Posting here to get more idea about UAC with respect windows 7 variants
I have two machines. a - Uses windows 7 Enterprise 64 bit b - Uses windows 7 Professional 64 bit.
In machine 'a' I can create folders under c:\Program Files\ , In machine 'b' this gives permission error.
cd /d c:\Program Files touch test (permission denied with windows 7 professional)
It is related to windows 7 UAC and virtualization. A search on web points to lot of articles but I could not figure out where the above difference is documented.
