Clean Sweep you computer

As i search for different tips on how to make your computer function better, i stumbled into this site which actually did a good job explaining and giving a step by step guide to make a clean sweep on your computer. Read along.

Decide which programs to purge

The first step is to decide which programs you no longer need. For the best results, it’s a good idea to keep only the programs you use regularly. If it helps, make a list of programs you want to keep and others you can do away with, or store on disk.
Has it been a year since your child touched that action game? Chances are you still have the original CDs anyway (should you want to reinstall it in the future), so perhaps it's time to wipe it off the hard drive. Have your music tastes changed since you went through that country-and-western stage? You can easily delete downloaded MP3 files—or at least burn them to a CD to free up space on your PC.
If you're unsure about a program that's on your hard drive, you can always do a search at your favorite search engine (e.g., Bing) to see what it is. For example, if you don't plan on buying a camcorder, remove any preinstalled video-editing software that may have come bundled on your PC.

Ready, set, "Start"

The easiest way to remove a program from your hard drive is to look for an uninstall or remove option from within its program group. You will find this by clicking the Start menu, then All Programs (or Program Files), and then choosing the program that you want to uninstall.
Once inside this program group, you will usually see an icon to launch the program, a ReadMe file (documentation that tells you how to use the program), and, for our purposes, an option that enables you to remove or uninstall the program. Click this and follow the onscreen wizard to safely remove the program from your PC. You may be asked to reboot your computer. Only click to do so once you've saved everything that's open at that time.
Quick tip:
If you want to free up even more room on your hard drive, go to Computer (or My Computer) or Windows Explorer and right-click on the letter associated with your hard drive (usually C. Click Properties, then click Disk Cleanup. Check off the desired boxes and it will tell you how much space it can free up.
When uninstalling a program, you may also get a message that says the program can remove a file that may be shared by another program. To be safe, keep these suggested files on your PC (they shouldn't take up much room on your hard drive, anyway). Similarly, when you uninstall a game, the program may ask if you want to keep saved game files (i.e., a bookmark of your progress). If you think that you will reinstall and play this game again, you can choose to keep these files.
Sometimes the program group may be the company's name. Move your mouse over the name and it will reveal which program(s) are inside.
Quick tip:
If you download a .zip or .exe file from the Web and then install the program to the hard drive, you can delete the original file once it's successfully installed.
Keep in mind that your PC automatically creates restore points while you're using your computer. That way, if you accidentally delete a program that you want to keep, you can revert your PC back to an earlier time. To do so, click the Start menu, then All Programs (or Program Files), then Accessories, and then System Tools. Click System Restore and the program will guide you through the steps.

Take "Control"

Some programs do not give you the option to uninstall them from a program group. No problem. You'll need to go to the Start menu, select Control Panel, and then under Programs, do the following:
Windows 7 and Windows Vista users: Click Uninstall a Program.
Windows XP users: Click Add or Remove Programs.
It may take a few seconds for this page to load but once it is finished, it will display a long alphabetical list of installed programs. Once you see the name of a program you no longer want on your hard drive, click it, and then do the following:
Windows 7 and Windows Vista users: Click Uninstall.
Windows XP users: Click the tab to the right of the program, which will say Remove or Change/Remove.
Follow the prompts. A progress bar will show you how long it will take to safely remove the program. When it's finished, you will see the list once again.
Go through the list, but leave those programs that you are unsure of. Remember—you may use Microsoft Word all the time, so don’t uninstall Microsoft Office, as Word is part of it. Some programs may not be familiar to you, but are required for another to run—a rule of thumb is to ignore it, especially if it doesn't take up too much space on your hard drive (you will see how many megabytes on the right-hand side of the program name). If the program is spyware or adware, then you may want to leave this for your spyware/adware program to sniff out and safely remove. You can download the free Windows Defender to help with this task.
Quick tip:
This article focuses on uninstalling entire programs, but it's even easier to delete individual files. Once you're inside (My) Computer or Windows Explorer, simply highlight the files that you no longer want on your hard drive and tap the Delete key or right-click and select Delete. This will send all unwanted files to the Recycle Bin for safekeeping—until you're sure that you no longer want them.
