I would be surprised that a Windows Update damaged My Computer like that.
Can you clarify what you can see? Look at the image below;
Do you only see the blue window header bar, and nothing underneath that?
What about other Explorer windows, like My Documents, My Pictures, or Windows Explorer, are they all the same?
If so I would either navigate to System Restore, (Start > All programs > Accessories > System tools > System Restore), select the restore point you created before updating Windows this time, and restoring the system back to that time/date.
Or Uninstall the updates that were downloaded and installed.
When trying to open "MY Computer" on the start menu I get the Logo header but nothing below the blue logo. no devices, no 'C', 'D', etc. drives. The only thing that has changed since I last tried to go there is that I updated to Netframe 3.5 and a few other updates from Microsoft.
To my way of thought they sure can't get it done a Microsoft like they can at Apple. They update an download, as with Netframe, within days of the intiial update, this all robs computer speed due to disc storage.
