Nothing too particular…just perform a conventional uninstallation using the Add/Remove Programs control panel applet and selecting PS CS. Note that if you have any other versions of PS on your system, you’ll want to leave the shared files on your system when arriving at the related prompt during the uninstall. That said, if you’re planning to immediately reinstall, I can’t even see it hurting anything if you allowed the uninstaller to remove the shared files. Also, be aware the uninstallation will also prompt you about removal of the activation information. Obviously that should be left in place since a reinstall is planned.
