If you really want this Indian Scammer to stop contacting you and asking you about your computer, call Microsoft Windows Support.  Their 24/7 help line is 1-855-698-3249 and explain how rude and annoying this Indian Scammer has been!  I THINK WE SHOULD ALL TALK TO A REAL MICROSOFT WINDOWS SUPPORT ASSOCIATE ABOUT THESE NUISANCE CALLS WHICH CLAIM TO BE THEIR COMPANY!
