  • trying to get admin pwd from an XP embedded SP3 install. Admin pword seems to be stored in NT hash only (no LM listed). So I've tried using all the vista tables (free ones) but it returns not found. Any other ideas? Seems to be no forum for support. thx

  • Last livecd 3.6.0 version does not work because it does not have table. livecd version 3.4.0 was very good.

  • Boot my Windows VM from Ophcrack ISO file and it failed to detect my hard drive so it's useless for me. Eventually I removed the password with another program PCUnlocker. Additionally, the rainbow tables are too expensive, I think.
