Yesterday Microsoft has released more than regular updates for windows defender. Into the list was two or three updates regarding security updates for Windows Developer Preview and after i was allow them after reboot the text into the picture posted above has showed again on the desktop (instead yesterday update only .b32615... was there). I was try the tool to remove the Microsoft text but is still there after the tool has reboot my computer. Also the winver has been changed...
TBH, and this is my own personal point of view I cannot see the need to hide a watermark on any pre-release software. It's like showing your fake Rolex to your friends and family.
for me; i like to remove watermark text but not to fake my self or my friends but because its ugly and useless text, that is the point
