text: Almost without exception, after you delete a program, there are remnants files and registry keys left behind.  In most cases, these files are benign and can be deleted.  However, there are cases in which these are needed by other programs on your computer (eg. shared DLL's).  Deleting these files might cripple these programs.  The safetest thing to do is to create a restore point before deleting them.  If you notice, after deleting, your system is behaving strangely, then you can restore your computer to an early time.  My other suggestion is to try a uninstaller software program.  There are many commerical and free uninstallers available.  These programs delete the undesired program and any files associate with it.  In regards to commercial products, Iolo's System Mechanic is the best I've used thus far. Other good choices include: Symantec Norton's System Works and TuneUp Utilities 2006.  You can find.  However, in regards to free uninstallers, I haven't found any that are on par with the commercial ones.  But, there are some decent ones, including: Easy Uninstaller, MyUninstaller and Zsoft. You can find these items on www.betanews.com.\n\nOn a different note, i recommend you use Disk Cleanup periodically.  To get more hard drive space, consider decreasing the size of the recycle bin and restore points.
