I use InCtrl5. The following is taken from the Help File:

--- CUT HERE ---
InCtrl5 records a "snapshot" of your system before the install utilit=
y=20
runs. Afterward, it records another snapshot, compares the two, and=
=20
reports the differences in HTML format, plain text, or comma-separate=
d=20
values format. Click here for help with the program's main form, or h=
ere=20
to learn about the process of tracking an installation.

InCtrl5 is the fifth incarnation of one of PC Magazine's most popular=
=20
utilities, and naturally has a number of new features. InCtrl5 was=
=20
designed for and tested under Windows 95, Windows 98, Windows ME,=
=20
Windows NT4, and Windows 2000. Unlike InCtrl4, it does not support=
=20
Windows NT 3.51. It will not run under any any other operating system=
 -=20
if you try, it will warn you of incompatibility and all of its contro=
ls=20
will be disabled. If that happens, check the PC Magazine web site to =
see=20
if an update is available.
