Re: Vista working very slow
I think the problem could be with your hard drive. As you have mentioned just 10Gb Space is left, that is too small for giving performance on operating system like Vista. Its just not enough to run Vista properly. If we compared XP or any windows with Vista, this is the one that uses HDD more than any other operating system.
You should check out your drive and see what all stuffs are eating up your space. You should probably delete few system restore points. They use to consume too much space. Run Disk Cleanup and free up some space.
