My personal opinion is not to use registry fixers. If you google it, you will find mixed reviews.
BC's stand is the following...
Bleeping Computer DOES NOT
recommend the use of registry cleaners/optimizers for a several reasons:
Registry cleaners can damage the registry by using aggressive cleaning routines. Many users (including some Staff Members) have reported problems after using registry cleaning tools - to include those tools released by Microsoft. This can cause your system to become unbootable.
Registry cleaners generally don't do anything significant for your system. This topic discusses it in greater detail than we could address here: http://www.windowsbbs.com/showthread.php?t=61015
Although the topic discusses the XP registry, the concepts there apply to all other versions of Windows.
Not all registry cleaners create a backup of your registry before making changes. If the changes prevent the system from booting/logging in, then there's no backup to restore in order to regain functionality. A backup of the registry is essential BEFORE
making any changes to the registry.
