the webpage confirmed that getting MSRT via Windows Update does not install any menu items. MSRT "runs in the background". So I downloaded the UI version and ran what I thought was the install file.
The install file did not show a typical installation window. Instead it showed a scanning window with options for a Quick Scan, Full Scan, and Customized Scan (for a specific folder). I did a Quick Scan and it found nothing. This file appears to be a self-extracting file that doesn't install into any directory or onto the Start menu.
This also creates a log in %WINDIR%\Debug\mrt.log.
MS says the definitions for this program are updated the second Tuesday of every month, but the program does not have a menu bar or any way to get new definitions. I assume one has to download the new program from MS Update every time. So, date your exe files when you download them.
And it does not look for the TDSS rootkit, which is what I had recently on my home PC.
EDIT: Here we go. MS says you must download a new version of the tool after they updated it.
