I would strongly recommend using trim.bat until I have a chance to update all of my winapp2.ini related code.
does it support “Detect1″/”Detect2″ etc?
It will only check the first Detect.
does it remove entries with valid “Detect” but nothing to delete?
No, it doesn’t parse the FileKey lines at all.
test with installed chrome, all chrome winapp2 entries removed
SPECIAL_DETECT_CHROME is not supported, however Opera (pre-chromium), Firefox and Thunderbird are.
