My PC was going extremely slow so my friend told me to use Disc Defragmentation and voila! My PC is like new, it works at least 5X faster than before and no longer freezes. What exactly does disc defragmentation do? I was wondering if I should also try "Disc Cleanup" option. Would that make the PC run even faster or should I not use it? He also told me to switch off the Auto Updates as that could be slowing my PC too.

Hiya Speedbird1.

Leave Auto Updates active as they can help eliminate any system holes that MS find.

With regards to Disc Defragmentation (D-frag), it does exactly what it says. As you use the computer and install, delete and move things about, the data is stored on the hard drive (HDD) in bits and pieces (fragments) and not necessarily all in the same place. When you run a program or open a file, it searches the HDD for all the bits to make up that particular option and then runs it but the fragments might be at different areas of the drive therefore taking a while to load fully.

D-frag`ing the HDD sorts all the fragments out and puts them in the smallest area possible which is why you see the blue area (data) being pushed up to one end of the drive in the graphical picture. The perfect D-frag would be to see a solid lump of blue on the left with maybe a splash of green (the page file) at the end.

My mind sees it as a warehouse containing boxes that are half full and to make a complete item, you have to look through all the boxes to find all the bits. If you give it time, D-frag`ing does that for you so all the boxes are in one corner and are all full. If you D-frag regulaly, the time it takes gets less as it doesn`t have so much to do each time.

By all means use the Disc Cleanup option as that`ll get rid of a lot of unwanted rubbish if you make sure all the boxes are ticked but if you haven`t used it for a while (or ever), it could take some time so be patient but cleaning up before a D-frag is always a good idea otherwise you`re just tidying junk.
