While wuauclt.exe manages the update process, the actual heavy lifting is often done by drivers and background services (like the Windows Management Instrumentation or WMI). If a hardware driver on your system is outdated or buggy, it can conflict with the update client’s attempt to patch the system. It’s like trying to replace a part in a car engine while the car is still moving—the two actions conflict, and the engine stalls.

To an overprotective antivirus program, this behavior looks like a malware attack. Sometimes, the antivirus will block wuauclt.exe from writing to the hard drive or modifying the registry. The client, expecting permission, hits a wall and crashes. This is a classic case of the immune system attacking the body. why does wuauclt.exe crash?
