I use UltraMon and UMWP Autochanger. Used to use Classic Shell but I don't bother anymore.
Everytime I set a machine up though I have to configure the interface a certain way. PITA.
So we're back to the cmd line prompt from dos? Wonderful.
I started with DOS then Windows 3.x and System 6/7 on the Mac.
I think Windows 8/10 is very poor GUI/UX design.
I dislike the whole index/tag and search for everything. It consumes vast resources for no reason. Unless you are a chronically unorganised person.
I have always been able to get to most things within one or two licks of a mouse. Far less clicks than typing.
But I do use the cmd line a lot in Windows. Its faster because they've buried settings to the far corners of the GUI multi levels deep.
Crikey, who ****** in your cuppa? It's hardly a dos command line, it's an alternative to scrolling through the start menu - hideous as that thing can be (certainly in full screen mode - shudder).
I too started with DOS/3.1/95, albeit at college, so have been using the WIMP/GUI since those days - 8/8.1/10/Server 2012 and Sever 2016 are all geared for the touch screen 'Metro' interface, which is great if you like that stuff (and have a touch screen), but looks gash for those used to the older style; hence why people install Classic Shell. But you can easily customise it on 10 onwards (possibly 8.1 as well) - so it gets back to being reasonably close to the old style.
I've never had issues with the indexing/superfetch/whatever they call it, using vast amounts of resources - even on lowly i3 machines with 4 gigs of RAM - I'd suspect you have another underlaying fault there buddy.
No idea what you had been launching in one or two clicks, but most things in 10 are still pretty much found/launched in the same way - as 10 seems to be a transitional operating system; part is the new 'Settings' menu system, and the other part is the old CPL stuff. Personally I have pretty much always launched things via Run, using the applet names - so I haven't really been bothered by any extra clicks Windows 10 might cause. For me though, I have made it a point to not shun away from the new Settings system, as it is clearly the path that MS are taking - and working in IT, I can't sit there harking on about the good old days.
