Game crashes

ViciousMegZ​  You will want your antivirus enabled (Windows Security if you don't have anything else installed), and the sound driver (Intel or Realtek, probably) if it's there, but pretty much anything else can be disabled.  These apps will all open as normal if you decide to run them; they just won't do so on their own.  Plus, this is entirely reversible—you can reenable whatever you want if you change your mind.

More importantly, the services that are crucial to Windows or other essential functions, for example the graphics driver, won't appear here.  So you're not going to prevent your computer from working.

If you like, you can post a screenshot of the Startup list and I can look it over.
