How to use 4 Cores in Windows 2000

[erpdude8]

OP needs to install (or upgrade to) a higher edition of Win2000 such as Windows 2000 advanced server, which does support 4 cores (though up to 8 CPUs or 8 cores) unlike the Pro edition

blackwingcat is using Win2000 advanced server edition on one of his computers as I noticed on his web site

Only server editions of Win2k will handle at least a quad-core CPU; Win2k Pro is only good enough for 2 CPUs or 2-core CPUs

https://en.wikipedia.org/wiki/Windows_2000

server = 4 CPUs w/ up to 4Gb of RAM

advanced server = 8 CPUs w/ up to 8Gb of RAM

datacenter server = 32 CPUs w/ up to 32Gb of RAM

I found the solution to create a .reg file with this code and execute it:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager]
"RegisteredProcessors"=dword:00040960

Then your Windows 2000 will support up to 65,536 cores. It works on Windows 2000 Pro, Server, Advanced Server, Datacenter Server. Also Windows XP and 2003.

[o] Complete, let's move on!
[x] Impossible or I do not know if you can
[?] Possible but I can not find the solution

[o] Use many cores
[?] Use PAE 32GB in W2K Pro
[x] Install Windows 2000 in Kaby Lake and later
[?] USB 3 support in Windows 2000
[x] Running games and only 64-bit programs in Windows 2000

Just tried that on the windows 2000 installation I have (with Blackwingcat's extended kernel) and it works!  I can see 4 cores of my amd processor in windows 2000!

I'm not sure of its legitimacy, but I have read that there's a *super* rare version of Windows 2000 Datacenter Server which is 64-bit (I think it was called "Limited Edition" or something similar, and only ran on Itanium CPUs). Perhaps if someone can find a copy of that, it can shed some light on how it compares to 32-bit 2k, allowing for ways to mod the 32-bit 2k kernel/user land to incorporate some 64-bitness?

Another way might be to examine Windows 2k3, but that one's different enough that I don't expect it to be very relevant (else someone would've thought of it by now).

That being said, modding 2k to run most XP-era stuff (and maybe some Vista/7-specific stuff too) is still more than enough to ensure that it'll remain relevant for at least several more years, as most Windows software still supports 32-bit CPUs, to an extent. That, in my mind, renders 64-bitness somewhat pointless in most cases (the only case where it would be genuinely useful is to allow more addressable RAM, but we have PAE for that).

I have high temp problem with my Dell Latitude D630 with Windows 2000.

I have fully updated Windows 2000 SP4 with Blackwingcat's Extended Kernel. Registry fix not working. My Core 2 Duo T7100 still having 55-65C even while Idle with CPU 0-2% usage. Normal temp is 38-40C.

Windows 2000 does not support dynamic frequency scaling, so my guess would be that your CPU is simply running at 100% all the time, hence the high temperatures. You will need 3rd party software to control the frequencies.

Can you recommend a program to control the CPU frequency?

K10stat but it is only for older AMD CPUs. You may need something different depending on your CPU family.

Interesting but it doesnt work for me with newest BWC kernel, using W2k Professional 2011 iso, it only detects 2 cores instead of 4 on my Xeon E5430

Edit:

 Ok, I just installed Extended Core over Extended kernel and 4 cores are working good. sorry!

Hello,
is there a German version of the Extended Core? If not, is there a way to install the (English) version of Extended Core on a German Windows 2000?
