How to turn off Flight Mode on a desktop PC

Hi, I guess you've researched this apparent absurdity:

Ideas posted:
1. Go to your FN button and your Print Screen Press them both together and hold them Both Down together then go to your print screen and delete it then go to your airplane mode and turn it off it work for me and it should work for you airplane mode is off.
but desktop keyboards don't usually have Fn buttons

2. If you have a UPS attached to your machine with USB, that can cause Windows 10 to assume you are on a portable device and thus require Flight Mode.

Disconnect you the USB connection to your UPS (if any)3. Use Powerchute: Quite often in your scenario the Airplane Mode bug is triggered by having a UPS data cable connected to your computer. In that circumstance Airplane Mode can be removed by either unplugging the data cable or installing the UPS data management software (eg. -Powerchute for APC, etc. etc.)Comment by some this didn't work

4. Registry

Here I offer this as possibly useful info. If I turn Flight mode ON on my laptop, this is the change I see in the registry during the monitoring period:
Flight Mode.zip
I suggest the entry
HKLM\SYSTEM\ControlSet001\Control\RadioManagement\SystemRadioState\: 0x00000000
HKLM\SYSTEM\ControlSet001\Control\RadioManagement\SystemRadioState\: 0x00000001
may be of interest.

As to its relevance or existence in a desktop, I can't comment, but you could, cautiously, experiment.
