Start OTS. Copy/Paste the information in the quotebox below into the panel where it says “Paste fix here” and then click the Run Fix button.
[Empty Temp Folders]
[EmptyFlash]
[CreateRestorePoint]
The fix should only take a very short time. When the fix is completed a message box will popup telling you that it is finished.
Depending on what the fix contains, this process may take some time and your desktop icons might disappear or other uncommon behavior may occur.
Then run OTS and hit the cleanup button
