Hi and thanks for reaching out. I'm Gokul, an Independent Advisor. I'll be happy to help you out.
I understand that you want to restore the disabled desktop icons on your computer.
Please follow the below steps to restore the icons.
Right-click on your desktop and select "View" from the options -> Verify "Show desktop icons" is checked. If it's unchecked, click on it to enable it.
If This PC or Recycle Bin ( Default application) are missing, right-click on your desktop and select "Personalize" -> Click on "Themes" on the left-hand side -> Scroll down and click on "Desktop icon settings" -> Now check the boxes for the icons you want to display like This PC, Recycle Bin, etc
Click "Apply" and then "OK" -> Now your icons will be restored.
I hope this information helps you. Kindly let me know if you need further assistance. Thank you!
Regards
Gokul
