Windows 10: Why did windows update without my permission on initial startup?

I just bought a new computer and asked the seller to keep it on windows 10 until windows 11 was more proven.Instead, it updated on its own without letting me stop it during setup. There are several things I dislike about 11 and would have preferred to stay on windows 10 until these were remedied.

No permissions

Hi,

I would suggest you to right click on the user's folder for your profile and check if the permissions shows as "read only'. If this is the case, it might be causing the issue. In this case, I would suggest you to go to C:\User folder, right click on the
folder with your username and follow these steps:

• Open the properties of the main user profile folder where the files are located (such as Documents, Pictures, etc).
  
• Go to the Security tab and click Advanced.
• Check the box at the bottom of this window. It is labeled "Replace all child object permissions with inheritable permissions from this object" and then click Ok.
  

This does a one-time action that replaces the security on all the files/subfolders. It’s one-time, so you won’t find that box checked if you peek at it later. Try these steps and let us know the results for further assistance.
