I deleted the following Registry key and encountered a lot of problems after restarting the computer:

HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache\Tree\Microsoft\Windows
  • For example, I cannot type anything in Windows Search, sound does not work correctly, with the worst thing being System Restore doesn't work no matter what I do.

How do I fix this?

When a number of things go wrong from an error as happened here, the best thing to do is a Windows 10 Repair Install. There are 3 ways to proceed:

  1. Keep Everything - best if it works and your computer comes back just the way you had set it up except repaired.

  2. Keep Data - necessary if the operating system damage is extensive. Keeps the User Profile and makes software install quite easy.

  3. Keep Nothing - deletes the User Profile and all else and is essentially a fresh install. Necessary if the User Profile is damage. Be sure you have backed up all your data.

Windows 10 is running, so click on the Download button (not Upgrade Button) and select Run. If the Repair will not run as per above, use the Download button to create a USB Windows Installation key, then run Setup on the USB Key.

This will launch the Repair and proceed normally.

Start with the option to Keep Everything.

You can also Keep Data, or Keep Nothing. Keep Nothing is very close to a clean install.

If System Restore is enabled, rollback to a save-point from before this registry update was done.

For more information, see the article How to use System Restore on Windows 10.
