Noticed today that during the Build conference that Microsoft released an update to Windows 8.1 and also for Windows Server 2012 R2.

The improvements have been blogged at this MS link

I downloaded from my MSDN and started installing

In the Update zip there is a text file describing which KB that should be applied first and in what order.

No problems during the installation but several reboots though 😛

And once installed I can among other things see that when logging in I get to the desktop directly and I also can find the power button and search from the startscreen!

Good luck in your upgrade 🙂
