Users can search for a particular error message and retrieve possible solutions. The service is free of charge. Many times, the fix for a Microsoft error requires an operating system update. These programs are easily downloaded through the support center and are available for free to registered Microsoft users.
2. Investigate the warranty protection provided by Microsoft for the software package experiencing errors. If a replacement for your program is necessary to resolve the error, it may be handled for free by Microsoft. Warranties eventually expire and do not cover all potential issues.
3. Confirm if your computer system is still under warranty by the computer manufacturer. While an actual replacement of the computer may not be necessary, manufacturer warranties often include free technical support to troubleshoot any Microsoft problem you encounter. A technician will be able to connect to your PC directly and interact with the system in real-time. Most software problems are addressed easily via this service.
4. Firefox users may install the ErrorHelp extension, which adds a worldwide database of errors to this popular web browser application.
