Modern setup host

Hi Hermie,



Regarding your concern with the deleted Modern Setup Host file, we’d like to ask the following questions so we can isolate it at the same time:

• What particular action that you’re trying to perform at the time that it was accidentally deleted.?
• May we know where and how it was deleted on your computer?
  
• Were you able to check if the deleted file can be found in the
  Recycle bin?

As an initial step, we suggest that perform a DISM command. This will help repairing possible system file corruptions. Follow these steps:

• Type command in the search box.
• Right-click on the result and select Run as administrator.
• Type this command: DISM /Online /Cleanup-Image /RestoreHealth
• Press Enter.
• Close the Command Prompt windows and check if changes were made related to the Modern Setup Host file.

We'll wait for your update after trying the steps.

Saving and deleting files

I suspect you have some agent that interferes with the normal operation of Windows. Please try this to find out:

• Press Shift+Restart to start Windows in Safe Mode.
• Modify some file, then save it.
  
  Delete some file.
• Press Shift+Restart to start Windows in Safe Mode.
• Check if the actions from Step 2 persist.
