Mohit Kumar:
Thanks Wai!!
@Mohamad Alhussein I have raised a query with LF will let you know what they say about Enterprise OS
Kalesha Gagguturu:
I also had similar confuse before taking exam after seeing the guidelines of psi requirement, but I took my exam with windows 11 enterprise 22H2 / 21H2 on 22nd Jan and i didn’t faced any issue.
I can suggest to check with psi May give clarity about the same
Mohit Kumar:
@Kalesha Gagguturu your’s is office laptop?
Kalesha Gagguturu:
Yes
It’s office laptop but I had disconnected all vpns before taking the exam. Also it depends on your organization policies on your device
Mohamad Alhussein:
Thank you very much guys, @Mohit Kumar Please keep us updated so that we know what we expect 
Alistair Mackay:
FWIW, I have successfully taken 3 LF exams with the following configuration
Edition Windows 10 Enterprise
Version 21H2
OS build 19044.2486
Experience Windows Feature Experience Pack 120.2212.4190.0
DISCLAIMER: It is not officially supported so I cannot make any guarantee that it will also work for you, however if it is a corporate machine you are using:
• You must have full administrator access to it so that you can stop any program or service that PSI Bridge wants you to.
• You should not use corporate network or VPN in case any required ports are blocked.
Alistair Mackay:
I think the reason they don’t officially support it is because enterprise edition is rarely seen not on corporate devices therefore the above two points catch people out when trying to launch the exam.
Mohit Kumar:
Thanks Alistair
Mohamad Alhussein:
Thank you very much @Alistair Mackay i think then i will give it a try with my Win 10 Ent laptop.
Mohit Kumar:
I checked I can’t disable firewall. so I have to find another laptop
