The File Removal feature only found 8 mg. of temporary files to delete, out of a total of 6 gigs.... not much of an improvement. The Registry adjustment was equally disappointing, as my computer did not run faster after SM3 adjustments. Only because SM3 did find 8 mg. of files to delete, I gave it a rating of 2 stars.

The program didn't do any harm to my system, but it did not live up to the praise other reviewers gave it.

"Love the privacy feature"
I am very impressed with System Mechanic. It's so intuitive and easy to use that I didn't need to read the help files at all.

I find the "Privacy" feature most helpful - it deletes the browser cache, recently viewed history etc with one click. Also, the industrial strength deletion feature is great. I have been looking for this for a while.

Another useful feature is the ability to control the programs that start up when the OS loads - a lot of programs tend to do that these days, and it is annoying.

All in all, well worth the money.

"Great"
Just installed it and it works great. Many features, fast, efficient, I recommend to all.

"Valuable, Powerful Utility"
System Mechanic takes care of a number of Windows problems, both large and small. The file cleanup function alone is worth the price. Gets rid of all sorts of Windows trash files at the click of a button. The startup manager will let you adjust what comes up when you start windows quickly and easily. Read the help files and check for updates frequently.

"Very effective and powerful... so use it with care"
Having used many utility programs (System Works, System Suite, etc..), I can honestly compare them with System Mechanic.

Pros:
1. It is very effective IF used properly. For beginners use "Maintanence Wizard" this will effectively and safely optimize and clean your OS.
2. "Netbooster" actually DOES make your internet connection faster! I mean Wopping fast, if you have DSL or a cable modem. Even if you have 56K modem, you will consistently see an improvement.
3. Gives you much control over your computer, you can customize your Windows according to your preference quickly.

Cons:
1. If you use System Mechanic manually (i.e., without using "Maintenance Wizard") to fix things, be very careful. You must know what you are doing, or else you might destablize your computer. I recommend "Maintenance Wizard" for safe and effective optimization.
2. No defragment program.

Sum:
Very powerful tool. It really optimized my computer (Win 2000, XP). More than SystemWorks or System Suite.
