I just reinstalled Windows 7 on one of my old PC's but I can't seem to activate it. This is what I did: 1. Reinstalled a fresh copy of Windows. 2. Realized I hadn't done a BIOS mod so I reflashed the BIOS with a BIOS from this site. 3. Registered a certificate and a serial number. I then tested the setup with SLIC_DUMP_TOOLKIT which said everything was OK. I did get a message about which SLIC table to use though. (I selected YES on using the next one) The tool seems to have found everything but W7 still won't activate. I believe it may be one of the reasons below but which one? - I need to install Windows AFTER I reflash the BIOS with a new SLIC table - The current BIOS contains 2 tables and Windows is detecting the wrong one Thanks!
