It will check for genuine windows software product ID
Ransomware - Disables updates until you pay Microsoft for a genuine license.
This application stands for Microsoft Windows Genuine Advatage Tool and checks to see if your Windows is GENUINE, i.e. a LEGAL version. Anyone else who disagrees is obviously thick or wishes to breach Microsofts rules and register an ILLEGAL copy of the Windows Operating System. This application is fully safe !

Best practices for resolving WgaTray issues

A clean and tidy computer is the key requirement for avoiding problems with WgaTray. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the WgaTray.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
