Windows: Sometimes it's hard to tell what's really going on in the background while using Windows. The Moo0 File Monitor shows you real-time file changes so you can see what's happening.
The only sign of anything occurring when you're installing some programs is a notable increase in CPU and RAM usage. You can tell your machine is working, but you're not sure what it's doing -- or if it's actually stuck and it's working hard for no reason. Open up Moo0 File Monitor and you can see what files are being created, deleted, modified, or moved, and you can see when it happened. Bonus: see a jump in CPU and RAM usage and you're not installing anything? Open up the monitor and you might catch some malware in the act.
Moo0 File Monitor works on Windows XP and up, is completely free, and can be installed on your system or run as a standalone portable app. Check the link below to download it.
