Nothing quite like the primal rage of being denied permission to delete your own files on your own machine. The classic Windows permission dance: log in as admin, still get blocked, right-click, "Run as administrator," sacrifice a goat, perform a rain dance, and maybe— maybe —Windows will acknowledge your authority. Bonus points when you have to take ownership of files you already own. It's like having a butler who locks you out of your own kitchen because "sir doesn't have the proper credentials to operate the toaster."
