HowTo Quickly Deep Clean Your System
It is really easy for your computer system to get full of junk. This is one reason why people often notice that their computer system seems to be slowing down.
This post will show you how to set up the built-in disk cleanup program in Windows to perform a deep clean of your system so that it will run quicker.
Configure the Disk Cleanup Program
The first step is to get the disk cleanup program to free up as much free space as it possibly can. Follow these steps:
- Go to Start→Run… and type in
cleanmgr /sageset:99 - You should now see the Disk Cleanup Settings window. In this window, check off all of the options. Once you have done this, click on the OK button.
Your cleanup manager is now ready to perform a deep clean.
Performing a Deep Clean
To run the deep clean, simply follow these steps:
- Go to Start→Run… and type in
cleanmgr /sagerun:99 - The disk cleanup program will now run. It will close automatically when it is finished.
The deep clean may take some time the first time that it runs but if you run this on a regular basis, then you will find that this process becomes quicker each time.

February 21st, 2007 at 8:44 amNot a bad idea at all! I work as a police dispatcher, and our computer (Win XP) is running 24-7, so we tend to accumulate a lot of crap, and none of my co-workers are tech-savvy, so it’s up to me to clean up after them (I don’t mind, really).
I think I’ve mentioned it before in the comments area (and I have nothing to do with them other than being a fan), but CCleaner is an awesome, free tool. It has a disk cleanup tool that hits all of the points the Windows-included one does, and it also has a registry cleaner to find all those little issues left over by years of install-uninstall. The first time you run it, you’ll be surprised.
It also includes an alternative to the Windows Add/Remove dialog - and this one lets you remove those entries that Add/Remove just gives an error on when you try to uninstall.
My favorite point, though, is that it’s free - meaning easy to take along and use on almost anyone’s computer.

command?
I forget how to do it exactly. Thanks. -

February 22nd, 2007 at 3:15 amThanks Tim, I’ve now added “cleanmgr /sageset:99″ as a shortcut in our custom remote support package and I’ll also look into modifying my DIY Remote Tech Support build to include it too.

February 22nd, 2007 at 7:27 amThe one thing I would not reccomend is allowing CCleaner to compress my old files. While this would save a lot of space, anytime you access a compressed file, it will be slower. Otherwise I really like it. Saved me about 450Mb of wasted space

February 22nd, 2007 at 8:38 amThe reason I first discovered, and switched to, CCleaner over the default Windows tool is because the latter always froze up and crashed.

February 22nd, 2007 at 4:31 pmFor what it’s worth,
You can use cleanmgr /sageset:n where n=any number 1-99 and then /sagerun:n …this enables setting up different cleaning profiles for example one that compresses old files and one that doesn’t.
