Frequently Asked Questions

What is a handle in Windows?
A handle is an abstract reference to a system resource such as a file, registry key, process, or thread. Applications receive handles from the OS and use them to interact with these resources.
Can I fix this error myself if it happens in a third-party app?
Usually not, as this is a bug in the application code. Update to the latest version and report the issue to the developer. Reinstalling the app may help if the issue is caused by corrupted files.
