Following some Googling, if you're comfortable editing the registry, look for

Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.exe\

For me, OpenwithList in that 'folder' has the entry:
Name: (default)
Type: REG_SZ
Data: (Value not set)

OpenwithProgIDs has an additional entry:
Name: exefile Type: REG_NONE Data: zero-length binary value

If you have other values in either of these, that might point to the problem.
