I think the main argument here is with running registry cleaners on a regular basis as part
of general system maintenance vs using one when all else fails.
If there is no known problem using a 'cleaner' does not improve performance.
If you are faced with a reformat, or even a 'repair' reinstall then a running a
registry cleaner is a viable option.
Curious - When you installed the registry cleaner did you do anything else such as run Disk Cleanup
and defragment your HDD, or did you do nothing else but download, install and run the cleaner ?
Did using the cleaner make you aware of which of the registry entries were causing the lag ?
[ EDIT: @ T-Bone - Doing a System Restore will delete any registry entries that result from a
failed install.
It's more fail-safe as it will delete only the registry entries that resulted from the failed install.
- Of course you could also run a registry cleaner and select only the entries that relate to the
suspect program to delete, and leave what you aren't positive about.
This is generally easier than browsing the Registry . ]
