Windows 10: Do i have virus after command prompt opens as "systemssx23xx67"

One time when i was trying to mod my games i clicked on a link i downloaded it and it didn't do anything until like 2 minutes it opened command prompt, it said "User allow" and that point i knew it was bad i clicked cancel and it dint let me leave so i did "CTRL-ALT-DEL" and clicked restart, like 2 weeks later which is right at this moment when i turned on my pc command prompt opened and showed the following; "C:\Users\orlando\AppData\Local\Temp>powershell.exe -ExecutionPolicy Bypass -File "C:\Users\orlando\AppData\Local\Temp\734992760.ps1" Processing junk...

command prompt will not open in safe mode with command prompt

Would I just follow the same steps within safe mode after hooking up to the other system?

 

command prompt will not open in safe mode with command prompt

I am repairing a laptop for a friend and I need to access windows in safe mode and the owner has forgotten the password to the main user. I tried logging on with the administrator profile in safe mode but it is not showing up so I was going to use command prompt in safe mode with command prompt but command prompt will not open when I boot that option. Does anyone have any hints for me to figure this out?

 

.txt will open open in Command Prompt

I miss the Windows XP file association manager, it allowed you to select which of the commands would be executed when you double click a file (open, print, edit, etc...), it was removed since Vista.
Some good people created the Types application, which you can use to select the default action of the file double click, all you go to do is select the "txt" extension from the list, right mouse click, hit "Properties" and on the "Actions" tab right click "open" command and assign "Default" to it.
Hopefully this will solve your problems, although I think your PC is probably infected with some kind of malware that will continuously change that setting back, so I also advise installing some anti-virus like MSE or NOD-32 and preform a full scan.
Good luck.
