I have a licensed version of Fences so I though to try out Start10 too.
But it does not really work as I thought it would. I tried uninstalling and re-installing but it makes no difference.
Even though I set Control to show Start10 menu on Start Button and windows key, it only shows Start10 menu if I use Modern style under control. If I use Windows 10 Style I dont see anything different from standard Windows 10 e.g. my Fences dont appear in the All Programs list. (I have enabled the Show Stardock and Fences option)
Now, when I click Start button it shows a few random entries from my Fences in the left hand side of the Start10 menu - but only if I enable Show Recent.
If I unclick 'show recently used' then I get nothing down the left hand side (apart from the Windows 10 Menu link and All Programs link)
So, apart from Recently Used, is there no other way to get some favourites etc added to the left hand side?
