wusa.exe (Standalone Updater in Task Manager) consumes too much memory

Windows Update Standalone Installer (wusa.exe) can be a problematic thing to fix. For starters, you won't see a listing for it in Task Manager's Startup section. It may also not visually consume too much memory by itself but stopping this process appears to have a knock-on effect on overall memory consumption.

wusa.exe is a feature of Windows 10 as well as legacy Windows versions including Windows 7, Vista and Windows Server 2008.

Improve CPU Performance using msconfig

Start->Run->msconfig This nifty utility allows you to disable programs and services that run on Windows startup. One example is realsched.exe, a RealPlayer update-checker that runs out of C:\Program Files\Common Files\Real\Update_OB directory.
