How to Fix Loose Keyboard Keys
The Windows key, located at the bottom left of your keyboard, is your gateway to the Windows operating system. It opens your Start menu, giving you easy access to your important apps and files, but you can also use it as part of other keyboard shortcuts to save time and improve productivity.
When your Windows keyboard key breaks, you’ve lost one of your most basic tools. Unless you’re willing to unlearn some of the most basic Windows skills, you’re going to need to fix your broken keyboard key instead. There are a few ways to do this, so to help you out, here are a few steps you can follow.
