Well, if this is a problem for someone, then just stick with Windows 11 without this update then.
But for anyone running stuff older than Haswell, later versions of Windows is far too slow (at least unless you tweak it). Linux might be a better option then.
Expecting a new OS to run on >14 year old CPUs would be like expecting Windows XP to run on a 386…
I got to ask, those running such old systems, what kind of GPUs are you using? Nvidia only offers Windows 11 support back to the Geforce 600 series(Kepler) and AMD the Radeon 400 series (Polaris).
But it is a question that I've been pondering a lot lately; where do people think it's fair to cut support backwards when it comes to (new) software? (both games and desktop software in general).
I personally think requiring minimum Haswell and a "DirectX 12 class" GPU for games is fair today, but I would like to hear other's opinions.
To get some perspective, do recent editions of Mint, Ubuntu and other popular Linux distros install and run on C2D systems? And no, compiling from source is not what I mean.
To add to what was said earlier;
They still do run on anything x86-64 with two cores and ~2-4GB of RAM. (Fedora actually offers a low-RAM option during install.) I think most systems older than Nehalem and Phenom II would be having too little RAM to be doing something useful. Like a typical Athlon 64 X2 at the time had 1-2 GB, good luck running Chrome with that.
But what's more interesting is that several Linux distributions are moving to offer packages compiled with a higher level of ISA support (optional though), as most of them today are complied at x86-64/SSE3 ISA level (with only select packages requiring more).
AMD, Intel, compilers and distributions have introduced
microarchitecture levels of x86-64.
x86-64-
v3 ("Haswell") is the level distributions will start to offer, and as can be seen in various
benchmarks, there is quite a bit of "free" performance to be gained from having the entire system compiled with this. If Microsoft did a similar thing, I would expect comparable results.
But I doubt either Linux or Windows will require x86-64-
v3 anytime soon, as Intel has been "stupid enough" to offer Pentium and Celerons up to Comet Lake without AVX2 support, so x86-64-
v2 will likely be the minimum for a long time.
The reason why MacOS and especially Linux are theoretically more secure is simply from the fact that the user base is infinitely smaller and there is less incentive to write malware for.
This is completely wrong;
1) Mac OS was more plagued with viruses than Windows back in the 90s, despite minuscule market share. Then they switched to a BSD based kernel and the problem went away over night.
2) Security comes from design, not obscurity. Linux and (most) Unix based systems have proper security built into the file system, user privileges, etc.
3) By exposure and potential impact, the most attractive target today is by far Linux, as the vast majority of Internet servers and infrastructure runs on it, as well as all Android phones.
