I tried Classic Shell awhile back. It was flakier than Start Menu X or 10Hmm, it works for me FWIW. I have it on one machine of mine (4.2.5).
It's worked perfectly for me since I had Windows 8.1, (now 10), installed across 3 desktops and a netbook.
This W 8.0 does have its foibles. System Restore does not work. That is why I felt compelled to buy RollBackRX Pro so I could take snapshots instead of doing system images every single time I installed a utility. I suspect the machine is open box. But it does work so...
I would probably just put Windows 7 Pro on if I had a base of operations. But I don't want to experiment too much with the only machine I have. The public PCs in the public and school library you are reduced to a Guest account. You can only save stuff to USB. Don't even think about setting a system setting!!!
So until I have a computer room someplace I have to wing it. Other than having to replace the transformer power plug doodad at least mechanically it has been sound. But stuff that works on most PCs I have to try it and make sure. Like I am sure ToolWiz Time Machine works for many people. But it won't work on this PC. Neither will Shadow Defender. When initializing Shadow Mode it just hangs.
I think the problem is with how this thing boots not with Start Menu 10. It did work for awhile. Which is the strange part.
