registry monitoring tools

I need to monitor the changes of my computer registry changes because I am testing software installation process.

here are good links for these tools:

1. RegMon for Windows v7.04. this is outdated tool.
2. Process Monitor v3.2
3. DiskMon for Windows v2.01
4. this is a good link.

   You will find an open source tool to compare the difference of registry at different state. please download from regshot

5. a registry manager software is good to try too: Registrar Registry Manager 7.

it turns out the regshot meets my need easily.
