===== Windows 11: Restore 'New Test Document' to context menu =====
Sometime in March 2023, the option to create a new text document disappeared from the Windows 11 context menu (//Right Click Menu//). Here's one way to replace it that I know works as of 2023/04/06.

(First backup the Registry.;-))

  -  Open regedit.exe
  -  Expand ''HKEY_CLASSES_ROOT'' and look for a ''.txt'' key. If none exist, create one.
  -  Within the ''.txt'' key, create two new Strings: ''Content Type'' and ''PerceivedType''.
  -  (Right click) Modify... and the value for ''Default'' should be ''txtfile''.
  -  (Right click) Modify... and the value for ''Content Type'' should be ''text/plain''.
  -  (Right click) Modify... and the value for ''PerceivedType'' should be ''text''.
  -  Create a new key with the name ''ShellNew'' within the ''.txt'' key.
  -  Within the ''ShellNew'' key, create a new **String** with the name ''NullFile''.
  -  Within the ''ShellNew'' key, create a new **Expandable String Value** with the name ''ItemName''.
  -  (Right click) Modify... and the value for ''ItemName'' should be ''@%SystemRoot%\system32\notepad.exe,-470''
