Obtain file/folder ownership, change the owner to the current user in "Properties → Security → Advanced" and replace the subcontainer; 3. Adjust the permission settings, and give yourself "full control" permissions through "Properties → Security → Edit"; 4. Check whether the file is occupied, close the relevant programs or use Unlocker and LockHunter to unoccupi. Try it one by one to solve the problem.

When you encounter the problem of "You need permissions to do this", it is usually Windows' permission management mechanism that prevents you from operating on certain files or folders. The solution is actually not complicated, but you need to choose the appropriate method according to the specific situation.

Here are some common and practical solutions that are suitable for most ordinary users:

1. Run the program as an administrator

Some operations require administrator permissions to complete. For example, you want to install software, modify system settings, or access protected folders.

Solution:

• Find the program or shortcut you want to run
• Right-click it and select "Run as administrator"
• If the UAC (User Account Control) prompt pops up, confirm

This allows the program to gain higher permissions and bypass some restrictions.

Tips: If you often want to run a program with administrator privileges, you can right-click its shortcut → Properties → Shortcut → Click "Advanced" → Check "Run as Administrator".

2. Obtain ownership of files/folders

When you try to delete, move, or modify a file or folder, if the system prompts that there is no permission, it may be because you are not the owner of the file.

Solution:

• Right-click on the target file or folder → “Properties”
• Switch to the "Safety" tab → Click "Advanced"
• Click Change next to "Owner"
• Enter your username (you can view the current login name in "Start Menu> Settings> Account> Home and Other Users")
• Check "Replace the owner of subcontainer and object" (optional)
• Return and apply changes after confirmation

After completion, you can operate this file like a normal user.

3. Adjust the permission settings of files or programs

Sometimes even if you are a computer administrator, you don’t necessarily have all permissions. At this time, you need to manually give yourself complete control.

Operation steps:

• Right-click on the file/folder → "Properties" → "Safety" tab
• Click the "Edit" button
• Select your user account (if not, click "Add" to enter your username)
• Check "Full Control" below
• Click OK to save the settings

Note: Some system files or registry keys will be locked by default. It is recommended to back up important data before modification to prevent instability of the system due to incorrect operations.

4. Check whether it is occupied by other programs

Sometimes you just want to delete a file, but you prompt for permission issues. This may be that the file is being used by a program.

Coping method:

• Close the recently opened programs, especially the Explorer window
• End suspicious process using task manager
• Or use tools such as Unlocker or LockHunter to force the occupancy

This type of tool can help you quickly find out who is "secretly using this file".

Basically these common ways of dealing with it. You can start by trying it out first with the simplest "Run as an administrator", and then go step by step if you don't. Although it seems a bit more steps, each step is not difficult, just follow the prompts.
