Microsoft this week confirmed that an update to its anti-piracy tool is now available via Windows Update.
The Windows Activation Technologies, or WAT, update adds technology to detect roughly 70 activation exploits that the bad guys have developed to bypass Windows 7's activation protections, according to Microsoft (NASDAQ: MSFT).
"This update for Windows Activation Technologies helps detect validation errors and activation exploits. This update also detects any tampering attempts made to important Windows 7 system files," Microsoft said in a Knowledge Base article describing the update.
The article adds that many hacked copies of Windows 7 are also infected with malware -- malicious code meant to violate the user's computer security, steal information or hold the PC hostage, for instance.
