KernelEx for Win2000 in Windows 2000/2003/NT4 Posted December 12, 2018 9 minutes ago, caiot5 said: Thanks for your answer @blackwingcat What about the regular Service Pack 4? Do I need to install it aswell or may I stick with your guidelines and install just the SRP1v2 ? Nevermind. Found that in order to install SRP1v2 I must have SP4 already installed. I'm trying to follow your step-by-step guide right now. Thank you again.
