Today, we’re going to dive into a common and frustrating Windows 10 error that many users—including myself—have encountered:
“Explorer.exe – Class Not Registered”
This error often appears when booting up your computer, and it can prevent you from opening the Start Menu, Search Box, or any built-in Windows 10 apps. In some extreme cases, the screen goes completely black, and Windows Explorer doesn’t load at all—you’re left staring at a blank screen with no taskbar.

Don’t worry though. In this guide, I’ll show you two practical methods to fix this error:
- Method 1 – Fix it if your desktop and taskbar are still visible
- Method 2 – Fix it from a black screen if Explorer doesn’t launch at all
Let’s go through them step by step.
🛠️ Method 1: Restart Windows Explorer and Update Windows
If you’re lucky enough that your taskbar and desktop still appear, this fix is for you. It’s the quickest way to restore normal functionality.

🔹 Step 1: Restart Windows Explorer

After restarting Explorer, let’s make sure your system is up to date.

Once updates are installed, restart your PC again and test to see if the problem is fully resolved.
