Windows XP Autorun.inf in service pack 3

In your scenario, where you're trying to modify the AutoPlay behavior using autorun.inf, there are a few potential reasons why your setup might not be working. Here are some things to check and adjust: 1. Drive Type: Ensure that the USB drive is recognized as a non-removable drive. The AutoPlay feature does not work the same way for removable drives as it does for non-removable ones. 2. File Attributes: Check that the autorun.inf, backupnow.bat, and backupicon.ico files do not have the hidden or system file attributes set. 3. Path in backupnow.bat: Double-check the path you're using in your backupnow.bat script. Using absolute paths (like 'C:\myfiles' and 'F:') can sometimes cause issues. 4. Icon Location: Ensure that the icon file (backupicon.ico) is in the root of the USB drive and that there are no issues with the icon file itself. 5. Script Output: To test, you might want to add a line in the backupnow.bat that logs errors or outputs. This way, you can check if the script is running correctly or encountering any issues. 6. Windows XP Compatibility: Compatibility issues might sometimes arise with certain modern features or configurations on older operating systems like Windows XP. You can try testing the same setup on a newer Windows version for comparison. By reviewing these aspects and potentially tweaking your configuration based on them, you may find a solution that addresses the AutoPlay behavior issue you're encountering with virtualized Windows XP.
