I have received notice from Microsoft that Classic Shell is blocked because of a few compatibility issues. I am working with them on finding a solution. Stay tuned.
In the meantime you can rename the installer to work around the block.
I have been reading post on here. Saying Microsoft is not listening to the feedback. What feedback are they not listening to? People wanted an iso image for each release, they will have it when the slow ring is released.
Edited to add this and for clarity.
Ivo, Thank you for the info. I didn't see your post, tell I posted this. It took me 25 minutes to post this. I edited my post accordingly
Thunderbird and Firefox have compatibility issues with windows 10 in that they do not print. I do not see M$ trying to block them.
Microsoft should of said it was a temporary block that was their mistake. It must be some new coding in the start menu. I am actually surprised Microsoft is working with IVO.
Some people here said we are supposed to be testing Microsoft start menu. Well you can only test it so far, if Microsoft just wants to test just what comes installed, Microsoft don't need us, Microsoft can do that themselves. I thought we were suppose to test all aspects of the operating system including 3 party software like Seamonkey, Chrome, Firefox, etc.... I don't think Microsoft should even have a button to install new preview button. The reason the button won't be there in the new release. There are two ways people install. Clean install and upgrade install. That what needs to be tested.
Well, I have always used Start8, on 8/8.1/build 9841 (was that the name?), and it is currently installed on 9879, works and installed just fine.
As for Microsoft's new Windows 10 menu, I simply don't like it, so I use Start8. I also use Brink's shortcuts, for Charms Bar and Desktop swapping.
If I didn't have Start8 I doubt I would bother testing at all, you don't need the menu to test other aspects.
Besides, if so many people are using Classic Shell, or other 3rd party start menus, perhaps that should be telling Microsoft something (like maybe people don't like the new interface).
OMG!! ...slap my mouth.
