I have an HP Probook Core i3 with 4GB of ram. Until recently, this machine was plenty fast enough for anything I wished to do. On the day after Patch Tuesday, everything went to Hell in a hand basket. The laptop is on a domain controller at work and Group Policy forced the update automatically.
After the updates, (26 *&^$$*&^ updates at once!), the machine was painfully slow. Outlook, in particularly is very sluggish and any attempt to send a new message hangs ever 4 or 5 seconds (for about 5 seconds each time) until I close the message half an hour later.
After about 20 system restore operations to remove all of the patches in an attempt to go through them one by one, I am very frustrated. I had our sysadmin remove me from GP temporarily so I could troubleshoot, but I have not been able to track down which update in particular is causing this.
If I restore my laptop to a point before the patches, it works perfectly fine. I was able to apply all of the Office 2007 patches with no ill effects. There were approximately 14 patches for .net, and I am relatively certain that one of these is the culprit. I have disabled all four .net services on my machine, yet the issue persists. For clarification, these services are: .net version 2 X86, .net version 2 X64, .net version 4 X86, and .net version 4 X64.
When I run resource monitor, I do not see CPU usage is reasonable but Outlook keeps "not responding" and displays the "blue circle of despair".
Any help is greatly appreciated!
