These are the standard permissions for the ProgramData folder:
C:>icacls \ProgramData
\ProgramData NT AUTHORITY\SYSTEM:(OI)(CI)(F)
BUILTIN\Administrators:(OI)(CI)(F)
CREATOR OWNER:(OI)(CI)(IO)(F)
BUILTIN\Users:(OI)(CI)(RX)
BUILTIN\Users:(CI)(WD,AD,WEA,WA)
Successfully processed 1 files; Failed processing 0 files
And this is after installing SketchUp Pro:
C:>icacls \ProgramData
\ProgramData Everyone:(M)
Everyone:(OI)(CI)(IO)(DE,Rc,GW,GE,RD,WD,AD,REA,WEA,X,RA,WA)
NT AUTHORITY\SYSTEM:(OI)(CI)(F)
BUILTIN\Administrators:(OI)(CI)(F)
CREATOR OWNER:(OI)(CI)(IO)(F)
BUILTIN\Users:(OI)(CI)(RX)
BUILTIN\Users:(CI)(WD,AD,WEA,WA)
Successfully processed 1 files; Failed processing 0 files
So it has added Modify access for Everyone (whereas the standard access for nonprivileged users only allows you to add new files and folders) and also an inheritable ACE for Everyone with a custom permissions mask: delete, read control, generic write, generic execute, read data, write data/add file, append data/add subdirectory, read extended attributes, write extended attributes, execute, read attributes, write attributes.
(I believe that set of permissions works out as equivalent to Modify, though it is unusual to assign permissions this way.)
