The only thing left right now would be for someone to reverse the keygen binary and recreate the source, possibly for a web version. Also something interesting, it seems like there can be more than one Confirmation ID corresponding to a single Installation ID. Watch any video where someone activates by phone, input the IID they get into the keygen, and you will see that the result differs from the CID they get in the video through the official Microsoft website/call. Nonetheless, they both work.
I still have the original source, actually. I doubt that any web version would last long while MS is alive.
Can you send us the source? The good thing about the Internet is that when you post it, it's 99.9% likely people have backups and 80% likely people will share it.
Strange, I tested it on Server2003R2 Standard retail (x86), it worked pefectly (it worked perfectly also on old installs with antiwga installed and still it worked perfectly) Then I tested it on Server2003R2 Standard retail (AMD64) and it didn't work ("failed to initialize the licensing service" message)... Edit: It works, but unlike in x86 you have to insert the numbers manually in the activation GUI
I had zero problems on x86, tested on half dozen of installs, fresh and old, client and server. Clearly the mileage varies...
I don't know about others but I got this keygen more than 2 years ago directly from @diamondggg. He literally wrote to have it and was kind enough to share it. The reddit post with the GDrive link is just 9 months old. The keygen has Russian strings in it so it made me wonder if it came from a russian board.
VL mode is fine only for WinXP Pro (need conversion tools from non-vl to vl though for pro) - won't work with other editions like XP Home for other WinXP editions like Home & MCE (media center edition), OEM SLP activation works best with those other editions
Well, since the source was shared anyway, here is one method to get the mandatory private key we see on the line 729 of the xp_activate32.c file (0x40da7c36d44c04e21b9d10f127c1). The big parts were already done by researchers and documented in a paper. The only things I did when I worked on that project 2 years ago (thanks to @diamondggg 's Sagemath code) were using the CRT and inverse mod functions from the NTL. Also, to automate things, I quickly made installation and solver scripts. The private key was computed in less than 5h on my 7th gen i7 laptop. Tested on Ubuntu 22.04. anonfiles(.)com/E8749bu0zb/XPActivationPrivateKeySolver_tar_gz
