Hi, Things not adding up. 1. SLIC 2.0 = VISTA 2. Hyper-V SLIC is 2.0 = Vista a) Which version of vista comes with build-in Cert for SLIC-2.0, that is not OEM ? b) Which version of Vista has the VRTUALMICROSFT cert in it ? c) When did Hyper-V first have the SLIC 2.0 BIOS ? d) Can Vista activate on SLIC 2.1, 2.2, 2.3 ? e) Is there a OEM key for VRTUALMICROSFT SLIC ? f) Is there a way to check an ISO file to see which OEM comes build-in ? Thanks. BTW: just in case you have seen it, I am looking for the VRTUALMICROSFT 2.0 SLIC Certificate.
