Microsoft never make it simple. I purchased a windows 8 upgrade for 25 quid to upgrade my existing windows 7 install. However my SSD with win7 on it died so I installed windows 8 onto a new SSD. But then windows wouldn’t activate as it was a ‘clean install’ rather than an ‘upgrade install’.  Seems like this is a common problem but easily sorted

• Open regedit by pressing Windows-q, entering regedit and selecting the result from the list of hits.
• Navigate to HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/Setup/OOBE/
• Change MediaBootInstall from 1 to 0
• Go back to the start screen and enter cmd there.
• Right-click Command Prompt and select to run it as administrator.
• Type slmgr /rearm on the command line and hit enter.
• Reboot Windows now.
• Run the activation utility afterwards, enter your product key to activate Windows.

Tried watching some tv episodes streamed from my WHS box and found them stuttering really badly – first time ever doing this. Logged into WHS and found one drive completely full with half a terabyte of ‘client pc backups’. Did some googling and found out how to remove safely the unwanted ones and freed up the necessary space

here is the excellent howto

No more stuttering 🙂
