Basically, almost at random but usually during downloads/installations, the operating system freezes program-by-program, starting with the taskbar. It's not the kind of freezing that turns white and gives the options to 'End Task,' but one where it seems more like an image overlay. Usually you can also tell by the frozen cursor animation, but the cursor can still be moved (for a time. Usually the last thing to go is the active application or the desktop (as in the icon selection box or the context menu).
I have attempted to look through Event Viewer, but other than the forced shutdown I have to perform to fix the issue, there doesn't seem to be anything else of use.
For one run I had Task Manager running on my secondary monitor, but on the freeze there was no unusual spike in any of the sections.
At first I thought it was a graphics driver issue, so I updated both the Intel and NVIDIA graphics drivers. This has not improved the issue.
Any suggestions are greatly appreciated.

Finally, a hotfix for the issue via KB2727113, which should be appearing in Windows Update any time now if it hasn't already.
"On a computer that is running Windows 8 Release Preview or Windows Server 2012 Release Candidate, the system may randomly stop responding (hang) when you work on multimedia or communication activities. This problem may occur during video editing, unified communications, or other multimedia activities.
"This problem may occur because of an issue in the interaction between the state-machine driving dynamic tick transitions and the state-machine-driving clock rate changes." Go to the full post
