Has this happened to you? Tired of Windows crashing? Sick of having software lock up on you or taking forever to load? The problem could be all of those incorrect registry entries caused by software installations and un-installations that went awry!

With regular use most personal computers develop large numbers of registry errors that degrade perfomance and cause error messages and/or crashes. The Boot time (start-up) is profoundly affected by a clogged Registry slowing things down. By using a registry cleaner like Registry First Aid regularly, your system will not only be more stable but it will also help improve your system perfomance without expensive hardware upgrades.

As a pioneer in registry repair and maintenance for more than ten years, Registry First Aid, developed by Rose City Software, has a long track record of finding more problems than any other registry repair program on the market. Don't be fooled by the dozens of new registry repair programs you find when searching the Internet. It takes years of fine tuning like Registry First Aid has. You won't find this in clones created for companies that throw together a quick registry program just because they have seen the success of Registry First Aid.

Weekly use of Registry First Aid completely eliminates poor performance.


"Of all the registry tools I've had, none can compare with your software. I really wouldn't want to be
without it. It keeps my computer running like new! Great value for money."
Don Brummie

"During my 25 years as a computer professional Registry First Aid is one of the few 'no nonsense tools' I've been using. That is, it does exactly what it's supposed to do - without any need for additional parameters or knowledge. Hence, the term 'no nonsense tool'. I'm going to recommend this program to my associates, customers and friends.".
Geir Strom Pedersen, Project Management Graduated Engineer

Time Tested

Registry First Aid, developed by Rose City Software, is one if the first registry repair tools available and with years of fine tuning has evolved into a world class program to keep your computer tuned for high performance.

Easy and Fast to Use
We listen to our users... With Registry First Aid, you have an easy to use step by step interface design that has been fine tuned with input from hundreds of thousands of users making it very effortless to use. Speed is essential with our high-performance detection algorithm that quickly identifies missing and invalid references in your Windows registry selecting them for correction or deletion.

Safe for Beginners
By flagging problems in the registry with the green, yellow and red safety levels, you know which problems you can easily correct yourself. You will find that the clones such as the ?one click fix? models and others will just plow through the registry and delete many required entries. Don't let that happen to you!

Experience always improves performance, and Registry First Aid has that with years of experience in detecting and correcting problems. In side by side comparisons, Registry First Aid has always found more problems than the competition.

Complete Built-in Backup System
Before running, Registry First Aid will make a Restore Point or backup of your registry. When the registry corrections are made, a complete backup of all changes made is save and you can restore the registry to the way it was before you started as well as individual registry entries in case of a problem. This is another feature not found in many of the new programs on the registry repair scene.
