There is actually just one problem, it's not stable.
On Windows 10 RS1 I get 1 or 2 app crashes a week, well actually that great for everyting that comes after Windows 7.
However on this new RTM, I have crashes every couple of hours.
Left alone the hidden ones, you only noticed looking at the event log.
Specially explorer hangs and crashes are very annoying.
On ADK side they messed up the wofadk.sys driver, it can no longer works under Windows 7. Just like they did with bcdedit.exe.
Also you properly noticed the system context menu "New" sub menu in the new WinPE.
Well, it freeze because it now depends on the StateRepository service.
We can get it to work on WinPE, but will need a workaround because it 's not fully compatible with the FBWF used in WinPE.
