Is it possible to selectively delete restore points in XP?

I think the title says it all - more or less.

Some are created as a safeguard before changes being made to the system, and, once it it is apparent that are no ill effects, are in many cases redundant and simply hog disc space.

I would like to be able to delete some of these, while retaining others.

Is this possible?

 

Pretty sure crap cleaner will allow this.

 

Just done this earlier today using http://www.majorgeeks.com/CCleaner_Standard_d5125.html

 

Thank you both. I had forgotten that.
