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

    OMG thank you so much. I tried everything else to no avail but this worked for me and my pc now has 15 updates loading onto it yay :)

    Yesterday I found another solution to this error 8024402f

    I did put on two threads,and thought this thread as most used needs to be put on here now

    The results so far corrected 3/3 Windows 7 64bit computers(my own plus 2 others) 0/1Vista s

    An unbelievable simple process.

    I will paste all the information as I first did it is quite a story

    I have had this problem as well and tried alot of recommendations but none apparently worked.On the update box on my computer has  recent time update tried had NEVER.

    So if you have this maybe this will work for you I tried quite a path with all having the same apparent result with the error 8024402F Coming up.

    This is such a mad mad world we live in (murphies law seems to be in control.)

    Do exactly the opposite what is logical

    First set your update setting to NEVER RECEIVE UPDATES, then UNTICK the two boxes below if they are ticked (one about any one can update,) and the other about being informed about available updates.(That one a box comes up are you shore you want not to be notified etc.)

    NOW USING MURPHIES LAW  Leave all settings as is eg NOTHING SHOULD WORK

    NOW CLICK THE UPDATE BUTTON SURPRISE SURPRISE YOU NOW CAN UPDATE.!!!!!

    After updating ,check for further updates after the first batch.

    Then the settings can be put back to normal eg Receive updates Automatically, the tick the other two boxes.

    As you I have Windows 7 64bit.

    I had extra information if not successful ,but appears this first part works well

    Please reply if successful or not so I can update the results So far after 1 day as mention 3out3 Windows 7 64bit computers correct 0out 1 Vista.

    Un.Be.Liev.Able.  Thanks!  I have spent the whole morning fighting with this and nothing worked.  The weird thing is, Windows Update worked fine until now and the only things I did this morning were to install Office 2003 and its service pack, and use Windows Update to download a few innocuous optional updates (video card, monitor and wireless mouse).  Oh, and a Windows Defender Quick Scan.  There is nothing I can see which would cause this sudden catastrophic failure (yeah, catastrophic: try turning off updates for a few weeks and then run a virus/spyware/trojan scan on your computer, if you're able to).  I guess the automatic part of the updating software somehow got so messed up that it jams the whole system when it's functioning.  But I'm not surprised: just another half-day of work lost in Microsoft Paradise, like so many before ...

    Had the same problem with the same error message with Win 7 64 bit.  I found that the problem started when I configured my router to work with IPv6.  It was no problem everywhere else on the Internet but Windows Update does not like it.  I guess it does not recognize the network change and has a security freak-out.  So I reset my router to factory defaults (because it would not allow me to unset IPv6 compatibility when I set it) and that solved the problem.  But I guess I am stuck with IPv4.  Thanks Microsoft.

    So what is the official word from Microsoft about this issue?  This is a topic that has been running for more than 4 years, more than a hundred replies, several Windows versions and after browsing through part of it I see quite a few solutions that work for some people but not for everyone.  From changing DNS server, messing with Internet Time settings (the solution that worked fro me), removing the .Net 4 Client thing, turning off the firewall, running various Microsoft Fixit suggestions, clearing folders, stopping services....   I even have my own theory that Office 2007 could be related.  All that points to multiple types of problems or situations that are not necessarily related and they all produce the same result.  As if error code 2084402F is a generic one meaning that Windows Update cannot continue.

    What gives?
