I locked myself out of my own (C:) folder through stupidity

[lollygag]

So I was trying to get the files on my my specific account locked from all the others accounts on my home computer and I followed these instructions that I found on the web:

1.) Using an Administrator account, navigate to C:\Users and right-click on the "User A' folder. Select "Properties."
2.) In the "User A Properties" window that appears, click the "Security" tab.
3.) Click the "Edit..." button to change permissions.
4.) In the "Permissions for User B" window that appears, under "Group or User Names," select User B
5.) Under "Permissions for User B" check the box under the "Deny" column for the Full Control" row. Ensure that the "Deny" box is automatically checked for all the other rows and then click OK.

After following these instructions, I discovered to my horror that I hadn't selected an owner for the folder I was protecting, and now that it is locked and the files are secure, I can't even access them and I am unsure of how if I can reverse this process. I cannot access the internet through browsers on that specific account that I intended to view my C: User files with, although my internet connection is fine and I am able to access internet through the others accounts.
forgive my stupidity and any and all help is appreciated

You can try doing a System Restore to before you made these changes.

If a System Restore is not preferable or an option, we can help you undo the bad permissions manually, Lollygag. Run the below commands into a Elevated Command Prompt, then copy and post the second command's output here.

takeown /f "[COLOR=red]C:\Users\UserA[/COLOR]"
icacls "[COLOR=red]C:\Users\UserA[/COLOR]"
