Update failures and driver-install failures can have different causes, so avoid applying a fix meant for a different code or device.
First, identify what is failing
Before changing settings, record the exact error code and what you were trying to install. A Windows Update error points to an operating-system update problem; a Device Manager error or failed driver package points to a particular device. Also note the device name and the PC or device manufacturer and model. Without those details, it is not possible to identify a specific faulty driver or confirm which package is compatible.

Use the update error code to choose a fix
If the troubleshooter does not help, look up the exact code in Microsoft’s Windows update troubleshooting guide. Update failures can involve incomplete or corrupt update data, a stopped service, insufficient storage, access or permission problems, or an interrupted download. The code is important: a remedy for one cause may not apply to another.

Update or install a device driver
Check Windows Update first
Open Settings > Windows Update and check for updates. Windows 11 delivers recommended drivers through Windows Update; optional driver updates may also be listed when available. Review the optional updates list for the driver you need before looking elsewhere. Microsoft explains the route in Automatically get recommended and updated hardware drivers.

Get a compatible package from the hardware maker
If Windows does not offer the driver, use the official support page for the PC maker or the device/component maker. Match the package to the exact model and Windows version. A similar-sounding device name is not enough to establish compatibility. If Device Manager shows an error, consult Microsoft’s Device Manager error-code instructions as well as the manufacturer’s guidance.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.If Windows Update reports 0xC1900101
Microsoft lists an incompatible driver as one possible cause of error 0xC1900101; it is a clue, not proof that a particular driver is responsible. Its guidance suggests reviewing network and graphics drivers and also lists trying a clean boot. Keep the code and device details available, and follow the PC or component maker’s instructions before uninstalling a driver. See Microsoft’s error-specific update troubleshooting steps.
If Windows system files may be damaged
When code-specific steps point to damaged or missing Windows components, Microsoft documents DISM and System File Checker (SFC) as repair tools. Follow Microsoft’s current command order and syntax in Use the System File Checker tool to repair missing or corrupted system files. DISM normally obtains repair files through Windows Update; if that client is not working, Microsoft describes using a suitable Windows installation or a side-by-side source on removable or network media. Back up personal files before attempting these repairs.
