WindowsUpdate error 0x8007277a, MSE not updating either

Had a laptop that stopped loading Windows Updates following a spyware infection and subsequent clean-up by MBAM. Internet access was ok.

Eventually tracked the fix down to a winsock reset ...

Look in Start > Accessories and find Command Prompt
Right-click and Run As Admin

Then type ...
     netsh winsock reset
     netsh int ipv4 reset

You should get a prompt to restart the computer. We didn't need to, restarting the Windows Update service was sufficient to get everything working again (Start > Control Panel > Admin Tools > Services)

[Just as an aside, we had already run the Microsoft Windows Update Fixit tool and renamed the SoftwareDistribution folder - just in case the above netsh commands don't work on their own]

Uninstall Exchange Server 2010 SP3 Rollup 8 requires msexchange.msi

Having been caught with an SBS 2011 server that had the Exchange Server 2010 Service Pack 3 Rollup 8 loaded, just before Microsoft withdrew that update. Apparently it caused connection problems with Outlook clients, although we had no reported issues.

Before you start make sure you've downloaded Exchange 2010 Service Pack 3 and run it, so that its unpacked in a handy directory.

Going into Control Panel > Programs > View Installed Updates, you should see Exchange 2010 SP3 Rollup 7 and Rollup 8.

Select and uninstall Rollup 8. It takes a while to complete but will prompt for the location of msexchange.msi. This is actually the original  SP3 installer, not anything to do with RU7 which is what you'd expect. So when it prompts, browse to the SP3 directory mentioned above, where you already unpacked the files, and choose that msi file.

The RU8 will uninstall and appear to leave RU7 on the updates list, however in reality your Exchange server is now all the way back at SP3 with no Rollups at all.

Reinstall Exchange 2010 SP3 RU7 to bring it back up to date - and wait for MS to reissue RU8.

Bad week for faulty updates!

Microsoft Update error 0x80244022

Just been on the Microsoft Update website (WindowsUpdate) and received error 0x80244022 from three different PCs. Just worked out that if you leave that error open on the screen and go to File > New > Window and run the Update a second time it works ok :-)

Those pesky Update errors just keep coming.

WindowsUpdate 0x8000FFFF fix

Just built a PC for someone with one of GigaByte's GA-73PVM-S2H motherboards. Its a nice spec nVidia based board including DDR2-800, VGA, DVI-D, HDMI, eSATA, 1394 Firewire (rear and front), SPDIF, 7.1 HD sound and support for 10xUSB - don't think there's a lot to compare at the price. I loaded Vista Home Premium OEM without incident, went to check WindowsUpdate and was greeted with error 0x8000FFFF which sounds like some non-specific default message. Trawling Google (but not Microsoft support) throws up similar errors and recommendations to uninstall update KB929777 - ah, but I hadn't actually loaded any updates so far. I did wonder whether not activating during install or immediately switching to Microsoft Update (i.e. Windows + other products) caused the error?

Fortunately at Ask Leo there's a comment from Mark Lewis / Eric M referring to some keys to delete in the registry (take a backup first!). Start regedit and head into HKLM\Components and remove the keys for PendingXmlIdentifier and AdvanceInstallerNeedResolving. Then restart and try WindowsUpdate again. Gotta be on the right track when the messages change from red to yellow :-)The update loaded in a blink with no prompts and and I had to manually run an update check again - now we were in business ...

0x800700C1 fix

Probably spent way too long getting this school PC working again ...

In short
As you tried to login to Windows XP Home (SP2) it showed a message and logged out again.

A problem is preventing Windows from accurately checking the license for this computer. Error code: 0x800700C1

The suggested fix for error 0x800700C1 had been try re-registering regwizc/licdll or see 310794 from MS and if they don't work reinstall/recover XP - and more than likely lose your applications and settings.

In short, the answer I found was to uninstall Windows XP Service Pack 2 (SP2) using Safe Mode, which gets rid of the Windows Genuine Advantage that's causing the error. Then reboot and reinstall SP2 which resets WGA. I had to activate again (prob from resetting wpa.dbl earlier) and then install IE7 from MS Downloads before I could run WindowsUpdate.

[After reinstalling IE7 I got error 0x800703EE from WindowsUpdate which I traced to c:\windows\system32\wups2.dll - file length was 0 bytes. Deleting the file and reloading WindowsUpdate fixed that.]
