I have administered every Windows platform since Windows 3.1 with the sole exception of Windows 8.1. Because of the "this Windows version is no longer supported" thing over the last several months and updating to "new full versions," I knew Windows 11 was on its way...but I'm not really all that eager to jump on the Windows 11 bandwagon (seriously: I thought they were going to call it Windows 12—my bad!). I've been keeping an eye out for user experiences with the new operating system, and what I've seen so far is leading me to respond as I did to Windows 8.1...which is not encouraging.
With Windows 8.1 it was one damned problem after another, most of them centered around arbitrarily removing user customization capabilities and introducing really weird ways to accomplish the same old tasks, introducing chaos and confusion to what should be seamless transitions for experienced computer users. Then there were crap ideas implemented that were just plain horribly bad ideas that didn't work as planned, and Microsoft's response to those complaints seemed to be, "Let's just wait for the problems to go away. Fixing it is a terribly silly idea—right, guys?" Yeah, Microsoft had released a bona-fide lemon. The only apology they offered was actually a pretty good one: A whole boatload of people got Windows 10 for free. That was how I transitioned from Windows 7 to Windows 10.
Not encouraging: Windows 11 is smelling really lemony to me so far. I'm not going to be too hasty to judge, though; my hope is that Microsoft will not repeat their Windows 8.1 errors, that they will actually address the extant and coming development issues. But, how about we get back to Fatalzo?
I think I know what you mean by "future-proofing," but...you're basically gambling with whatever choices you make in that regard. My computer was custom-built for me while I was recovering from a roadkill incident in BAMC (Brooks Army Medical Center) December 2015, the roadkill in question being me. After going through over two deaths and fifty surgeries, I felt justified in spending $1,600 on a custom-built desktop., specifications then being:
Gigabyte GA-Z170-HD3P motherboard w/Intel chipset
16 GB Skilljaws DDR4 SDRAM
Zapotec nVIDIA GeForce GTX-970 / 4 GB DDR5 SDRAM
i5 6600K 3.5 GHz Quad-Core CPU (water-cooled)
650 W Power Supply
Windows 10 x64 OEM 1507
I had told the guy designing it for me that I wanted it to be able to run Space Marine 4,000, Saints Row the Third, and Watchdogs, and any graphics-intensive games that might come out in the next two years, that I wanted it to last at least six years, hopefully ten. My specs now:
Gigabyte GA-Z170-HD3P motherboard w/Intel chipset
16 GB Skilljaws DDR4 SDRAM
nVIDIA (Gigabyte) GeForce GTX-1660 Super Windforce / 6 GB GDDR6
i5-6600K 3.5 GHz Quad-Core CPU (water-cooled)
Crucial MX500 2 TB SSD
650 W Power Supply
Windows 10 x64 Home (OEM) 21H2
EP-9636GS EDUB LOVE WiFi 6 / Bluetooth 5.1 3K Mbps Networking card
It's just about as upgraded as it's going to get. I could get a slightly better CPU, but it already has the most powerful GPU the motherboard is capable of supporting. Upgrading the CPU would be stupid. I already have the next motherboard to allow even greater expansion of data and graphics processing capabilities, an MSI Z490-A Pro. Next in an i9 or i10 CPU. But, you don't want a gaming computer. Basically, you just want a decent workhorse. With that in mind, considering the current state of Windows 11 development, just stick with a new Windows 10 computer. My best advice is for you to consult a local non-chain computer store and tell them what your needs are, but not one of those crappy hole-in-the-wall places—you want a place with a bigger shop with more technicians on staff. AllGen Computer Warehouse @ allgen.com did mine. Their website is really plain and barebones, definitely not intended to impress with glitz and flash, but AllGen's owner, Dave, put his investment dollars where it does his customers the most good. I've been a customer of theirs since 2005, mostly to buy home OEM components. I know you're not local, but I think it might be worth it to you to pick up your phone and give them a call. If they can't design, build, and ship a desktop to fit your needs and budget, talking to them should give you an better idea of what to look for closer to home.
