Why can't install programs?

A friend of mine can no longer install programs on his laptop with Win 10 because the laptop tells him to insert a smart card and enter the password for the administrator. However, the input field is missing and he has never used a smart card. What can he do?

That seems to me to be a virus.

Reinstall once and is good.

Ma

So format the entire laptop, right? Can he then save certain files that he still needs on a USB stick, or is it possible that they also have a virus?

Ky

He can still save the files if possible.

Does the window look like this:

Here is the thread about:

If it does not work, backup and reinstall data.

Was something changed?

Ma

Thank you, we'll try that!

He adjusted something when he wanted to delete his password for accessing his account.

Ky

That's probably what it's all about

There's a trick to booting from the recovery CD, replacing the on-screen keyboard with CMD, then starting Windows normally and gaining access to the machine so that you can now change the password / login process. Search for "hacken windows registration".
