I hope so, but I don't have great confidence when the demo on that site shows significant delays opening each key and I already see how bog-slow W11 is, even with enough RAM to piss off Sam Altman.

The fastest way through registry if you know what you want, is typing the first few letters of a key name and I expect this will kill off the ability to quickly type through to the key you want.

If I had any, I'd put money on it being slower than the original. While the joke is that it was designed for win95 but typical PCs back then had 4-16MB (not a typo, megabytes) of RAM so shit had to be optimized due to the limitations of the day just to make it all work.
