Identify mystery apps installed on your PC
I'm always looking for a little bit more performance from my PCs, so I regularly use Piriform's free CCleaner utility to clear out the clutter on my systems' hard drives. (Note that CCleaner is donationware, so if you find yourself using it regularly, drop a few ducats in the virtual coffer.)
The last time I ran CCleaner on my XP test machine, it freed up almost 2GB of hard-drive space by removing temporary Internet files, sweeping out the Recycle Bin, and deleting various Windows updates and other system and application files I no longer needed. Then I clicked the program's Tools option to view the applications installed on the PC.
Use CCleaner's Tools options to view the programs installed on your PC, and remove those you no longer need.

CCleaner wasn't any help identifying the programs, nor was XP's own Add or Remove Programs applet. After searching the Web for both "otto.exe" and "ps2.exe", I figured out that the former was a game that accompanies Windows Media Center Edition, and the latter was a keyboard utility from the PC's vendor, HP.
That was all I needed to know to decide that Otto could go, but PS2 should hang around lest I someday plug in an "enhanced" keyboard and might actually want to use the specialty control buttons on the top row. These are the buttons that let you open apps or your favorite Web pages, control the PC's volume, and perform other system operations, such as putting the system into sleep mode.
It would be nice if Windows provided some clues about the programs it lists in XP's Add or Remove Programs and Vista's Programs and Features. For example, Programs and Features on my Vista system lists the Viewpoint Media Player, but it offers no hint as to where the program came from, apart from the date it was installed. From what I was able to gather after a Web search, the utility is related to the display of 3D effects in AIM.
Since I use Trillian and Google Talk for my IM sessions, I don't need the Viewpoint player. A bigger question is how the program got on my PC in the first place. It didn't come preinstalled on the machine, and no other programs were loaded on the same date as it was. Still, the next most recent software installation was AIM itself, which had an installation date one month later than the Viewpoint player.
However the program managed to slip onto my PC, removing it freed up more than 7MB of hard-disk space. At least the Viewpoint player wasn't in my auto-start list. I'll take a paring knife to that roster in a future post.

@2,3 I agree, not any help here...

(6 Comments)Well if no one else wants to recommend some tools for this, I guess I will:
Glary Utilities; http://download.cnet.com/Glary-Utilities/3000-2094_4-10508531.html?tag=mncol
In my opinion, more powerful than CCleaner. Does all the usuals but also contains a nifty process manager that shows all active processes and their executables, with options to permanently block them. Also has an online database with file ratings. This can also be accessed through the Startup manager.
The uninstaller is quick and clean, allows batch uninstallations, and can fix invalids. New programs gain a 'New!' suffix so they can be identified.
It has a Pay and a Free version, but to be honest, the pay version only unlocks auto-scans and auto-updates. Both I prefer to do manually.
