Iīve been "playing" with these four registry cleaning tools and have made a few observations. To give them something to look for, I uninstalled Norton System Works and removed all left-over folders from the system partition. In each case I only run the search but didnīt take any action to clean.
You best stick with Regcleaner. If you use Jv6 better be careful!
Well, Iīve been a good lad for a long time so, I thought it was time to be naughty. I run the jv16 PowerTools RegCleaner (referred to as jv16 to avoid confusion), as well as RegCleaner to compare those two.
My finding is that jv16 finds twice as many green items as RegCleaner finds invalid entries, 90 compared to 45. In addition to that, it finds 183 red items compared to 10 ignored entries found by RegCleaner.
RegScrubXP found 64 problems and EasyCleaner found 109 invalid references.
When I started actually cleaning the registry, I always did one run in this sequence, RegScrubXP - EasyCleaner - RegCleaner - jv16. I found out that the first round of cleaning, released a bunch of new invalid entries. After a few runs this was left:
RegScrubXP - 2 problems (which returned each and every time, recreated?)
EasyCleaner - 0 invalid references
RegCleaner - 0 invalid entries, 9 ignored entries
jv16 - 0 green, 51 red
This means that RegScrubXP and EasyCleaner removed 132 entries which jv16 deemed not safe to remove.
Is jv16 overly cautious?
Among the 51 reds are 28 referring to Norton or Symantec. I wonder if those would be safe to remove since the application has been uninstalled?
When I deleted a number of files, *.txt and *.doc, RegscrubXP and EasyCleaner found nothing whereas RegCleaner and jv16 found quite a few invalied entries. Again, jv16 found twice as many as RegCleaner.
Could it be that jv16 lists the same key twice if it is in two sections of the registry but RegCleaner only cares to mention it once?
I have not (yet) used or studied any of the other functions of jv16 PowerTools!
