A frequently encountered issue with Windows 11/10 is unexplained High Disk usage, which at times freezes all other processes of the system. In many cases, upon checking the Task Manager, it is found that the Windows Modules Installer Worker CPU and Disk Usage is very high—at times even more than 50%!

The Windows Modules Installer Worker, or WMIW, or TiWorker.exe checks for new updates from the Windows server and installs them on your computer system. This process might cause load on the system and, in some cases, push the disk usage to 100%, thus hanging or freezing all other processes. Restarting the system won’t work, and the issue does not resolve itself.
