Windows 10: How to delete a file on windows and bypass admin password?

One of my files has the admin password, and I am wondering how to delete it without the password. It is a shared computer, and the person who owns the admin account is away on holiday. They don't want to tell me for personal reasons, and I don't want to stress them out. The message is, "Do you want to allow this app to make changes to your device?" And below it asks for the password.

Admin password unknown and missing files after upload


Ok, I know these questions have been asked, but I have tried everything I can understand.
Need to be spoken like a noob - step by step please.
Win10 put on my system everything initially fine, then discovered files missing - tried to install a recover program to be frustrated by a prompt to input an admin password with User [USER-PC\USER]
I have tried every password ever used.
I have tried going to cmd prompt
I cant install anything to circumnavigate because I cant get past this dialogue.

any suggests?
