Stop A Slow Computer
The on-disc structure of the registry is entirely different on the NT line of Operating Systems (including Windows XP and Vista). Slowdown due to registry bloat is thus far less of an issue in modern versions of Windows. More importantly, however, the difference in speed due to the use of a software registry cleaner is negligible: rarely do they remove more than a few kilobytes from the total size of the registry. Any potential user of a software registry cleaner must thus balance a probably negligible performance increase against a non-zero possibility of system instability.
However, these software registry cleaners are still highly effective and can be used by anyone to better take care of their PC.
