Drag and Drop no longer works for anything

Windows 10 drag and drop no longer works for emails, or files. I tried pressing escape while left clicking. Restarted, restarted windows explorer and even a registry change. Nothing...

This is also all of a sudden happening on a Windows 7 machine at a different office.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Check Antimalware: https://www.malwarebytes.com/
maybe the office is in presence of an attack.

Are you subject to a virus attack? Have you installed incompatible software? This is not a Windows 10 or 7 issue at all. I would look for external issues.
