Hi,

Thank you for being a part of Windows 10.

I appreciate you for providing details about the issue and your effort towards resolving it.

Try the following methods and check if it works:

Method 1: Perform System File Checker (SFC) scan.

Try to run a System File Checker (SFC) scan to check for any file corruption. SFC scan will scan for corrupt system files on the computer and repair them.

1. Press Windows key + X, click Command Prompt (Admin).
2. In the Command Prompt, type the following command, and then press ENTER:

         sfc /scannow

If the issue persists then follow the below method.

Method 2: DISM Commands. 

Fix Windows corruption errors by using the DISM. 

I would suggest you to run DISM commands from Command Prompt (Admin).

Please follow these steps:

1. Press Windows + X keys and click Command Prompt (Admin).

2. Type the following commands in command prompt one by one and press Enter after each command.

Dism /Online /Cleanup-Image /CheckHealth

Kindly let us know if you need any further assistance with Windows. We are glad to assist you.

Thank you.

I tried all 3 solutions precisely and to the letter, no relief. Here is This PC as viewed from the newly created account:

A new development. Though none of my hard drives are yet visible in This PC, when I plugged in my Android Samsung S5 in, now the Devices and drives category appears:

Just to reiterate, all other drives seem to be configured correctly as follows:

Hi,

I suggest you to place the computer in Safe mode and check if the issue still persists. Safe mode starts Windows with a limited set of files and drivers. Startup programs do not run in safe mode, and only the basic drivers needed to start Windows are installed.

Also perform Hardware Troubleshooter to diagnose issue with hardware if there are any on your computer.

• Type “Troubleshooting” on the search bar.
• Click on troubleshooting, then click on “Hardware and sound”.
• Under Hardware and sound, click on “hardware and devices”.
• A pop-up will appear, click on the “Next” button and your hardware troubleshooting will start.

Hope it helps. Feel free to write to us for any other assistance with Windows, we’ll be glad to assist you.
