Exactly 3 identical machines purchased at the same time. Bios moded on all of them perfectly with SLIC 2.1 and WIN 7 installed in 2 and Vista in only one. All OEM activated. Between the 2 machines with WIN 7 one has got ASUS slic and the other Dell. On command prompt slmgr -dlv says clearly that they are OEM channel and activated BUT in one an extra two lines appear (the one with Dell SLIC) one line says Windows Rearm Count:3 and then the other line Trusted Time: xxxxxxxxxxx What could this be? I think I have used the same RTM WIN 7 disc (I have two RTM that I downloaded but cannot recall when used which or if used same for both WIN 7 Machines). The one with Dell SLIC has been going for more than 8 months and today I realized this difference. The machine with Vista is ok. ???????
