1. Check Your Computer for Malware Infection

First and foremost, let’s find out whether your computer is malware-infected. Removing nefarious intruders will help you fix the 0x8000ffff issue and save your system from further damage.

Here are 3 easy ways to identify and handle malware infection:

Utilize Windows Defender

  2. Windows Defender -> Windows Defender Offline -> Scan Offline

Your computer will reboot, and then you will be able to check whether the issue has been resolved.

Run Your Main Antivirus Program
