    It's also a matter of time and effort. I found what I THOUGHT were proper Win 98SE USB drivers, ("trusted" by Norton, and OK'd by Malwarebytes) but royally trashed the OS, and it ended up faster and easier to just re-install Win 98 than trying to debug it. (But THAT was easy. XP not so much.) but I just didn't want to expend much more time or energy on Win 98.
    Of course,Win 98 worked perfectly with the H-P Laserjet, but that WAS a Parallel Port. (Remember, I got the LJ in 1987...) And there WAS a simple, inexpensive adapter that let a Win 10 (USB only) machine use the Parallel Port LJ. But there are no adapters for a USB printer to be used by a Parallel Port only computer, at least not "used (and/or abused)" and commanding an arm and both legs. Ten to fifteen years ago, they WERE plentiful, but not now.

    None of the so-called second source Win 98SE USB drivers I have tried have worked, and while the Win 98 and even XP machines ARE air-gapped from the I'net directly, any "updates" downloaded with another machine can still contain malware, worms, etc.
    I don't disagree that "old" machines can be, and ARE still usable, but only if they have compatible hardware. And if (actually, when:() the hard drive in my Win 98SE machine dies, I doubt there will be any 32 GB or less "IDE" replacements available ANYWHERE.

    I would think that would only work once or twice before they became VERY suspicious...:(
    Actually, many ink-jet printers ARE (relatively) "dirt cheap." The manufacturers make THEIR profit on replacement cartridges; some brands of printers don't like second source refills. But ink-jets don't come anywhere NEAR the quality of a laser printer for text or other B&W printouts, and the ink is often NOT water [or moisture] proof.

    The following worked for me in VirtualBox. Updates still work as of October's "Patch Tuesday" release(s). Of course, your mileage may vary.

    Windows 11 TPM/SecureBoot/RAM Bypass

    1. You get This PC can't run Windows 11 when the PC is not compatible during setup, e.g. when you install Windows 11 from disc or USB. You cannot proceed at this point as the "next" button is not activate.
    2. Press Shift-F10 to open a command prompt window.
    3. Type regedit and press the Enter-key to load the Windows Registry Editor.
    4. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\Setup in the Registry Editor window.
    5. Right-click on Setup and select New > Key.
    6. Name it LabConfig and press the Enter-key.
    7. Right-click on the new LabConfig key and select New > Dword (32-bit) Value.
    8. Name it BypassTPMCheck.
    9. Set its value to 1.
    10. To disable the Secure Boot Check:
      1. Right-click on LabConfig and select New > Dword (32-bit) Value.
      2. Name it BypassSecureBootCheck.
      3. Set its value to 1.
    11. To bypass the RAM check:
      1. Right-click on LabConfig and select New > Dword (32-bit) Value.
      2. Name it BypassRAMCheck.
      3. Set its value to 1.
    12. Close the Registry Editor window.
    13. Type exit in the command prompt window and press the Enter-key.
    14. Activate the back button in the top left corner of the "This PC can't run Windows 11" window to go back and repeat the system requirements check.
    15. If everything worked out, TPM, secure boot, and RAM should not be a problem anymore during the compatibility check.

    ... I knew someone who did that at Radio Shack. Started in early 90s with a laptop, somehow got zapped... They replaced it with a current model... Over and over...

    What can I say... It WAS R-S:( But then again, even R-S didn't deserve to get ripped off.

    Honestly, though, unless you're into high-end gaming, professional video editing or engineering/cad systems, an i7 (regardless of generation) and 16 GB of RAM is plenty for a Linux PC. It's strange and sad that the Windows OS itself is now the main driver of hardware obsolescence, rather than a person's actual use-case scenarios. All I can say is that I hope to see a lot of excellent used laptops and desktops for sale on eBay in the next couple years. :)
