Is your computer suddenly sluggish, with the dreaded 'Windows Modules Installer Worker' (TiWorker.exe) consuming excessive CPU resources? You're not alone! This common issue often arises when Windows is installing updates in the background.
While a certain amount of CPU usage is normal during updates, persistent high usage indicates a problem. Here's how to tackle it:
* **Be Patient (Initially):** Sometimes, the process *is* just taking a while. Give it an hour or two. If it persists, move on.
* **Run the Windows Update Troubleshooter:** Go to Settings > Update & Security > Troubleshoot > Windows Update and run the troubleshooter.
* **Check for Corrupted System Files:** Open Command Prompt as administrator and run `sfc /scannow`. This command will scan and repair corrupted system files.
* **Delay Updates (Temporarily):** In Settings > Update & Security > Windows Update, you can pause updates for a few days. This might give the installer a chance to complete its task or let you install updates at a more convenient time.
If these steps fail, a deeper dive might be needed, potentially involving driver updates or even a clean Windows install. But these simple solutions often do the trick, freeing up your CPU and restoring your computer's performance!
