Thanks, but the post explicitly says: Set_OpenInTC_Item.cmd
So this would clearly indicate the code to follow being a .cmd-file. A registry-file on the other hand should have the extension ".reg" and wouldn't it need to say
"Windows Registry Editor Version 5.00" right at the top?
Addendum:
These code sections also start with: "@echo off". Never seen that in a .reg-file.
