No, it does not shutdown every two hours. This is what happens:
Reminders and Limitations
- The first reminder you'll get will probably be an Action Center tooltip in the Desktop Mode:
You can safely ignore this tooltip and nothing bad will happen. - Another reminder you'll probably see quite often is every time you open the PC Settings screen. When you do, you're greeted with a new section:
Again, you can safely ignore this and click any other settings section on the left-hand side of the screen. Except that... - Personalisation settings section is disabled:
The disabled settings include:
- Your lock screen wallpaper and apps
- Start Screen colour and background
- Your account picture
You need to activate Windows before you can personalise your PC.
I heard there are some workarounds for this, but as this was not a part of my experiment, I will not describe them here.
- Every couple of hours, you'll see a full-screen activation request:
To dismiss it, you have to click Go to PC settings and then you're back to the screenshot from point 2. Still,
you can exit this screen normally, with or +, or any other way you like. I wasn't able to pinpoint the exact frequency with which this overlay appears, but it's certainly more than 5 hours and less than 7 hours, so I guess
it appears every 6 hours. - When you try to enter a command to show the status of activation:
You get a not very informing message, saying that Windows is in Notification mode:%windir%\system32\cmd /c slmgr/xpr
EDIT: As vhanla notes in the comments, if you run:
you'll see:%windir%\system32\cmd /c slmgr/dli
Name: Windows(R), Professional edition
Description: Windows(R) Operating System, RETAIL channel
Partial Product Key: XXXXX
License Status: Notification
Notification Reason: 0xC004F009 (grace time expired)
But even though the grace time is already expired from the start, Windows continues to work correctly.
So... I guess that's it. There are no other differences from the activated copy of Windows 8 Pro that I found. Of course, because I didn't enable Internet access, online-related activities like installing new apps from Windows Store or obtaining system updates obviously don't work. TL;DR
- You can install Windows 8 Pro without an Internet connection
- Windows 8 Pro without activation is usable
- There is probably no time limit for activation of Windows 8
- You'll get occasional reminders to activate, but they are safe to ignore
- The only thing that's disabled is Personalisation Settings screen.
