well here's the deal i tried to change the welcome message by modifying winlogon.exe.msi from system32/en-us folder but when i try to replace it it simply ads a space between exe and .msi [winlogon.exe msi] and even if i delete and replace after reboot nothing happens, so can somebody please tell me what i was doing wrong. also have taken ownership of winlogon and my system is a 64 bit version. any help apreciated
