If you run into problems right after you installed or downloaded new software or you are suddendly experiencing issues that you hadn't previously you might want to try a System Restore. A System Restore sets your computer back to a previous installation.
You will not lose anything. It just sets your computer back to a previous day before the problem began and hopefully resolves the problem. You can select how many days you want to go back to.
Here's how it's done:
Go to Start / Help and Support / Undo Changes to computer with System Restore / Click how far back you want to go on the calendar. If that doesn’t work go back a few days more.
