My current keys for Office 2013 and Windows 8 Pro were blocked for some reason (I got them from an educational program). I activated both office and Win8 Pro using a tokens.dat and Data.dat backup from when it activated successfully (After installing the backup files it works). I have successfully installed all of the Windows updates and now have the option to install Windows 8.1 Pro using the store. If I do so, will I still be activated?
I think there will be a chance that you will be still have an activated Windows after upgrade but a high chance to have a deactivated office after upgrade. My computer have Win 8 Pro WMC with MS Office 2013. After upgrade from the Store Windows 8.1 Pro WMC is still activated yet MS Office 2013 got deactivated. Luckily I got a key(MAK) for the MS Office 2013 and Activated it using it.
