It injected specific values into the system registry to trick the OS into believing it had already successfully contacted Microsoft's servers and received a permanent confirmation code. Technical and Security Risks
Which option would you like? If you want a different angle, briefly describe it.
Because these tools were created by anonymous third parties and distributed on illicit forums, many versions of "WPA Kill" contained Trojans, backdoors, or keyloggers.
Improperly patching system files can lead to a corrupted OS, causing frequent crashes or preventing the system from booting entirely. Windows Xp Activation Wpa Kill Exe
Using such tools had several consequences:
To circumvent this restriction, underground developers created various activation bypass tools. Wpa_Kill.exe was one of the most prominent "one-click" patchers. How It Functioned

It patched winlogon.exe and licdll.dll to prevent the system from checking the activation status.
To counter this restriction, underground software groups engineered WPA_Kill.exe (often flagged by security firms as HackTool:Win32/Wpakill ). Rather than generating a valid activation code, this tool actively modified core operating system binaries—most notably winlogon.exe and licdll.dll —to permanently sever or bypass the internal validation loop that checked if the OS was genuine. 2.
