I did see a SP3 review that had a nice list of apps but cannot find that article. One app I would like is a cleanup tool to get rid of stuff that I uninstall completely.
I've used AppZapper on the Mac with great success. Any recommendations for Win8?
Check out CCleaner (formerly Crap Cleaner), https://www.piriform.com/ccleaner/download
Once you install it, select "registry cleaner" from the left-hand navigation. Do several passes until it doesn't find anything else.
