You need the administrator privilege to delete this folder.

 
After Windows 7 sp1 is installed today, two partitions cannot be used after the installation is complete. Click the prompt to reject access. Then, after adding the default user permission to the disk, you can open the disk, however, when you delete a file, you are prompted to delete the folder only with administrator permissions. After testing, the folder is finally resolved and shared with the brothers.

After testing, we found that when windows xp was installed, the default permissions for the directories in different disk partitions were removed for the sake of system security. Only the administrator and system permissions were reserved, which made the disk partitions inaccessible, therefore, we only need to add the disk partition permission. Here we can directly correspond to the permission of the C disk permission directory.
1. Add the default user group permissions for the problematic disk (the disk prompts that access is denied)

Ii. Add authenticated users Permissions
Click security tags -----> advanced -----> Change permissions ---> Add authenticated users Permissions, as shown in:

1. Add the user's permission to create folders and add data

2. Continue to add the following permissions for the user

Finally, check the check box to replace all sub-object permissions with the permissions inherited from this object.

After the above settings, you can restore the default permissions of the disk partition, but also solve the problem that you need the Administrator permission to delete the folder!
