Summary
Misunderstood Top Cleaner
Theo KApril 12, 2006
Pros
"Registry Washer" was and is by far the best Cleaner among the very best. Anyone who used the real program has the expirience that makes him\her to trust this cleaner more than any other. Imagine, "Registry Washer" is even better cleaner than the excellent "TuneUp Utilities" or "PC Repair" and "Windows Optimizer - Register Cleaner and Fixer", and "Registry Repair", which they are considered to form the Club of Excellence. However, the company made a serious mistake in presenting the 2006 version: This release was just a demo, without giving to the user the possibility to try and find out how good and effective is "Registry Washer". As a result, many people protested and considered this cleaner as a no good cleaner. They are on the right side, as it is not possible for the user to form an opinion without the possibility to try an application. But, though critisizers are justified, "Registry washer" still remains the best cleaner. I did not use this new version, as I already have the paid older version, but I believe that the company realized finaly the mistake, and released with this version a real trial. I suggest everyone to try "Registry Washer". It respects absolutely your system and corrects more problems than any other cleaner.
Cons
The only disadvantage of this cleaner is the fact that, at least the previous versions were very slow in scaning. But how can a cleaner be thorough and effective and be very quick? Unless if this new version is feast... In this case I will buy this new version. Try "Registry Washer".
Summary
Precious cleaner
NestosJanuary 19, 2006
Pros
After you scan with any other cleaner and your registry looks entirely error free, use "Registry Washer" and you will find that there are a few dozens of (REAL) errors to be repaired. On the contrary, if you clean your registry with "Registry Washer" first and then you scan your registry with any other cleaner, you will find no remaining error. This cleaner is precious.
Cons
The weak point of this cleaner is slow speed. It takes 42 minutes to scan my system (13GB). But how "Registry Washer" could scan so thorough and be fast? Oh! Yes! The demo that is presented as trial is not working at all. Bad presentation (from the company) of such a good cleaner!..
Summary
It doesnt works!
Anonymous220December 16, 2005
Pros
Too deep scanning, found many errors in my pc.
Cons
Take for 3 hours for deep scanning, it makes "my computer" unable to load, until i used back the Registry First Aid to solve this problem.
Summary
Simply the best registry cleaner available!
Tony63November 18, 2005
Pros
Registry washer might not be the fastest in comparison with other registry cleaner tools, but this tool really took a Ã¢Â€ÂœdeepÃ¢Â€Â scan inside my windows registry and found Ã¢Â€ÂœmanyÃ¢Â€Â errors other tools couldnÃ¢Â€Â™t simply find. From my experience I can say that registry washer was very effective as once I erased the errors registry washer found, my pc ran "at leastÃ¢Â€Â 10x faster. I am very impressed, and that's why I bought it and IÃ¢Â€Â™m now recommending it here for others.
Cons
IMHO I can't see any cons
Summary
good program

Cons
nothing

After identifying the problems that require action, Registry Washer helps you resolve those issues and get your computer back to running efficiently.

But that's not all Registry Washer can do! Registry Washer also includes a variety of other system-maintenance tools to help optimize your computer's performance, including a quick and easy Windows Startup Manager, Registry Defrag, Registry Monitor, Full System Backup, and much more!
