A computer is used by many to run programs and surf the Internet. As a result, system files on a computer can get corrupted or infected by viruses and spyware or malware. One solution that is available is to reset the computer back a day. Going back to a previous day's configuration will restore any files that have been corrupted back to the way they were the previous day.
Step 1
Use the system restore feature that is built into the Windows operating system to restore the computer to the previous day. Click the "Start" button, select "Programs" and then "Accessories." Click on "System Tools" and then "System Restore."

Step 2
Restore a backup of the Windows registry. A registry cleaner such as RegSeeker will make a backup of the registry each time the program is used to clean the registry. The program is free for anyone to download and use.
Step 3
Open the program and click on the Backup option on the left and then double-click the backup from the day before. Click the "Restore" button to apply the registry settings from the previous day. Restart the computer.
Step 4
Boot the computer into a DOS prompt and choose the last known good configuration. Press the "F8" key during the computer's boot up sequence to go to a DOS prompt. A list of options will appear on the screen.
Step 5
Choose which option will be used to start the Windows operating system. Use the previous known good configuration to reset the system to the previous day's settings. Press "Enter" to change the configuration and to continue loading Windows.
