Open up regedit.exe and head to the following key, creating it if the key path isn’t there:
Once you are there, create a new 32-bit DWORD on the right-hand side named VerboseStatus, giving it a value of 1.
Now when you start up or shut down, you’ll see more verbose messages telling you what is taking so long.
I have created lazy way to do it, just copy the code below:
Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System] "VerboseStatus"=dword:00000001
Save as .reg file and run as administrator as we need to edit the HKLM.
I have tested this on Windows 7 SP 1, Windows 8, Windows 8.1 and Windows 10 version 1607 (Anniversary Update)
