Welcome, alex123fire and gbmacman, to MSFN! Actually, homiebrah, WMC.EXE should be put in SVC-POS, which also uses those same switches. THis will ensure that XPCREATE does not try to slipstream WMC. As for all your errors, gbmacman, I do believe, as Body suggests, shlwapi.dll is the cause. I cannot remember which hotfix this file is in, but there does seem to be a version conflict.
