Safely Remove Hardware tool

Thank you for the update, Murray. Since you mentioned that you've already tried running the rundll32.exe shell32.dll,Control_RunDLL hotplug.dll command to no avail, we suggest that you create a shortcut or even a batch file using the same command. Just run
the shortcut or batch file and see if the Safely Remove Hardware dialog window will appear. To create a shortcut, follow these steps:

• Right-click on the desktop and click on New > Shortcut.
• In the Type the location of the item box, type in, or copy and paste the following command:
  • rundll32.exe shell32.dll,Control_RunDLL hotplug.dll
• Click Next and then give it a name like Safely Remove Hardware, and then click on
  Finish.

Keep us in the loop.

Try the methods below and check if it helps:

Method 1: I suggest you to boot the computer to Safe Mode and check if the issue occurs or not. If not, I would suggest you to set the computer in a clean boot state and check if it helps.

Step 1: Boot the computer to Safe Mode. In Safe Mode computer starts with
minimal set of drivers and files.

Step 2:
If the issue do not occur in Safe Mode, perform a clean boot and check. Setting the system in a clean boot state will help to identify if any third party applications or startup items are causing the issue.

If the issue persists, try this:

Method 2: I suggest you to perform SFC (System File Checker) Scan from Safe Mode and check if it helps. SFC scan will scan for corrupt system files on the computer and replace them.
