Pinning Word File to Taskbar

There is no need to Take Ownership of the file??
Just follow the instructions in the link in post #2 You just need to change the extension of the file name temporarily till you pin it to the taskbar. then rename it back to the original extension.

You don't need to do this for what you are trying to achieve in this thread, but if you want to add Change Owner to the Context menu, instructions are here Add Take Ownership to Context Menu in Windows 10

?? You are not following the instructions in the link. Pin File to Taskbar in Windows 10 Please read it, it also has pictures.
Let me surmise; In File Explorer, you are going to the Toolbar to View you want to put a check in the Box For Hidden Files and for File Name Extensions. With File Name Extension checked you now should see the File Extension of the Word file (ie) FileName.doc Right click this File and choose Rename Rename this files Extension to .exe (ie) FileName.exe. Now Right click this file and choose to Pin to Taskbar. This will create a shortcut to the file in the Taskbar. Go back to where the original file is and Right click it and choose Rename then Rename the file to the original extension (ie) FileName.doc Go to the shortcut on the Taskbar and right click it and choose Rename and rename it with the original extension (ie) FileName.doc
