Unwanted software on a PC can be a problem for various reasons.
1. You install a program and it doesn't work or doesn't do what you wanted.
2. You want to update a program you already have installed, and after installing a new version, it doesn't work properly. Or, the new version tells you to uninstall the old version first.
3. You like to try different programs, and your Start Menu is overflowing and your PC is getting slower and slower!
4. After a year or more, your PC is slow and it sometimes freezes or crashes for no reason, or when you try to run a specific program. (Note that this can also be caused by a virus or other malware, or something has damaged your windows installation).
Unfortunately, most programs simply use the standard uninstaller that comes with windows (or none at all). This will usually leave some or all of the program behind and simply remove the Start Menu link, or will delete the program from the disk drive, but leave a lot of entries in the Windows Registry that becomes bloated and slow over time, and many other issues.
I have tried several '3rd Party' (which simply means that it didn't come with Windows or from Micro$oft). and have found some to be good, and some just make things worse! The good news is, my favorite is completely FREE!
Before you use it, make sure to take the time to read the information on the website and the included Help.
It's called Revo Uninstaller, and the website is:Revo Uninstaller
I will post other good free software as and when I can.
