Thread:Project:Support desk/Update.php Problem/reply

To use update.php, go to the command line of Windows [run > cmd] if XP, or type cmd in search in 7.

On the command line, enter something similar to this, without quotes: "C:\MediaWiki\xampp\php\php.exe C:\MediaWiki\xampp\htdocs\[pathofyourwiki]\maintenance\update.php"

The command line will tell you if the update was a success or not.
