I just realized today that I had the CTP for sql 2014 still installed on my laptop today. While trying to uninstall it from control panel (time period had expired by the way) I got the error below:
The Operating System on this computer does not meet the minimum requirement
Naturally being a CTP I didn’t expect any real information out there about the issue but it did bring me to the link below where the often forgotten Setup.exe /Action=Uninstall switch was found. Just posting it on the blog to spread awareness that this is way to Uninstall SQL when in a fix.
