It's literally two steps to change from Windows S. That OS was never intended to be a general purpose consumer OS for powerful PC's. It's a purposefully locked down, secure, efficient OS for lower end laptops (aka chromebooks) in large enterprises, schools. Microsoft can't guarantee the security or performance for users who are downloading crapware and files from all over the net.
Not everyone buys a computer to restricted to Microsoft's store and apps and it's web browser and search engine. Then you don't want or like that they want to proceed to collect data information on you in order to turn it off and use. Technically more steps especially if you haven't done it before. Just because it's cheaper system doesn't mean you should be penalized and forced to only use Microsoft Edge web browser and Bing search on it.
Not everyone using more affordable hardware is infested with malware simply because they run great programs that aren't on the Microsoft Store things like Foobar, Firefox, LMMS, MIXXX, BB4WIN, GIMP, Audacity, VLC Media Player, Shortcut, SumatraPDF, VirtualBox, Notepad++, FileZilla, DropBox, Blender 3D, Handbrake, 7-Zip, and many others I missed none of which will run by Windows S Mode standards at least w/o first being converted over to the Window Store into app. I'm sorry, but it's absurd. That's just open source mind you there Steam and your entire Steam library which never mind if the system could play the game or not Microsoft will not allow it in the name security. Apparently security only matters in Windows S Mode though to Microsoft. If you've got a expensive RTX laptop by all means you're just asking to be the victim of malware hence no Windows S Mode laptop on best buy at all. Apparently if you want to run DAW or DJ software on a laptop you should be expected to dish out for a RTX Windows 10 malware laptop.
Step 1) Look up how to switch out of S Mode.
Step 2) Download Microsoft store app to switch out of S Mode.
Step 3) Launch setup Microsoft Account thru email verification process in browser because they force it on the end user and a bit of multi-step process itself with all the hurdles of that.
Step 4) Sign into Microsoft Account.
Step 5) Launch the Store app to turn of S Mode.
Step 6) Turn off Microsoft Account sign in so so it boots straight into Windows without a password prompt because it's a home computer and it's way more convenient. (More a Windows 10 general issue really)
