Hi,
I hope someone out there can help.
I use 64bit Windows 7. I updated the Service Pack1 and now I can't
seem to uninstall it, have literally tried everything but no luck.
Thought maybe someone has had the same problem with this??
the update wasKB976932/any help or suggestions would be appreciated.
Thanks

Just out of interest, why would you want to do this?

Thanks for you reply,from one old dog to another(can't use the alternative, they might ban me from the forum!!
My PC seemed to work better before I downloaded the service pack so I thought I'd uninstall and see if it changed anything but thanks for your comments David.
Ciao

Remember kirky15, you will have the process mscorsvw.exe (.Net Runtime) recompiling the libraries for up to an hour after the install of SP1 and this can consume ~50% of your CPU. Plus for 64Bit it must do it for both 64 and 32.

A bit of an explanation here http://blogs.msdn.com/b/davidnotario...27/412838.aspx

As for uninstalling SP1 try running this from an elevated cmd prompt (maybe in Safe-Mode).

"wusa.exe /uninstall /kb:976932" allthough if you`ve run disc clean up and removed the back up files i think your goosed!
