How to Resolve High CPU Usage Issues on Windows 10

The Windows Update Standalone Installer (WUSA) is a tool designed to install Windows updates manually. However, it can occasionally get stuck at “Searching for Updates,” preventing the installation process from proceeding. This guide will walk you through various methods to resolve the issue.

Common Causes of the Problem

3. Outdated Update Components: Older update services or components may be incompatible with new updates.
4. Software Conflicts: Security software or third-party applications might block the installer.
