Hi Henry 59,

1. Is your computer connected to a domain?

Method 1:

You may check if you are using the correct account name. Also check if you have administrator privileges given to the account.

Also check that the folders and files are not read only and they do have write access provided to them.

Method 2:

You may use the steps provided to grant permission to everyone and also take full control. You can also login as an administrator and make the required changes.
Before taking ownership I would suggest you to create a new restore point so that the system may be reverted back in case of any loss of data or irregular behavior.

Follow the steps in the below link to create a restore point - The System Restore tool uses restore points to return system files and settings to an earlier point in time. You can use it to restore the operating system to a point in time in which you did not experience the problem. To restore back you need to have a restore point available so I would suggest you to create a new restore point before taking ownership of the folder. Refer to the below link to create a restore point manually –

You may take the ownership of the folder and then use the steps to grant permission to everyone–

a. Locate the file or folder on which you want to take ownership in windows explorer like C: drive in your case.
b. Right click on file or folder and select “Properties” from Context Menu.
c. Click onSecurity tab.
d. Click on “Advance”.
e. Now click on Owner tab in Advance Security Settings for User windows.
f. Click on  Edit Button and select user from given Change Owner to list if user or group is not in given list then, click on other users or groups. Enter name of user/group and click ok. You can even click on administrator here, if you are logged in as an administrator.
g. Now select User/group and click apply and ok. (Check “Replace owner on sub containers and objects” if you have files and folder within selected folder).
h. Click ok when Windows Security Prompt is displayed.
i. Now Owner name must have changed.
j. Now click Ok to exist from Properties windows.
k. Once you have taken the ownership of file or folder.

Grant Permissions to everyone-

a.Go to C: and then click right click on folder and choose  properties.
b. Then go to  security tab and click  Edit then click Add => Advanced.
c. If you click on advanced now click on  Find Now and choose  everyone and click  Ok.
d. Then again click  Ok and now click on Allow => Full control => Ok.

DISCLAIMER: Affecting system settings incorrectly can cause serious problems that may prevent your computer from booting properly or may result in loss of data. Microsoft cannot guarantee that any problems resulting from the configuration of ownership settings can be solved. Modifications of the settings are at your own risk.

Method 3:

If issue persists you can try creating a new user account with administrator privileges and check if you can perform the restore.

Hope this helps.

Thanks,
