I have several small msi's that change the registry stopping users
from using certain features of windows such as cmd.exe etc. the
problem is some of these msi's change the existing value from say 1 to
0 but on uninstall they clear the entry and leave it blank. Is there a
way to include in the install a way to backup the original value and
then upon uninstall restore the original value?

Thanks

The quick and dirty way would be to use a couple of custom actions. The
first, executed on install, would save the old value, say, by copying it to
a different name. The second CA would execute on uninstall and read the
saved value from the name created by the first CA, then write it to the
appropriate place.
 
Thanks Jeff..

Probably something involving the Registry, RemoveRegistry, AppSearch, and/or
CCPSearch tables. You'd use the AppSearch or CCPSearch to get the original
registry value into a property; then use the registry table to save that
property in the appropriate place.
