Windows 10: CMD command to open random file from selected folder

When I open up C:\WINDOWS\System32\cmd.exe or CMD, how do I make it open up a random file from a selected folder? I already know how to make it open up a file from a pathway of folders, if it helps.

Removing Windows.old folder

I recently had to reinstall my OS (don't ask). Once I did there were files that I couldn't delete. Basically SecuROM files. Anyway long story short I found this workaround that I wanted to share with my fellow newbs. This will work for any file and works like a charm. Just follow the directions. *Toast :toast:
Note: there is no space between "Administrators: (F)" I just had to but one in because it kept giving me an "unhappy face"

When installing Windows Vista, Windows stores any existing installation of Windows on the install partition inside a hidden folder called windows.old. This folder could take up a large amount of disk space.

Note: Please check the contents of the windows.old folder before deleting it to make sure there are no files stored there that you may wish to keep.

Deleting the window.old folder using the disk cleanup wizard
Click start
Type: disk cleanup
Press enter
Select "Files from all users on this computer"
Follow the rest of the instructions listed on the wizard and select the option to delete the windows.old folder
Deleting the windows.old folder manually
1) Open an elevated command prompt

Click start
Type: cmd
right-click it under programs
click Run As Administrator
2) Take ownership


Change the directory to the windows.old folder (e.g. cd c:\windows.old)
Type: takeown /F . /A /R /D Y > NUL
3) grant yourself permission

Type: icacls . /grant:r Administrators: (F) /T /L /Q
4) Delete everything

Make sure you close any explorer or command windows that are looking at or inside the windows.old folder (except for the command window you are using). If you don't, you will receive an error while performing this step.

Type: cd ..
Type: rmdir /S /Q windows.old

 

.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.
