original title: Windows Update still giving error Code 8024402F Windows Update encountered an unknown error even after fresh install (Win7 Professional x32 and x64)

Hi,

I recently installed Windows 7 (fresh install). Prior to that, I was using Windows Vista and everything was working OK.

I upgraded to Windows 7 Pro x32 bit (using the download version), installed various softwares and everytime I tried updating through Windows update, I get the error Windows could not seach for new updates: An error occured while checking for new updates for your computer. Error(s) found: Code 8024402F Windows Update encountered an unknown error.

I clicked on "Get help with this error" and used the "Windows Update troubleshooter" but it could not find the error.

A week later, the problem still persisted and decided to redownload the entire windows 7 but this time downloading the ISO version and installing the x64 one. As soon as it completed installing (no other software installed even antiviruses), I immediately tried running Windows Update. I got the same error message. Tried doing the "Windows Update troubleshooter" to no avail.

This might also be related. In both installations, I also tried to set up Windows Media Center. When it tried to install PlayReady, it gave me the error: An error encountered while downloading the installation package (Error code: 0x80240022). When I ignore that, the next phase (downloading TV setup data) stops with a one tiny dot in the progress bar-- even after half an hour.

Again, I used to use Windows Vista and it updated fine without any issues. In my Windows 7 installation, I am able to connect to the network, surf the internet, download files, and use various software (e.g., Yahoo Messenger, Skype, Kaspersky Antivirus which updates fine).

Hope you can help.

Thanks!

Regards,

Jay

@Uma R    - Microsoft Support.

Thank you for your information.

Actually I was about to advise of a work around that worked for me, all that was necessary was to turn off the Windows Firewall.

Of course this is not a final solution as it is obviously not a good idea to turn off the firewall while downloading, also after I turn it back on I assume Automatic Updates will again be blocked. A message to the effect that Automatic Updates were being blocked was what first drew my attention to the problem.

I would suggest that someone on this forum who is in contact with the appropriate Microsoft group should pass on this information for a correction to be organised. Now that I can download Updates I should be able to install it.  :-)

Regards

    Ok, so here is my setup.

    Win 7 ENT x86 in audit mode getting ready for sysprep.

    Install office 2010, install required cisco Soft phone, and necessary software fro the Service desk... ie Adobe reader, 7zip and google chrome.

    Do all windows updates, restart check windows update again....Error  8024402F.

    Search the whole damn internet and try every single possible fix there is but NOTHING nada zip, still same problem.

    Start from scratch with the image and same thing....

    Then started uninstalling updates one by one, restart and low an behold problem was fixed.

    All i did was uninstall .(dot)NET Framework that windows updates had installed and viola win updates work again.

    Manually installed .NET afterwards and its all good again.

    So if you were as stuck as i was try uninstalling .NET framework from win updates, hope it works for you as well.

    I'm running Vista Ultimate 32 bit x86. Tried everything on here without success until I reached this. Dunno what .NETframework 4 does (or did) . Removed. and downloaded .netframework 4.5and more updates are now downloading It only took me 2 days to resolve the issue but thanks for this.

    To fix this particular error, run System File Checker. Firstly, scan yoru registry with <removed> and fix any computer errors detected. If the problem still persists, go through the following instructions:

    1. Click Start, point to All Programs | Accessories.
    2. Right click Command Prompt, select Run.
    3. Type SFC/ SCANNOW
    4. Press ENTER key.
