Helping people with computers... one answer at a time.
System Restore is allocated a certain amount of space on your hard disk. If that's excessive, you can use less, at the cost of fewer restore points.
Is there anyway to make System Restore use less space if we would like to have the benefit of a restore, but not use up all our space? I just saved half my hard drive by taking System Restore off.

Yes, we can adjust the amount of disk space that System Restore will use.
But that adjustment comes at a price.

First, I need to be very clear about something: System Restore is not a substitute for backing up. System Restore will not restore everything, and in particular, if you lose data files and expect System Restore to recover them, you're likely in for a rude surprise.
System Restore is best thought of as a backup of your System Registry, and maybe a little bit more. While it might save a few more things than just that, that's the safest way to think of it.
System Restore works by saving a copy of whatever it is that it saves to some pre-allocated space on disk. Each time a new restore point is created it's placed in this space, and when that space fills up the oldest restore points are removed to create room.
You can adjust that pre-allocated space and make it small, but the price is that your system will then save fewer restore points - you won't be able to restore as far back as you had before the change.
Right click on My Computer, click on Properties, and then click on the System Restore tab. Make sure the Turn off System Restore checkbox is not checked. (Uncheck it if it is, and click on Apply.)
Click on your C: drive in the available drives list, and click on Settings...
Here you can see, and control, the amount of disk space allocated to System Restore. In my case, a maximum of 12% of my disk space is made available.
If you want System Restore to use less space, then simply drag the Disk space to use slider to the left to whatever amount of space you'd like to allocate.
If you turn System Restore off, then no disk space will be used.
Personally, I run with System Restore off, and rely on my nightly system backups as my safety net.

Leo A. Notenboom has been playing with computers since he
was required to take a programming class in 1976. An 18 year career as a programmer at Microsoft soon followed.
After "retiring" in 2001, Leo started Ask Leo! in 2003 as a place for answers
to common computer and technical questions. More about Leo.
I've been using XP for eight years and never once had System Restore running or ever used it.
Posted by: Mark at January 28, 2009 2:42 AMWith regard to Karl's and Polyanna's problem, Sytem Restore will often fail due top Anti Virus programs. Security programs such as Norton and Kaspersky Internet Security, protect their own program files to prevent viruses from attacking them. e.g in Kaspersky, this is known as "self defence". If you turn off this protection in the settings of the secuity program, you will normally find that restore will then work. Don't forget to turn it back on! I have tried using the safe mode method that Simon mentions, but it is not always reliable

I want to reduce the amount of storage space allocated but everything is greyed out any thoughts?
