It may... but it can miss when apps get sneaky or the installation is not correctly done.

REVO trace will remember and remove all the registry entries placed there during a "Traced" install but an application can add to the registry when it first runs after installation. REVO doesn't catch these entries or remove them during uninstall. Thus code remains that can compromise additional installs.

The best tool against this is ERUNT, (Emergency Recovery Utility NT) a free registry backup and restore by Lars Hederer. You can get it here: http://www.larshederer.homepage.t-online.de/erunt/

ERUNT is amazingly fast, taking only two seconds on my 32 bit machine! Thus you can use it in the background to copy the registry without disturbance to whatever is running.

I have ERUNT setup to copy the registry multiple times. It runs at every boot, and I have it automated to run daily at 6PM, and before REVO. Additionally, I have an ERUNT icon on the desktop so it can be run before any install.

ERUNT copies ALL registry entries . Others only get "most" registry entries. I have it configured to save with a filename that provides the date and time (including the second) and a reference to what triggered it. (automated or manual) to assist in restoration. This is easily done using suggestions on Lars web page. (read EVERYTHING CAREFULLY!)

I have been using ERUNT on my triple booter (Linux, XP, 7) for the last six years without failure or error. Highly recommended!
