There currently doesn't seem to be any way in Start10 to make the Windows 10 start menu look like it did before the Anniversary Update (without having the cluttered and annoying All Programs visible on the left hand side). I hope Start10 can implement an option to switch it back. I know many people would love to have that option...
At the moment there are no plans to offer a Win10.0 (Classic) menu.
I hope y'all reconsider. I ended up coming here today because one of the screenshots on the Start10 store page shows the Classic Windows 10 menu, and I was disappointed to find out after downloading the trial that that screenshot was just outdated and it wasn't possible to restore the Classic start menu with Start10.
If the Classic menu or a menu that combines the functionality of the Modern Style menu with access to live tiles were to be made an option in Start10, it'd be an instant purchase for me. Heck, I'd gladly pay significantly more than you're asking for the software now to be able to get back the menu functionality lost in Microsoft's anniversary update.
