    Method 2

    If you're still having problems, then you can check in the history of Windows update and the updates recently installed in vain.

    Step 1:

    Check the update history to see what updates have been installed or has failed. See the link for the same mentioned below.

    See the Windows updates are installed

    http://Windows.Microsoft.com/en-us/Windows-Vista/see-which-Windows-updates-are-installed

    Step 2:

    If you see updates failed, you can try downloading and installing the updates manually from the Microsoft download center:

    If you are not real tied to the current installation of Windows - then a cloth and then reinstall are the best way to see if you can fix this

    Here's a suggestion on how to do a 'clean ': install
    [quote]
    For testing purposes, it is best to install Windows "clean".
    It is, basically, install the way that Microsoft intended (with the drivers from Windows Update).
    This procedure is for Windows 7, Vista is similar (but has 2 service packs)

    You will need your installation/recovery DVD (s) before you start.  Once you wipe the hard drive, there is no going back!

    1 back up all your data.
    It will wipe everything off of your hard drive, so what you want to keep should be backed up elsewhere.

    NOTE: If this is due to an infection, remember to analyze the data with current antivirus to another system to locate and remove malware.

    2. connect the system to the internet (if the system shows then disconnect from the Internet, do).

    3. use one of these free utilities to wipe the hard drive:
    DBAN ( http://www.dban.org/download )
    KillDisk ( http://www.killdisk.com/downloadfree.htm ).
    This will also remove the system recovery partitions - so the installation/restore DVD is essential!

    4 install Windows by booting from the installation/recovery DVD - DO NOT change any settings!

    5 visit Windows Update and get all updates

    6. check device for all unknown/disabled devices Manager - if there are unknown disabled devices, secure them with the latest drivers from the website of the manufacturer of the device (not the PC manufacturer)

    7 visit Windows Update and download the Service Pack 1 (normally under important updates).  Read these notes for installing SP1: http://support.microsoft.com/kb/2505743

    8 visit Windows Update and get any other available updates

    9 download, install and update a free antivirus, so it does not get infected during the test ( http://www.carrona.org/freeav.html ).

    If problems persist, then the problem is probably with your hardware.

    Warning: If you have an Asus motherboard, check the date on the file C:\Windows\System32\driver\ASACPI.sys.  2004/2005 is a problem, 2009,2010 is OK.  Updates are available on the Web from Asus site.

    Warning: If you have a Sony system, make sure that you do NOT have the 2007 version (or earlier) Extension of Firmware of Sony Analyzer (SFEP.sys).  To update this driver immediately!

  • During windows 7 Professional 64-bit error code 0 x 80070017

    Hi all! Why when I need to start installing my windows 7 ultimate or proffessional 64-bit using DVD he reached on the expansion of scene files and gives a error code 80070017 0 x and a text saying corrupt file. Earlier, but he did not give this type of error but since I increased my 6 GB RAM it gives this error code during Installation. Can anyone help? Thanks in advance...

    If you have recently installed all new RAM modules, remove them and try to install the new. If the installation is successful, you can reinstall the additional RAM.

    If you have compatible hardware and your computer still stops responding, disable any unnecessary material. Remove (USB) universal serial bus devices. Remove or disable network cards, sound cards and cards of the series; and then restart the installation.

    By your computer previous on the same wire, most likely because you do not have to completely remove the preinstalled Norton free version of evaluation BEFORE you upgrade Windows XP to Vista AND you installed McAfee Antivirus Plus AND BEFORE that you have installed the Vista updates everything (including the Service Packs & IE upgrades).

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 on the option enter a key, enter the key of Windows 7 Ultimate edition at the request, click Next, wait while checking the key, accept the license agreement, click on upgrade, wait while the software upgrades, (it may take 10 minutes or more depending on the if updates are required) your computer restarts automatically, after the reboot, Windows 7 will notify you updating the computer, the computer will restart once more automatically and will be completed the upgrade, a window will appear notifying the upgrade was successful and your computer is ready to use, click Close, you should be upgraded to Windows 7 Ultimate files the stored settings and programs.

  • Unable to activate Windows 7 Professional in spite of being a reinstall of the same product on the same computer

    Hello. I have a computer that was running Windows 7 Professional. The software has been installed on the computer and authentic and purchased several years ago. Due to problems, I had to reformat the HARD drive and reload Windows 7 Professional on the same computer using the same product key.

    Now it will not activate and comes up with an error 0xC004C020 code which States that "the activation server reported that the Multiple Activation key has exceeded its limit"

    I do not understand why this has happened. I bought the copy of Windows 7 Professional on ebay and I have the box, case and the two original disks of Windows 7 Professional, as well as the authentic product key sticker. He was recharged on the same computer that was originally activated copy (same product key)

    I have attached the report of diagnosis MGA below. Would like to find a solution for this. Thanking you in advance.

    Unfortunately a mass activation key is used by the company to activate several PC and not meant or sold for use by consumers.  Understanding the MAK Activation

    When you mention you bought on eBay that explains it pretty well because there are hundreds of early cases of consumers ripped off on eBay by Volume and TechNet keys sold illegally.

    If you don't have any other Windows 7, 8 or 8.1 license to use for the upgrade, what I would do is go ahead a buy Windows 10 and make the Clean 10 Windows Installer that has no complaints and if you stick with the steps in the link results in the best installation of the best OS who's going to stay that way as long as you do.
