Microsoft will make Windows 8 generally available on October 26th, 2012. We will deliver a service pack prior to that date for PerfectDisk 12.5 client components that will support Windows 8.
We are currently running Windows 8 in our labs here with the latest, unreleased PerfectDisk. Many PerfectDisk users are running PerfectDisk 12.5 today on Windows 8 without any problems, and this is generally expected behavior. However, we are not yet, in the current build, guaranteeing compatibility and therefore our stance today is that Windows 8 is not officially supported. For a point of reference, there are a few behind-the-scene tasks that occur on both Raxco’s and Microsoft’s side that are being done to bring us to full compatibility.
We look forward to delivering PerfectDisk 12.5 Service Pack 5, with full Windows 8 support, in the coming weeks.
