Issue: How to fix Ctrl key not working in Windows?

Hello. The Ctrl key is not working consistently with my Windows PC. Can you help with this?

Solved Answer

Users may run across a variety of issues when the Ctrl key breaks or malfunctions. The inability to use keyboard shortcuts that rely on the Ctrl key is one of the most frequent problems.
