Windows Error Code 8024402F Windows Update encountered an unknown error

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. :-)

Make sure you don't have active X filtering on your router enabled I found that out earlier today after fighting with it I thought at first it was entirely Microsoft and windows activation issue with regarding a recent upgrade to my system. In the end I found it was not, It was a problem of that Microsoft made it require active X controls enabled in it's entirety which is a security risk in and of itself. I highly recommend only enabling active X once a month to do your updates and then re disabling it afterward, too many holes in active X to think that a attack couldn't sneak through it such as a auto downloaded spy ware, ransom ware, etc. The worse thing about active X is it allows somethings to occur without notification of it having occurred.

Thank you, you just solved the mystery! Really figures they'd require Active X... ridiculous.

I have the same problem. On mine, it's a fresh install of Win 7 Ultimate. Firewall is turned off. No other firewalls installed. I have another machine running Vista Business wired to the same router - Windows Update works perfectly well. I've tried every resolution listed in the multiple threads on multiple boards, and nothing resolves the issue.

Microsoft, please do something about this. This very thread is from 2009! This is unforgivable.

have you tried mrchb's fix(synchronizing the time)? it works with mine.
