The error reporting feature in Windows XP is turned on by default but you may want to disable error reporting for privacy concerns, if you're not connected to the Internet all the time, or to simply stop being alerted by it.
Error reporting works by prompting you after a critical error in the operating system or in other programs and asking permission to notify Microsoft about it. This way, Microsoft can gather technical information about serious errors from millions of users, helping them develop fixes and service packs.
If you'd like to disable error reporting, follow the easy steps outlined below.
Click on Start and then Control Panel.
Click on the Performance and Maintenance link.
Note: If you're viewing the Classic View of Control Panel, double-click on the System icon and skip to Step 4.
Under the or pick a Control Panel icon section, click on the System link.
In the System Properties window, click on the Advanced tab.
Near the bottom of the window, click on the Error Reporting button.
In the Error Reporting window that appears, choose the Disable error reporting radio button and click the OK button.
Note: I would recommend leaving the But notify me when critical errors occur checkbox checked. You probably still want Windows XP to notify you about the error, just not Microsoft.
Click the OK button on the System Properties window
You can now close the Control Panel or Performance and Maintenance window.
