Windows 10: USB flash drive(s) not showing in File Explorer

I believe this started with the 720 (1909 18363.720) Windows Update but I'm not sure. I'm going to try backing out the latest WU in a bit but wanted to post the problem here before doing so.

File Explorer is not seeing any USB Flash drive or mounted ISO, but I can look at them if I enter the drive letter directly in File explore:


I have a Win10XPE Rescue flash drive inserted and it has been assigned drive I:
Code:

File Explorer doesn't see it.





If I enter I: directly in File Explorer address area it shows correctly:

USB Flash drive made bootable

Hi Nelson,

Check if there is any slide switch on the side that provides write protection. It show's a closed and open lock on each side. We suggest to follow these steps below:

• Insert the USB flash drive into the USB port.
• Click Start, type devmgmt.msc in the Search textbox and press Enter.
• Find Disk Drives and expand it.
• Find the USB flash drive you want to format, and double-click it. It opens the
  Properties dialog box.
• Click Policies tab.
• By default, the Optimize for quick removal option selected, switch it to Optimize for performance and then press
  OK.
• Now open Computer. Right click on the USB Flash Drive and select Format. The Format dialog box now appears.
• Select NTFS in the File System field.
• Press Start and wait while the process will be completed.

You can also connect the USB drive on a different computer and try formatting.

Let us know how it goes.
