one of the questions. You can also receive a notice to connect with the manufacturing of PC if you have a key OEM supplied with your computer, but it can't hurt to try.
Please read the following information below is one possible solution.
* Edition
More information and alternative resources:
If you have a friend with a version of "Retail" (Full or upgrade media, only in the media that you don't need their key) of the installation DVD (should be the same as your key was for: Home Premium, professional or Ultimate) it will work with your "Retail" or "OEM" product key, if you need to reinstall or repair Windows.
Read the following articles on the Wiki:

I need a vista clean reinstallationof. I jave an Acer laptop and I have the key product for the vista operating system installed which has completely disappeared. How can I get a copy of vista to reinstall?
Hello
See if you have a Recovery Partition of Acer.
http://Acer.custhelp.com/app/answers/detail/A_ID/2631
There is no Windows Vista downloads available from Microsoft.
You can contact your computer manufacturer and ask them to send you a set of recovery disks.
They should do this for a small fee.
Some manufacturers have more available Vista recovery disks.
If this happens, 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 '
http://www.Vistax64.com/tutorials/117366-clean-install-full-version-Vista.html
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.

For about a week now that I get a lot of 'freeze' and try to eliminate contradictory processes that cause my Vista Home Premium 32-bit w / SP1 system to "lock" onto me.
I tried but can't do a restore effective because none of my points of store go back enough to solve the problem.
So I try a "clean boot" as described in article http:// support.microsoft.com/kb/331796.
My system has installed significantly since turning off half of the services non-Microsoft configured to run at startup.
But every time I launch msconfig.exe I get this error message-"a problem when processing custom tools manifest file (C:\Windows\system32\MSCFGTLC. '"). XML ".
It is not stop fiddling with the boot configuration, but I don't think I should get this error. Any ideas on what it is and what to do about this?

Hello ch4rlie1949,
Run The System File Checker utility:
To determine if the problem you are experiencing is caused by one or more system files that are used by Windows Vista, run the System File Checker tool. The System File Checker tool analyzes the system files and replaces incorrect versions of system files by using the appropriate Microsoft versions.
To run the System File Checker tool, follow these steps:
- Click Start and type cmd in the box start the search .
- Right-click cmd in the programs list and then click run as administrator. If you are prompted for an administrator password or a confirmation, type your password or click continue
- To order invites, the following line and press ENTER: sfc/scannow (Yes there is a space after sfc)
This analysis may take some time to complete. When the analysis is complete, test to see if the problem you are experiencing is resolved. Hope this helps you. Let us know anyway. Make it a great day!

Product key not working only not for the upgrade from Windows 7 starter to win 10
I have two Asus EEEPCs came with Windows 7 Starter. The product key is on the bottom of the devices. And they are completely legible. 4 years ago by ish and over the years the installations of Windows crashed, one of them, I installed Linux, the other, I played a bit with the installation of Android. Today, I have upgraded to Windows 10 for each of them, wipe the disk and did a full install from USB. One of them was perfectly, the second installation won't take the period key, the product license. I even tried to change the characters only TWO that could be incorrect due to friction vs O Q and still nothing. is there a way to send an image of the product key to Microsoft and someone to tell me what the heck is wrong with it?
Try to contact support to have reactivated it:

I was in Lightroom and had a power surge and now Lightroom will not launch. He has encountered an error when reading the preview cache and needs to stop smoking. Lightroom will attempt to fix the next time it starts. I closed my system and Lightroom will not always start. Does anyone have any suggestions?
You bet and Yes:
* do not delete entire .lrdata folder
* don't delete anything else
Best?
If so, you can rebuild strength previews (e.g. standard previews of entire catalog) using library-> menu previews.

After Encrypting files, I had to reinstall my windows and now I can not decrypt the file
* O.T. > encrypted files
So after encryption of files I had to reinstall my windows (changed the name of the owner) and now I can not decrypt the file
After attempting to decrypt the files, I'm promped with this message:
Attribute application error
An error occurred applying attributes to the file:

Access is denied. \
I want to say that I added my administrator name in the Security tab, and then gave me full control over the files, but that did not work.
Hello
I understand that you cannot decrypt files previously encrypted in Windows 7 after you have reinstalled Windows.
- What program did you use to encrypt the files?
From now on, I would ask you to refer to similar questions discussed in the thread below links and check the status.
Cannot decrypt previously encrypted files
I'm unable to decrypt files encrypted after reformatting the hard drive.
Hope this information is useful. Please feel free to answer in the case where you are facing in the future other problems with Windows.

I have a rootkit on my computer and I had to reinstall my Windows 7.
I have a rootkit on my computer and I had to reinstall my Windows 7. Is it safe to download it on the same PC - as in, can I start my current Windows normally and move forward? In addition, my Windows 7 Home Premium came with my laptop, I have a product key. How can I re - get the ISO file?
Original title: Rootkit Invasion!
Hi StethoscopeJan,
I suggest that you want to run virus scan in safe mode with network.
Step 1
Start your computer in safe mode
http://Windows.Microsoft.com/en-us/Windows7/start-your-computer-in-safe-mode
Note: When the boot advanced options select Safe mode with network.
Step 2
Run Microsoft Online Scanner.
The Microsoft Security Scanner is a downloadable security tool for free which allows analysis at the application and helps remove viruses, spyware and other malware. It works with your current antivirus software.
http://www.Microsoft.com/security/scanner/en-us/default.aspx
Note: The data files that are infected must be cleaned only by removing the file completely, which means that there is a risk of data loss.
