Important: Before changing drivers, formatting storage, resetting Windows or removing important software, back up important files and make sure you understand what the step changes.

If the Problem Continues

Note what changed immediately before the problem started. Test the affected device or connection with another computer or network when possible. This helps separate a Windows/software issue from a hardware or service issue.
