For some unknown reason my SP3 which has been successfully running Win 10 for 9 months, went into airplane mode and it would not let me take it out.
I tried rebooting multiple times, the network troubleshooting tool, and accessing the wireless adapter settings through the Network and Sharing Center which it would not let me do.
Totally dead in the water as far as internet connectivity. Very frustrating.
Other "solutions" to reload Win 10 which did not solve problem for others sounded like a total waste of time and trouble.
So I found this 60 second fix and it worked like a champ!
Thanks a million The Tech Mentor! I was toast and you saved me!
I posted a comment on their website and even received a nice personal reply. Great stuff!
Hope this helps!
