I thought I had blogged this before, but apparently not as someone asked me for this again today.
If your server keeps on prompting you to install KB907747 even if you decline the update, the fix is simple. I found this on a site, I just can’t remember which one! (In theory, this should work for any updates that keep prompting)
Create a batch file with the following in it:
net stop bits
net stop /s wuauserv
regsvr32 /u wuaueng.dll /s
del /f /s /q %windir%SoftwareDistribution*.*
del /f /s /q %windir%windowsupdate.log
regsvr32 wuaueng.dll /s
net start bits
net start wuauserv
wuauclt.exe /resetauthorization /detectnow
Run the batch file, and your local Windows Update cache will be cleared and reinstalled. The prompts should stop for older updates.
