The Microsoft

®

 Windows

®

 operating systems 

provide a System Restore option which allows 

you to restore your computer to an earlier 

operating state (without affecting data files) if 

changes to the hardware, software, or other 

system settings have left the computer in an 

undesirable operating state. Any changes that 

System Restore makes to your computer are 

completely reversible.

may appear. If you are an administrator on 

the computer, click Continue; otherwise, 

contact your administrator to continue the 

desired action.

In the event that System Restore did not resolve 

the issue, you may undo the last system restore.

NOTE: Before you undo the last system 

restore, save and close all open files, and 

exit any open programs. Do not alter, open, 

or delete any files or programs until the 

system restoration is complete.
