سلام،
جواب سوال شما در زیر آمده است.
That's correct: "Iranian Standard Persian Keyboard (ISIRI 9147) (Version 2.0)" is the successor of "Persian Experimental Standard" packages and you should have no problem uninstalling the old ones.
The technical enhancements in Iranian Standard Persian Keyboard (ISIRI 9147) version 2.0 are:
- Mapping Zero-Width Non-Joiner (ZWNJ) on Shift+Space.
- Support for all recent Windows (desktop/server) versions (XP, Windows Server 2003, Vista, Windows 7, Windows Server 2008).
- Supports all platforms (i386, amd64, ia64, wow64).
- Fixed the conflict with Microsoft Persian layout (usually happened in Vista, 7, Server 2008).
- Layout will be activated automatically after installation.
