My files became inaccessible after installing Windows 8 Release Preview from Consumer Preview

Hi all who might be able to help me here. This is my first here. I have installed windows 8 consumers preview, and then plugged in my backup drive afterwards. All went fine. BUT when I installed windows 8 Review Preview, all my files became inaccessible. Even if I try to change the ownership of the whole disk, then I still need to do it with each folder, which can keep me busy too long. Does any one know how to set this problem right in one small process?

 

 

Here is the error message

 


"You have been denied permission to access this folder"

Hi renierbutler,

Thank you for posting on Microsoft Community!

Based on your post, I understand that your files saved in Windows 8 Consumer Preview, became inaccessible, after installing Windows 8 Release Preview and you received error message, "You have been denied permission to access this folder".

In order to help you further, please provide us the details on,

1.      Have you created a Microsoft account or a local account, to login to windows 8?

 

2.      What files are you referring to? 

 

3.      Are the files protected or hidden?

 

4.      Did you use any software to encrypt the file?

 

You can refer the following Steps on How To Take Ownership And Grant Permissions To Access Files & Folders In Windows 8.

 

1.    Make sure that you have administrative privileges to change the file access permissions, as standard user account holders can’t change the ownership of system files. Just right-click the file whose access permissions are to be changed, and then, select Properties. Now, move to Security tab, and select Administrators (<your user account name>\Administrators) from Permissions box to view the current file access permissions.

2.    By default, users from Administrators group can only read and execute the file, and they don’t have permission to modify and write to file. To gain full file write access, click Advanced, present underneath the permissions box.

 

3.    This will open Advanced Security Settings dialog of file, showing all the permission entries, Owner’s name, etc., with an option to change the file access permissions of selected user. First, off, change the owner by clicking Change. It will open Select User or Group dialog for selecting the new owner of the file. Instead of entering the name of owner, you can use the Advanced option to select the user from list. For this, click Advanced button.

 

4.    In Advanced mode, you can search all the available users by clicking Find Now. It shows users and system objects in the list at the bottom, letting you select user/group to give ownership of the file. If you for instance want to give full file write and access permission to user who belongs to Administrators group, select Administrators and hit OK. Similarly, you can add more users by adding Users group from the list.

 

5.    Once Administrators group is added, click OK to close the Select User or Group window.

 

6.    Upon click, it will change the ownership of the file. Now, you need to add a specific Auditing entry for Administrators group to modify the file permissions (read, execute, write, modify etc). Just head over to Auditing tab, and click Add.

 

7.    It will open Select User or Group dialog, allowing you to add a user object for inserting it into auditing entries list. You can either manually enter the name of user (who belongs to Administrators group) or click Advanced to select the user from the list.

 

8.    Once you add the Administrator to auditing entries, it opens an Auditing Entry dialog to let you specify the file permissions. You can click Show advanced permissions to view and enable all file-related access permissions including traverse folder/execute file, read attributes, read extended attributes, create files/write data, write attributes, delete, read permissions, change permissions, take ownership and more. In order to gain complete control over file, select Success from Type drop-down menu, and enable Full control and hit OK.

 

9.    This will define the file permissions for selected user. Now, click Apply followed by OK to make changes to file access permissions.

 

10. Upon click, Windows Security dialog shows up, confirming the changes made to file security and permission settings. Click OK and then close both Advance Security Settings and file Properties dialog.

 

11. Now, all you need is to open the file Properties dialog, head over Security tab and hit Edit. You will notice that it now allows you to change the file access permissions for all users who belong to Administrators group. Select the user from the list, and under Allow field, check Full control checkbox to gain full file access permissions.

 

12. Now, click Apply, a dialog will pop-up confirming the action. Hit Yes to allow full file access control for selected file.

 

13. Once file permissions have been gained, you will be able to modify file content, rename it, delete and change file’s extension. However, changing default file security settings will leave system files vulnerable to external attacks. So, it’s advised to restore the original file access settings after making required changes.

 

If you need any further help, Please provide us the details and we will help you further.
