The System Update Readiness Tool can help fix problems that might prevent Windows updates and service packs from installing. For example, an update might not install if a damaged system file prevents the update from recognizing the version of Windows that’s running on your computer.
If your computer is having problems installing an update or a service pack, download and install the tool, which runs automatically. Then, try installing the update or service pack again.
