Here is a great tip to free us some of your hard drive space that's been in use for some time. It's not recommended for all user's but it's a great tweak.
The XP System Restore is a great utility. If you mess up something on your computer. You just flip the switch and go back to an earlier time. Occasionally I use it to free up hard drive space and well as a solution to clean up a virus infested PC.
By clearing up your hard drive space your computer has more space for storage and system backup now will run more efficiently.
There are time when the XP System Restore utility is infected with a virus and the only way to fully remove the virus from your PC is to use the Symantec or McAfee website to show you how. But once the virus is removed, it can easily return because of your automatic System Restore utility. All you need to do is after a virus is removed, disable the System Restore utility and run a system check for the virus again.
To Disable XP System Restore.
First go to my computer to see how much hard drive space you have left on your c drive. Note it.
Then go to Start -> Control Panel -> System -> click on the System Restore tab and check turn off System Restore and click ok. Go to my computer and if everything work, your c drive should be free of hard drive space. Now go back to the Control Panel -> System -> System Restore tab and uncheck the turn off System Restore button and now everything goes back to normal. You system will now continue to backup as usual with more hard drive space.
