I'm trying to put together an "update all" batch file, so I need a way of checking the following from the command line: 1. Service Pack Level (ie: check if XP SP1 is installed) 2. DirectX Version 3. Windows Media Player Version 4. Specific hotfixes I noticed that most hotfixes updates create a registry entry that can be checked for, but I'm not sure about the SP version, directX version, and WMP version. Any ideas?
