Update history shows 17 failed instances of Microsoft attempting to upgrade my Surface Pro 3 to Windows 10. Error code 80240020 is given as the reason, but there is nothing listed for this error code at the Microsoft knowledge base. I do not want to upgrade yet - not until they sort out the bugs. Anybody know how I can stop these attempts? They are making my Surface buggy while they are going on. I jumped ship from iOS because of stuff like this!
