using DUMPBIN /IMPORTS I made this list of likely dependencies to check

GSWDLL32.dll
comdlg32.dll
SHLWAPI.DLL
MSVCRT.DLL
NTDLL.DLL
WINSPOOL.DRV
GSWAG32.dll
GDI32.dll
ADVAPI32.dll
RPCRT4.DLL
SHELL32.dll
COMCTL32.dll
KERNEL32.dll
USER32.dll
MSVCRT40.dll
MSVCIRT.dll

SHELL and KERNEL cannot be messed with, but if any of the others are missing or older, you might try replacing/adding them after backing up. This would have to be at your own risk, I make no claim that it isn't dangerous.
