Running Win7 Ultimate, 64-bit. Testing Comodo.
Seems to be working OK, but only tested for a short while, two (2) or three (3) days.
Since it installs as a service, it pretty well overcomes the shortcomings of both live tracking systems and before and after snapshots, at least in theory.
One (1) thing it seems to lack is an inventory page listing all changes for a particular install. There is an inventory page, but it doesn't seem to list everything. It does, however, list registry changes and install location, as well as source location of the install file.
Haven't tested the make install feature, as yet.
The Drivers & Services section does not show either an install or an update date - both would be nice to have - nor does it show an install source, which would make it much more informative/helpful when trouble shooting machine/software issues.
The Windows Features is convenient, I suppose, but no more than a convenience.
No updates since installation, so can't speak to the Windows Updates section.
