Windows is one of the most used operating systems, and each upgrade introduces new features and security options. But some errors seem to find their way into every iteration, and Preparing security options is one of them.

Though not strictly an error, it appears as so because of the Preparing Security Options Windows 10 blue screen message. So, let’s find out about the problem and its solutions.

What does preparing security options mean in Windows 10?

When stuck on Preparing Security Options, it usually indicates that the OS is updating security settings. It’s done to keep your computer up-to-date with the latest updates. Here are a few reasons why you are receiving the error:

  • Conflicting antivirus – In most cases, it was a conflicting antivirus that led to the problem. Usually, Malwarebytes installed Chameleon, which triggered the message.
  • Malware – A few users reported that malware or virus caused the Control ALT-DELETE Preparing Security Options message.
  • A pending update – In case there are pending Windows updates, you may come across this message.
  • Slow computer – If the message appears for an extended period when you press Ctrl + Alt + Del followed by the actual options, it could indicate poor performance, and you will have to boost Windows speed.

How can I fix Preparing security options message?

  • When you see Preparing security options, hold the power button for 30 seconds or so, and verify if the message appears after the restart.
  • Unplug any non-critical peripherals from the PC. For instance, the printer, speaker, or headphones, amongst others.
  • Scan your PC for malware. For this, you could use the built-in Windows Security or go with a reliable third-party antivirus that detects all viruses and eliminates them.
