state using System Restore
1. Reboot your computer into Safe Mode with Command
Prompt. To do this, turn your computer off and then
back on and immediately when you see anything on the

mode”, where you can choose to see advanced repair
options. On the next screen, you will need to click on the
Troubleshoot option, then select Advanced Options and
select Windows Startup Settings . Click on the Restart
button, and you should now be able to see the
Advanced Boot Options screen.

2. Using the arrow keys on your keyboard, select Safe
Mode with Command Prompt and press Enter on your
keyboard.
3. At the command prompt, type rstrui.exe , and then
press ENTER .
Alternatively, if you are using Windows Vista, 7 and 8,
you can type: C:\windows\system32\rstrui.exe , and
press Enter . And if you are a Windows XP user, type C:
\windows\system32\restore\rstrui.exe , then press
Enter .

list of restore points. Try using a restore point created
just before the date and time the Police Ukash or
