Put the 3 batch files somewhere on your Desktop.

cache.bat

Use this to create/renew the cache. Depending on the number of files on your drives and the number of drives this might run for a few minutes.

If you prefer it would not index certain drives, remove the letters from the list.

Create the two files below. Keep whitespace as is. You can now use the Task scheduler (taskschd.msc) to create an update schedule that fits your computer usage. Microsoft usually publishes updates on the second tuesday of every month unless they are extremely critical. The files need to be run with administrative privileges.

//Params:
//cb - required(function), called on complete sequence with all 3 parameters
//check - optional(function), checks if key presses should be evaluated, called with all 3 parameters.
//single - optional(bool), if set to something that evaluates to 'true' the secret can only be used once.

You can’t perform that action at this time.
