Some more details on the workaround:
In the screenshot above, it can be seen that the words CLOCK$, AUX etc. are presnt in the ntio.sys file shown in the right pane
Now, when you select a character like 'C', the corresponding hex vaule i.e. 43 or more specifically 0x43 is selected on the left side. Now change this vaule to 00 or null for every character and create the workaround.
This can be done with any Hex Editor worth its salt or even with VC++
