How to Make a "Clean Day" for Your Computer

Cleaning out your computer at least once a month will make a world of difference in the performance of the machine.

Steps

1
Devote some time into this. Create a batch file, or use Windows Scheduler, if it is available.
2
Start the Following programs, in order:
- Spybot: Search & Destroy. Get it at SpyBot.com; SpyBot takes up to an hour to finish its job.
- AdAware: Google search it, and download it. The point is that AdAware gets what SpyBot does not look for, and vice versa.
- MRT: Go to Run, type in MRT, and hit the "Enter" key.
- Anti-Virus software of choice. Start a full scan.
- Your Registry Cleaner of choice.
- Disk Clean Up; Go to Run, type in "cleanmgr" and hit "Enter". Pick what you want to be deleted, compressed, or otherwise.
- Defragmenter. Go to run, type in defrag, and hit "Enter".
- Windows Live OneCare safety scanner does all of this. Go to OneCare.com and look for Safety Scanner. Run all three tools.

If you are running XP or Vista, press "WindowsKey" + "L" to disconnect your session, when you plan to leave your computer alone. This sends you to the Welcome Screen, with all of your programs still running.

Allow each program to run one at a time.
Never do anything with the computer while defragmenter is running. Doing so could cause data loss.
