  • Click on Activation on the left-hand menu.
  • Look for the Switch to Windows 10/11 Home or Switch to Windows 10/11 Pro section.

Don’t pay ransomware authors – use alternative data recovery options

Malware attacks, particularly ransomware, are by far the biggest danger to your pictures, videos, work, or school files. Since cybercriminals use a robust encryption algorithm to lock data, it can no longer be used until a ransom in bitcoin is paid. Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data. Otherwise, you could also lose your money, along with the files. One of the best tools that could restore at least some of the encrypted files –  Data Recovery Pro.
