Can't delete things "-blank- is in use by another program"

[zacRupnow]

I'm a new user to Windows (8.1). Trying to delete things (Origin, Steam and AVG, for instillation on another drive - except AVG) and when I do a window comes up telling me why it can't be deleted. "_(file/folder name)_ can't be deleted because it's in use by another program" it doesn't tell me what program or give me an option to stop whatever is using them and I see nothing open in the bar that shows open programs.

i think the proper way to delete programs is go to control panel and uninstall them.

quit out of any programs which might be using those files, then try again

you shouldn't be trying to delete your program folders anyway, just use the uninstaller to avoid left over files and errors

 

have you never used the task manager to see running apps before?

Stop just Stop.

You should never just delete programs from folders.

Move your mouse to the bottom left of your screen, when the windows logo pops up, right click and choose "Programs and Features" at the top. From there find your program and click uninstall, then follow the instructions onscreen usually Uninstall.
