Things to keep in mind about the Windows Activation Error Code: 0x44578:

This tech support scam virus is a combination of ransomware and adware, so this is probably one of the worst infections to be dealing with.

Windows Activation Error Code: 0x44578
Your product key should be on the box that the Windows DVD came in or in an email that shows you bought Windows. The product key looks similar to this:
Product Key: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
Activate this edition of Windows

Whatever you try entering in the provided Product Key line won’t activate your Windows, because it is not expired in the first place. This message is only a trick the hackers use to make you call the indicated number and purchase the non-existing Windows activation key or fake tech-support service. The scammers are often very informed in human psychology so be careful not to get talked into purchasing the fake products. Though the lock screen may make it seem impossible, you can, however, remove Windows Activation Error Code: 0x44578 and reset your computer to boot properly again. The lock screen removal instructions are presented below, and the rest can be achieved by scanning your system with a reliable anti-malware tool, like Reimage.

    Ive had this Windows Activation Error Code: 0x44578 appear on my PC once but it soon disappeared. My antivirus have fixed it, I suppose.
