Canon camera refuses to open files

[Canonhelppls]

two days ago when I was plugging up my canon into my computer the files for Canon opened and I could look at the pictures I have taken. now today when i try to plug it up, the computer goes to "set up device" instead of opening the file name for the pictures??? how can i fix this? P.S i have a canon20d

Allow the computer to "set up the device" you just plugged into the USB port.  This behavior varies from one brand of PC to the next, and the state of your operating system updates.

[Canonhelppls]

it says that the device is unavailable

Were any changes made to the computer like an OS update?

[Canonhelppls]

yes there was an update

[jrhoffman75]

What OS are you using?

[Canonhelppls]

Windows 10!

The suggestion I have is to check for updates again and see if MS has released additional updates to fix problems.

Could you use a card reader?

[Canonhelppls]

I actually don't have one. I will try that

I never plug the camera directly into my computers, I use a card reader that is permanently attached and just switch the card from the camera to the card reader. It is simpler, faster and doesn't use up the camera battery.
