Q. Bought new Surface Pro 3 with Windows 10. After installing Office 365 and checking the system out I see a yellow exclamation mark over the “Windows (C:) in Devices and Drives. Everything seems to be running properly except:

Wireless internet connection keeps dropping. I have another Surface Pro 3 running next to the new one to check apps, etc and it hasn’t dropped its internet connection.

Windows update freezes with 2 more updates to download and install. Quits at 8%.

Answer.
