I haver used Revo Uninstaller for years, without any ill effects. Create your own manual restore point before each uninstall as although Revo does one, it just says "Revo" with no other info. I select the 3rd radio button for uninstalling, When you get a tree view list, always expend every + sign and only tick item that are listed in BOLD.
There are other tools, including a very useful startup manager.
I do not recommend CCCleaner or programs that modify system files to optimize the computer.
From PC "This is a good time to kill anything you don't want that's part of Windows 8 itself. Load up the control panel called Uninstall a Program (search for it from the Start screen). On the left, click "Turn Windows Features on or off." You'll get a User Account Control warning; click OK. Uncheck anything in the list you definitely don't want, such as games, Tablet PC Optional Components, etc. If you don't know what an item does, hover the cursor over the name for a description. If you still don't know what it does, best to leave it."
