Windows 10: Remove All Devices Under Manage Mobile Devices

I want to reset my manage mobile devices but I can't remove my old phone or new phone. I think having both was causing me problems with double messages. How can I remove them? There is no option at all. I have removed the Link To Windows program from both phones, however the Pixel 7, I removed it by resetting the phone back to factory default. Pixel 9 I did sign out of Link to Windows, however it still shows here.

No hardware listed in Device manager?

I don't konw whathappend but in Device manager and in my Network connections there is nothing where there used to be a Modem listed and all my hardware in Device Manager. What happend and how do I fix this?

 

Remove 'Mobile devices' From Task manager>Startup apps

From admin PowerShell, run:

• get-appxpackage -allusers *crossdevice* | remove-appxpackage
  

This removes the Mobile Devices startup entry.

Device Manager Un-Hiding Hidden Devices

When you connect a plug and play device, Windows Plug and Play manager detects it, finds and installs the driver. Device Manager lists the device with a solid icon.

The driver is only removed when you uninstall the device, not simply by disconnecting the device. When the device is disconnected, its driver is still installed. By default, Device Manager only displays connected devices. When you show hidden devices, note the Bluetooth icon you see is semi-transparent (not opaque). That indicates a "non-present" device. Sometimes also called a "ghost" device. The driver is still installed but the device is not currently detected (i.e. not connected).

Device can be disconnected when

• Device unplugged (e.g. removing a USB device)
• Turning a device OFF
• Disabling the device in BIOS (then windows won't detect it) or
• Device failure

So

• Check BIOS as suggested
• Check board connections
• Can b/t be turned off by a switch? or keyboard combination?

Also possible the b/t h/w failed
