There is no way to roll back, if you have old backup then you can restore it otherwise install fresh one.

Out of interest: what did not work with 8.1?
</div>


<div>
It is a pre-release and not a full release. I wanted the start button and the old fashioned program groups. There is a start button, but it really doesn't do anything more than what the Windows button does. So, it is a teaser and more of an irony than anything else.

Same problem here - it's another Microsoft bungle. A complete waste as far as I can tell. In addition, my antivirus quit working (Kapersky) and now they tell me they don't support 8.1 because it's beta. I cannot get any other antivirus installed either. What a mess!

Hello,<br />
<br />
On a whim, I installed Windows 8.1 preview on top of my Windows 8 installation. Now, I have upgrader's remorse and want to roll back to 8.0 without having to reformat my system. Is this possible, or am I out of luck? <br />
<br />
Thanks,<br />

Rollback from Windows 8.1 Pro Preview

Windows 8 is a personal computer operating system developed by Microsoft as part of the Windows NT family of operating systems, with an emphasis on improving its user experience on tablets. In particular, these changes included a touch-optimized Windows shell based on Microsoft's "Metro" design language, the Start screen, a new platform for developing apps with an emphasis on touchscreen input, integration with online services, support for USB 3.0, Advanced Format hard drives, near field communications, and cloud computing. Additional security features were introduced, such as built-in antivirus software, integration with Microsoft SmartScreen phishing filtering service and support for UEFI Secure Boot on supported devices with UEFI firmware.

Windows 8

The Microsoft Legacy Operating System topic includes legacy versions of Microsoft operating systems prior to Windows 2000: All versions of MS-DOS and other versions developed for specific manufacturers and Windows 3/3.1, Windows 95 and Windows 98, plus any other Windows-related versions, and Windows Mobile.
