Using CCleaner

How safe is it to remove what ccleaner finds. I have a bunch of Invalid Uninstall Ref. items a lot of it is Microsoft Q37654 type things.

 

Those entries should be safe to remove, but I don't entirely trust Ccleaner. Making backups is essential, in my experience.

 

Thanks you all.

 

I started deleting those items found in Issues category by category. Now I have nothing to delete. But I monitor my system for nearly a month or more before I even started deleting those found in Issues. (by the way I back up every item I deleted)

Say if you want to delete those Invalid Ref then you better delete all of the Invalid Ref found together but make sure you make a Back Up of all of them before you delete them.

Then use you pc for a week or two and trying out everything. Monitor if there is anything weird going on.

If everything is fine then you move on to the next category. Make a backup and "Fix Selected Issues". Wait and monitor your system for two weeks testing out everything.

So if anything weird happens you can restore those deleted Registry items. I do that all the time. Delete and restore then delete then restore.

In the end I just delete them all ...

So far so good. Everything remain the same.

Hope that helps.

 

Thanks Chew.
