After reinstal, Windows hangs at activation
Problem: After clicking OK at this error message, nothing happens, Windows hangs at background screen
Error messages states:
Windows Product Activation
A problem has prevented Windows from accurately checking the status of the license for this computer. To proceed your copy of Windows must be activated with Microsoft.
Do you want to activate Windows now?
Problem was network switch which works fine with other PCs, however with this one it was not operative even though it looks like everything's ok with network (blinking at network card, connecting another PC). Windows do not offer user to see network status on PC, or workaround with this message (by unplugging network cable) thus user can't see that network card reports error because drivers list is unavailable. It seems that the card had problem with network speed in relation with the switch.
It was solved by simply connecting PC to another network switch.
