If you installed Windows Server 2008 R2 SP1 Beta when it was available, you might want to try the RC version that is now available. The new version of the operating system includes a series of features such as dynamic memory for Hyper-V and RemoteFx.
Before you double click on the RC installer file, you might want to know that it is not possible to upgrade the Beta to RC. However, you can uninstall the Beta and install RC once you are done. The process is fairly simple:
- Open Programs and Fearures
- Click View Installed Updates
- Find Microsoft Windows (KB 976932) and uninstall it
Your machine will need to reboot and it can take up to 30 minutes to remove the Beta. Once it comes back, you should be able to install the RC version of 2008 R2 without issues.
