SEP 12.1 and Windows 8.1 "Blue"
Just wanted to let you know this. As you are no doubt aware, Microsoft just released their preview of the Windows 8.1 "Blue" product.
Currently, SEP 12.1 RU3 and below are not compatible with this release - there are a number of bugs which we are working to iron out.
Please do not install 12.1 on Windows 8.1 Blue for the moment. We are working to support this release with SEP 12.1 RU4, due later this year and will have a beta release available soon, which will work and fix the bugs we are currently seeing.
