Trojan. Connected to internet
def Trojan! Use Antimalwarebytes for removal
The file, as far as my information goes, is not in any commercial product (e.g. Microsoft Windows, 3rd party product, etc.). Also, the file name masquerades as the operating system. Thus, the file is most likely dangerous.
Cause a blue screen. Had to restart and delete
I'ts an virus, Trojan and KeyLogger...
it kept pitting popups saying i had a virus on my desktop but it definetly did not come from microsoft. delete it if you have it
Trojan ! :(
  email worm  
It is a hard to remove trojan that causes a fake bsod. To get rid of the blue screen one needs a second monitor and quick reflexes to drag the taskmanger window before it can close. After that... close tgw windows.exe process tree and scan with malwarebytes and avira.

Sometimes in extreme cases, repeatedly pops up when not connected to the Internet and does not allow any other programming to occur. In other words, you can't get out of it. The only thing you can do is have a professional come out and attempt to fix it. Or just get a new computer. This virus is 100% annoying

Best practices for resolving windows issues

A clean and tidy computer is the key requirement for avoiding problems with windows. 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. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the windows.exe process on your computer, the following programs have proven to be helpful: ASecurity 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. BMalwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
