A simple trick to get rid of files that you think you deleted but haven't actually gone or just can't get rid of is to delete System32. System32 is a program that holds a record of your browser history, all your deleted bookmarks and all your deleted programs. Its where your recycling bin would go if you tried to delete it. Just go into start and go to my computer, then search for "system32" and WAIT FOR EVERYTHING TO LOAD! Then simply select it and delete it. Make sure you delete all of it or your computer will become very slow because its searching for files that don't exist, but if you get rid of all of it then it won't even try to find those files because the programs that searched for them won't exist. Basically if you delete System32 then your computer will run much faster and will also have more room to store things. Because when you delete things, they aren't actually deleted for 6 months because microsoft have to keep a record of such things to make sure your not doing anything illegal or being a terrorist. Deleting System32 will also get rid of a lot of viruses because thats where virus coders like to hide them since most people don't know what system32 is. Hope this helps you with all your computer problems Mossy! have fun with your new faster PC after this.
