We have a 3rd party application installed on a number of Windows 2008 servers. The problem was discovered that every time we install a service pack (which is basically a full installation), it creates a new entry in Programs and Features AND the directory c:\windows\installer gets bigger which is causing our c:\ to run out of space.
The vendor has suggested that we uninstall all their programs from programs and features and then delete all the files that they are the author for in c:\windows installer (they call them "orphaned" files), and then finally reinstall their product.
I have concerns with this as there are other programs by the same vendor that we do not wish to uninstall.
Can anyone advise?:
Is this the correct way to uninstall? what about the registry?
Can anyone suggest a cleaner way to uninstall?
