This Build of Windows 7 Is Corrupted is a hoax that falls into the categories of potentially unwanted program (PUP) and Tech-Support-Scam.[1] Typically it's triggered by recently installed adware, though hacked websites infected with cryptocurrency miners[2] might also cause it. The scam intimidates potential victims that the system has recently been infected with ransomware which encrypted the Windows License Key Data File. That's a catch to trick people into calling “certified Windows technicians” on “toll-free” number.

However, Windows License Key Data File corruption is an invented issue here. To scare people into thinking that the problem is real, crooks lock web browser's screen with this tech support scam and do not allow to close it normally. If the potential victim clicks the X button, the following pop-up window may appear:

The server license-key13.xyz is asking for your username and password. The server reports that it is from Windows 10.0.

Your Windows 10.0 License Has Been Corrupted. Enter User Name and Password Or Contact Windows 10.0 Help Desk at Toll-Free 1 (855) 622-0255.

Warning: Your username and password will be sent using basic authentication on a connection that isn't secure.

Do not fall for this trick because criminals will try to swindle your money. According to people's reports, the pretend-to-be Microsoft support member requires paying $200 for Windows License Key Data File recovery and the removal of supposed ransomware. Besides, crooks may also ask for your PC's records and your credentials to connect to your PC remotely.
