Troubleshooting

Problems with Windows 10 activation

The copy of Windows 10 used at Imperial is a volume licence, which automatically activates everyone's licence on the Imperial network. The trouble with this approach is that devices not on the Imperial network, e.g. home workers in lockdown, aren't on the Imperial network and so the licence deactivates as a precaution after three months away.

As you can tell, this will start happening to everyone at Imperial three months after lockdown. Which is now (early July).

How to fix it and get Windows 10 activated again

The fix is very simple if you follow these steps exactly.

1. Connect to the Pulse Secure VPN temporarily.
2. Press your Windows 10 start button (bottom left).
3. In the Windows 10 Start Menu, type: cmd
4. Your Start Menu will show a black icon with "Command Prompt" next to it.
5. In the right pane, click on "Run as administrator". A black window will pop up.
6. In the back window, type: cscript slmgr.vbs -ato and press ENTER.
7. The command will run and after a few seconds you should see that Windows is successfully activated.
8. Close the black window.
9. Disconnect from Pulse Secure VPN.
