How to create a restore point
First Right click on the start menu and select System it is near the top.
On the left side of the screen you will see System Protection, Click on that.
It will bring up the following window.
In the area of Protection Settings if the Protection is turned off Highlight the entry and select configure.
After turning the system protection on set the Max Usage, I set mine to about 10% give or take. Click apply then ok.
After you turn on the protection click on Create and name the file what ever you want.
Let it do it's thing and you are all done, you have created a restore point. You should create a new restore point about once a month for safty reasons. That way if you do run into a problem you can always go back to when your computer was running fine.
