Windows 11 is still malfunctioning even after a complete reinstall. I can't install updates, connect reliably, use Microsoft services or Windows Hello, or play games. I've tried several fixes and reinstalling Windows didn't help. My drivers are reportedly installed, the hardware seems fine, and I'm signed in with a Microsoft account. What should I check next?

Start with the PC manufacturer’s support page and manually install the chipset, network, Wi-Fi, graphics, audio, and storage drivers. Windows can appear to have drivers installed while still using incomplete or generic versions. Also check whether Windows is activated, since activation can affect access to some Microsoft downloads and services.
A reinstall does not always rule out hardware or disk problems. Run a memory test, check the drive’s health, and look at Reliability Monitor and Event Viewer for recurring errors. Testing the network adapter, RAM, storage, power supply, and graphics card can help identify a failure that is causing several unrelated features to break at once.
The hardware appears to be working normally so far, but I’ll run dedicated memory and storage diagnostics instead of relying only on Windows’ checks.
The symptoms are too broad to diagnose from the description alone. Check the exact error messages, confirm the system date and time are correct, verify that required services such as Windows Update and Microsoft Account Sign-in Assistant are running, and test with a different network. If possible, provide the PC model, Windows build, activation status, and the specific errors shown by updates and Microsoft services.

I checked, and Windows reports that the drivers are installed correctly, but I’ll compare them with the versions from the manufacturer’s website.
