Will the guest account save on Windows?

Question

Malware

If, for example, it happens that due to vulnerabilities, the virus opens from where it should not have been launched (mp4, pictures, etc.). Does the guest account save with all this and will it not allow the virus to start?

Answer 1

No, this is not enough.

Answer 2

In some cases it will help.
But not always.
The standard guest account has quite a few rights.
If you want security, you need to limit them.
The standard guest account has the right to run new programs, and this is the main problem.
The best protection is the Software Restriction Policy.
We simply prohibit the launch of all programs by policies, except for those that are already installed.
Then yes - the mouse will not slip.

Answer 3

Yes, it is enough if you have a password on all accounts with administrator rights. And not just:
- Run as administrator?
- Yes, start

The vulnerability is you and the user who will use the guest. You don't need a "vulnerability" to run a virus. It is enough just to run a file with a virus or malware. Such a virus will operate within the Guest account. All files in the user's directory will be available, as well as shared directories, but no more. All this provided that the virus was launched only with Guest rights.
Again. Passwords for accounts with admin rights and that's it. Run viruses under the Guest and don't worry.
