Windows 10: File Permissions

I need help.

A few months ago, since my friends were using my PC, I made a separate guest account for them in my PC and denied them permissions to some of the files in my PC. But, now even though I'm logged in through my administrator account, I'm not able to access or modify those files. It says I need permission from administrator. There is only one administrator account on this PC.

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.

1. Right-click on the folder and select Properties. A pop-up box will appear.
