RegTool performs registry scans significantly slower than most other registry tools. This is not necessarily a bad thing, as it seems to work very thoroughly to detect every invalid entry.
There are a number of things that RegTool detects on every system and it breaks it all down into categories: registry, junk files, privacy, bad ActiveX, optimize PC and Microsoft updates. Each of these categories can range from a few detections to hundreds of them, this addresses every aspect of your PC that needs attention.
This tool has a wide range of options to get your system optimized, though it does work slightly slower than most other tools.
System crashes, system freezes, slow computers, runtime errors, active-x errors, browser errors, hhctrl.ocx errors, dll errors, slow starts, slow shutdowns, dr. watson errors, blue screens of death (BSOD) etc.
