I need to uninstall the alpha to make room for the beta, where is the directory that it installed to? I tried uninstalling using the Settings apps tab, but my disk space did not change, so the files are still on my hard disk and it looks like I need to delete them manually. I am on Windows 10.
UPDATE: I noticed that this post has been viewed 15.2k times, which tells me that a lot of people are having issues. For anyone reading this, scroll down to the posts by @ufotinik and @clarkalii they provide the info necessary to handle this problem.
