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 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic 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 6resmon command to identify the processes that are causing your problem.

This allows you to repair the operating system without losing data.
