2. Open the Registry Editor.
3. Click the plus sign next to HKEY_LOCAL_MACHINE
then SYSTEM
then CurrentControlSet
then Control
then click FileSystem
4. On the right side, double-click on NtfsDisable8dot3NameCreation and give it a value of 1. Click OK.
5. Close the Registry Editor.
Disable 8.3 filename support for current files

Ok so you disable 16 bit legacy names so now how you gonna run some real useful apps like that rely on 16 bit names ?
I would say you are telling people to give up stability for a very minor increase in speed
