There is a very functional system of protection against fatal failures, and most importantly, very user-friendly. It's called System Restore, or System Restore. System Restore, invisibly for the user, takes an exact "snapshot" of the system, storing in a special folder not only the Registry files, but in general all important system files and libraries. The user can take a "system snapshot" on his own - for example, before the next risky action.
Instructions
Step 1
To return the system to one of the "checkpoints" created by the program, go to the Service menu All programs folder and click on the System Restore shortcut.
Step 2
Select the desired "restore point" by clicking on the desired date in the built-in calendar. After rebooting, the system will complete the process and return to the state in which it was at the time of the "point" creation.
Step 3
Recall that the "point is created automatically" at the time of installation of the program - but it can also be created manually. To do this, after starting the System Restore program, select Create a restore point. And in a few minutes the "cast" of the system will be ready. Give it a name - for example, "Stable System".
Step 4
Unfortunately, the touching concern of the System Restore program to preserve the maximum possible number of "restore points" turns into a serious loss of disk space. You can set as many megabytes as you need under the System Restore folders. Open Control Panel, then click the System icon. Now select the System Restore tab and click the Options button. Here, using the cherished "slider", set the value from 200 MB to 1 GB - an average value, sufficient for a "home user".
