What little gaming I do can mostly be done on my DS, Switch or PS4. More game, less fuss. When it comes to gaming hardware, I don't want to be on the bleeding edge, I want to be in the fat part of the bell curve where the development and support resources are.
My 15" HP Spectre was a Windows Experience showcase product, and it was pretty much pure Windows from the start. Was kind of bummed to discover that while the screen has 4K resolution, the Sky Lake i7 CPU wasn't up to the task of smooth 4K video playback, but not bummed enough to consider replacing it just yet - it runs W11 just fine.
My efforts to de-crapify Windows are very basic: I periodically review what's installed, and uninstall items which no longer seem relevant. If the computer seems to be slowing down, or I notice a lot of disk activity, I call up Task Manager to see if there's mystery process consuming resources (typically, it's just Windows Update or Adobe Creative Cloud updates). Before closing Task Manager, I click on the Startup tab and disable items which don't seem to make sense, like Microsoft Edge. Although I use Edge to translate web pages, it runs perfectly fine without being a Startup Item.
I switched off the W11 bottomless scrolling news feed, and W10's search-bar trivia icons and other features which mostly seemed to create distractions. No Registry hacks needed.
That Windows feature which installs random new apps automatically? Off.
By default, the setup process for both Windows and MacOS creates an Administrator-level user account, but I only use it for those items which cannot be sudo'd from a standard-level account.
Misc: Firefox or Chromium (not Chrome) web browsers, Protonmail, Duckduckgo as my search engine. And since I'm not in an environment which relies on Outlook/Excel/Word and other Microsoft products, I use OpenOffice.
Streaming video normally goes via Apple TV, and I do not share logins across different services.
"Smart" TV and UHD disk player: Occasionally connected via Ethernet to check for software updates, otherwise not networked.
Marantz AVR: Option to send reports back to mothership switched off. am able to use it's internet radio feature in a limited capacity without creating a Heos account.
Revo Superconnect: Works OK without creating a Frontier Semi (backend provider) account.
Windows, Apple accounts: Required in order to either set up the computer or utilize features including App Store, iPhone, or Apple TV. I don't do anything special, except to create unique user IDs which I don't use to sign into any other company's services.
Am still using Adobe Lightroom and Photoshop, but periodically review my free and non-free alternatives.
