To reset your computer to an earlier date, you need to use the System Restore utility included with Windows. The System Restore utility only resets the computer's registry and program settings. It does not affect files. System Restore is accessible through the Control Panel or by the Search function.
To access System Restore, open Control Panel. Move the mouse cursor over to the right edge of the screen and pick the Settings icon, then click Control Panel. Then, type "Recovery" into the Control Panel search box. From here, click "Open System Restore" and follow the prompts to pick a restore point and begin recovering the computer.
System Restore works by saving a copy of the system registry at a given point in time, usually after installing or uninstalling software, updating drivers and other actions that affect the system. Pick a restore point that takes place before the issue started and go through the restore process. The computer restarts several times during System Restore even if it seems like it's hanging up. Allow it to complete its progress. Should there be an issue, System Restore aborts the operation and undoes any changes to the computer. Also, it's best to keep the system plugged in to prevent battery drainage.
