Someone sent you a .reg file? Read it before you run it.

Drop the file (or paste it) and see exactly what it changes — every key and value decoded and explained in plain English, with autostart, policy and hijack locations flagged by risk. Parsed in your browser, never uploaded.

Why not just open it in Notepad?

You can — but raw .reg files hide their meaning well: strings stored as hex(2) byte lists, DWORDs in hex, deletions marked by a single minus sign. This viewer decodes every value type, reassembles the UTF-16 strings, and — the part Notepad can't do — tells you when a key is one of the locations persistence tricks and policy hijacks use. We never stamp a file "safe"; we show what it does so you can decide.
