So i have tried numerous steps but my vista is buggered. I can't use defragment. It starts but then never finishes. It will change my hard drive space lots. Like first its 48gb. Then a hour later its 52gb then half a hour its 51gb. I even tried Tune-Up Utilities 2009. That will take for ever to work. Like 5 hours! Why??? Cause when i checked it only had 7 percent fragmentation. Surely it won't take over 3 hours to defrag that! And system restore does nothing as i done it lots of times but same result. But i don't want to factory reset since the tune-up utilities code is the last one out of 3 and i don't want to buy a whole new liecence cause my computer went stupid. Why is it taking this long!!!!
