I'm an IT tech and I use registry cleaning as part of my job. My company advises to use CCleaner, Tuneup and Registry Fix (in this order) as registry cleaning. The problem is that Registry Fix 6.4 does a lousy job. Computers with Bluetooth software or HP printer software get screwed by this utility. It removes some Bluetooth needs entries and I get a btrez.dll error, and also HP printer softwares stops working.
So I want to know if there's any trustable registry cleaner software. CCleaner and Tuneup Utilities are safe to use, no problems caused so far.
Another question is why every registry cleaning software detects invalid registry intems, even if I ran 3 or 4 registry cleaners
