Installation
Turn off all network adapters even if you set the BIOS date for the machine, otherwise, after the hardware setup, it will automatically adjust to the current time via online time syncing and thus activate the timebomb. This requirement is optional, but not doing this will result in the computer rebooting every two hours. Another way is install this build on the current date, it won't activate the timebomb.

Incomplete "Microsoft Confidential" watermark
In the German-language version, the "Microsoft Confidential" watermark on the desktop is incomplete.
