A safer way to troubleshoot Windows 11

Windows 11 problems may be caused by damaged system files, incorrect settings, incompatible drivers, failed software installations, low storage, account issues, malware, recent system changes, or failing hardware. The best repair method depends on the exact symptom, when it started, and whether the problem affects one app, one user account, or the whole computer.

ITFixLab troubleshooting guides are designed to move from low-risk checks to more advanced steps in a sensible order. Before changing the registry, boot settings, partitions, firmware, encryption, or recovery configuration, back up important files and read every warning carefully.
