- My system became almost irresponsive, the laptop fan went full speed (suggesting 100% CPU usage by some process) and the task bar dissapeared. Alt+Tab works but the response is very slow. I had some important unsaved documents.
- If you have the same problem, perform these steps (even if it seems it’s not responding, just wait a bit, it can take as much as 30 seconds for each step): Press Ctrl+Shift+Esc to launch Task Manager, then click on the Processes tab, then click the CPU tab so that it shows the highest CPU processes first (in my case procexp.exe showed 99% CPU usage), click the highest CPU process and press Alt+E (Alt+F if your Windows installation is in Spanish).
- After that process is killed everything goes back to normal. If the task bar is still not there, run “explorer.exe” using Task Manager
