Yesterday I was dumb enough to install Windows 7 Service Pack 1 in my HP dv6-1253cl laptop and now all programs in my laptop take longer to start up, compared to the day before yesterday. I've installed no additional software or hardware in the meantime. The only difference is the Service Pack. My main program, Call of Duty World at War now takes FIVE times as long to start and also between screens. Response is now also lagging and all programs now freeze for about 30 to 45 seconds before they respond again.
I've tried uninstalling the Service Pack 1, but inexplicably there remain a ton of updates that weren't removed.
Doesn't Microsoft check the quality of the patches they release? What can i do now to regain the performance i had only two days ago?
