Tiny Watcher will monitor/track changes on your Windows system, including files, registry, running processes, and scheduled tasks.
It takes a snapshot of these areas, then tracks changes that have been made. Tiny Watcher will alert you if a change is found and whether the monitored item was created, modified, or deleted. It can be set to run whenever you prefer, like when you log in, etc. Once you run Tiny Watcher, it performs its scan quickly. Of course, this will depend on the number of items being scanned.
Tiny Watcher can also be customized to suit your specific area of interest - registry, files, tasks, etc. It utilizes the SHA-256 hash for detecting changes in files. Tiny Watcher is another simple means for protecting your machine through a straightforward UI that allows you to keep a watchful eye on changes to various bits of system info that could point to a security issue.
