MJ Registry Watcher v1.2.9.1

👉 Monitor and protect important registry keys, files, and startup locations.

MJ Registry Watcher monitors selected registry keys, files, and directories for changes that could affect Windows startup or system security. It combines hooks, which can report many changes as they happen, with periodic polling to catch changes such as registry key deletions. Its monitored locations and response behavior can be configured, and it keeps a log of detected activity.

The program can also monitor process launches and detect DLL injection. It includes registry backup, quarantine, and options for sending alert details by email. The author recommends running it with administrator rights so it can access the registry properly.

How to launch MJ Registry Watcher:
Extract the downloaded files with their folder paths preserved, then open the MJRegWatcher folder and run RegWatcher.exe. The author recommends setting the program to run as administrator: right-click RegWatcher.exe, open Properties > Compatibility, and select Run this program as an administrator. To launch it automatically when you sign in, use Options > Settings > Automatic Startup Options. On Windows 11, this screen also offers startup for all users. If UAC prompts for approval at every startup, the author recommends setting up a scheduled task to run MJ Registry Watcher with administrator rights at logon.

Running MJ Registry Watcher as a service:
With administrator rights, choose Options > Install MJ RegWatcher Service in the program. Before starting the service, remove or disable the interactive version’s automatic startup entry or scheduled task; the service and interactive session cannot run at the same time.

Start MJ RegWatcher Service Stub through Windows Services (services.msc). The service runs invisibly, starts with Windows before anyone logs in, and continues across logins and logouts. It supports Accept and Reject modes; Prompt mode defaults to Accept. To monitor the running service, use mjrwmon.exe, the configured alert sounds or email settings, or the mjregwatchkeys.log file. To remove the service, stop it in Windows Services, open the interactive program, and choose Options > Uninstall MJ RegWatcher Service.
