I'm trying to capture a WIM file from an existing windows 7 system. But I encountered a failure. It's said that before to capture a system I need to do something with sysprep. so, what is sysprep in OSD?in ConfigMgr? Does anyone could help me about how to do something with sysprep? to figure out this? oh, forgot that, Actually, I want to do these by boot media. and I just created the TS only contained 'capture system image'. and below is smsts.log -------------------------------------------- Expand a string: WinPE TSManager 10/22/2010 7:33:44 PM 1412 (0x0584) Executing command line: osdcapturesystemimage.exe TSManager 10/22/2010 7:33:44 PM 1412 (0x0584) Succeeded loading resource DLL 'X:\sms\bin\i386\1033\TSRES.DLL' CaptureSystemImage 10/22/2010 7:33:44 PM 1484 (0x05CC) Validating system for capture...
