Hello,
Thanks for reaching out! I'm Microsoft user like you.
There is no need to set path variable.
I download adb platform tools from my Windows 11 computer and it is working.
In your case please try to download again adb platform tools of any other different version then check it again.
I have attached screenshot for your reference.
In case of additional questions, reach out back to me, and I will be happy to help and try our best to resolve your issue.
Best Regards,
Prakash
