You are doing something wrong there
Software giant Microsoft is pondering what the hell went wrong
when a stability upgrade it released last week for Windows 7 made its
flagship OS less stable.
According to a thread on Microsoft TechNet, the update (KB977074)
causes screen freezes and hangs the boot screen. At shutdown the PC
often hangs with a message that a program is still running but if you
force the program end it does not work. In the end all you can do is
swear and hit the power button.
Some people are complaining that they got a message indicating they
needed to validate Windows 7. The revalidate succeeded, but was a pain
in the bottom. Windows media centre shuts down at will.
Microsoft moderator Arthur Li responded in the thread and recommended
that users experiencing the issue should update their BIOS and their
hardware drivers, disable any antivirus program they have installed,
restart their computer with a clean boot, and try installing the update
Microsoft is apparently still scratching its head to work out what is
causing the problem. It is not convinced that it is the patch.
