a. Uninstall the Beta or RC build of SP1 on the virtual machine
b. Reboot the virtual machine
c. Install the released build on the virtual machine
d. Reboot the virtual machine
e. Shutdown the virtual machine
2. Remove the RemoteFX video adapter from each virtual machine using Hyper-V Manager or System Center Virtual Machine Manager 2008 R2 SP1
3. Upgrade the Hyper-v host from the Beta or RC build to the released build using the following steps:
a. Uninstall the Beta or RC build of SP1 on the Hyper-V host
b. Install the released build of SP1 on the Hyper-V host
c. Reboot the Hyper-V host
4. Re-install the RemoteFX role service on the host(it will be removed in Step 3-a above)
5. Add the RemoteFX video adapter back to each virtual machine using Hyper-V Manager or System Center Virtual Machine Manager 2008 R2 SP1
