Can't believe that Microsoft not fix Win 10 network printer issue but break Win 11 too. So, is that actually a feature not a bug?

It seems that session pool is removed in WIP. @aionescu @tiraniddo did you have any idea why?

Did you realize that all #printnightmare fix are try to restrict to administrators? It essentially allow UAC bypass. Of course UAC is not a security boundary, so this is not a security issue.

OK, @gentilkiwi found the 3rd one. I have no doubt that he will find the remains soon, just hope that won't be too soon.

Now we got CVE-2021-36958, is it for the not fixed one? or just another one again?

However, they just pay $5k for #printernightmare , actually it is $0 if I not tweet the demo video. OK, they do not recognize that CVE-2021-1675 is PrinterNightmare, maybe that is why. Well Done! Guess who will report Next Printer Nightmare?
