Since the problems occurred after installing updates and a third-party
program, uninstall the updates and the third-party program. Make sure
you reboot. Does the computer return to its normal state? If so,
install the updates one at a time. Test the computer. If it is fine,
then make a System Restore point and install the third-party software
and test. If the computer is fine, perhaps the original installations
didn't go well. If the computer is not fine, contact the third-party
software's tech support.
If you install a Windows Update and immediately experience problems,
contact Microsoft:
Customers in the U.S. and Canada can receive technical support from
Microsoft Product Support Services at 1-866-PCSAFETY. There is no
charge for support calls that are associated with security updates.
