Can't you see the problem? people shouldn't be having to go through those kind of steps and it isn't like it is a one off even when it comes to Windows 10.
An OS fundamentally should enable the end user anything else is secondary MS are taking completely the wrong approach with how they deal with the end user and choices. When I boot up Windows 7 I get what I expected and can get straight onto the task at hand - with Windows 10 there are too many instances when that isn't the case for instance a few days ago (I'd recently done all latest updates and rebooted since) I wasn't feeling great and went to lie down on my sofa and fired up my media system to watch something and take my mind off how I was feeling... about 30 seconds after booting it suddenly popped up with the "Welcome to Windows" screen which I couldn't skip and had to go through a few choices at which point I could get back to the desktop but for the next ~10 minutes various OS components were busy in the background using around 70% CPU so my video was frequently stuttering and occasionally dropping to low bitrate before recovering again, etc. I never have that experience with my systems on Windows 7 ever - unfortunately the hardware for my media setup doesn't have drivers for anything older than 10 and Linux/Android isn't an option with some of its usage.
Can't you see there are solutions already?
You can turn off "Welcome to Windows" screen or skip it if you want, just click Skip for now button. you cant missed it unless you have bad eye sights.
I not had that screen for 3 years now since 1803 and also in Insider builds on VHD as I turned it off in Settings/Notifications & actions.
You will need to untick Suggested ways I can finish setting up my device to get the most out of Windows.
You may also want to turn off Show me the Windows welcome experience after updates and occasionally when I sign in, to highlight what's new and suggested to stop Edge browser pop up with Welcome to Windows after every feature and insider build updates when you log in to desktop. But for me, I prefer to left it ticked so I can use Edge to type in address to browse internet straight away.
Something not right with your media PC system used around 70% CPU usage after 10 mins. Are your media PC on version 1909 or 2004? What CPU and RAM size do it used?
I had noticed the biggest improvement in CPU usage since Windows XP when I installed 1909 on all my devices, all 6 devices CPU usage dropped from 30%, 50% or 70% on both old Meegopad stick and Linux 10 tablet's quad core Atom CPU down to between 0% to 20% when various OS components were busy after 10 mins or opened 1 VMWare VM and many Edge/Chrome/Firefox tabs opened saw around 60% CPU usage on my 8700K before 1909 so after updated to 1909 saw CPU usage dropped to as low as 6% while memory usage at high and between 0% and 1% when desktop at idle with no apps opened. At idle before 1909 had 14% memory usage and after installed 1909 saw memory usage dropped 2% to 12%. Wow very impressive.
When I bought second hand Acer R3 131T laptop manufactured in 2013 from ebay for £75 in 2019 came with crap 2 core Celeron 3050 CPU, 500GB HDD and 4GB RAM, I booted it first time found out it used Windows 8.1, it ran very slow with CPU usage up to 100% all the time. I also found out all drivers was very old dated back in 2013 then I updated it to Windows 10 1909 and installed new drivers from Acer website for other R3 131T model manufactured in 2017 saw CPU usage dropped to 70% and changed some drivers to microsoft drivers saw CPU usage dropped to 30%. I worked on the laptop tweaked for 2 months and added 1TB SSD, 8GB RAM and 25 games that ran fine on 2 core Celeron CPU before gave to my niece for christmas present.
I would done the same thing to fix your media PC.
While probably stuff like that is a little less of an issue if you just use one machine that is in daily use it is a horrid, horrid OS if you run multiple systems some of them which might only be used every other week or so, etc.
I have no idea what the nonsense rubbish you talk about. Windows 10 is not horrid OS when I used 6 devices. Back in November 2019 I had 1 desktop PC, Surface Pro 6 and Acer R3 131T laptop all ran everyday for 2 months until 24 December 2019 just fine with no issues. Also my sister used her Acer laptop for college work, her boyfriend used Lenovo laptop browsed internet and youtube, my niece used Acer R3 131T for school works everyday from 9am to 4pm since lockdown all ran 1909 without issues. Before the lockdown, everybody at my sister workplace at college used over 1,000 PCs all ran Windows 10 1909 on network with no issues. There are now over 1 billion Windows 10 users included Prime Minister Boris Johnson used Windows 10 daily.
