Repair BITS Service

Repair BITS Service fixes the Background Intelligent Transfer Service, which is critical for Windows Update, Microsoft Store downloads, and many enterprise applications. It resets all stuck BITS transfer jobs, re-registers the BITS COM components (qmgr.dll, qmgrprxy.dll), repairs service dependencies, rebuilds the BITS download queue database, and restarts the service with proper configuration. BITS failures are one of the most common causes of Windows Update hanging at 0% download. This repair resolves error codes 0x80070424, 0x8007000E, and stuck download states. Takes about 2 minutes.
