Whether you’re a casual user or an IT professional, these steps will help you regain control and get back on track.
What is Windows ERROR_75: Access Denied?
Before we dive into solutions, let’s understand the error. ERROR_75: Access Denied usually indicates that your Windows system has been denied access to a specific file, directory, or system resource. This can result from permission issues, corrupted files, security software interference, or system misconfigurations.
Common Causes of ERROR_75
- Insufficient file or folder permissions
- File or folder in use by another program
- Corrupted file system or disk errors
- Interference from antivirus or security software
- Network resource restrictions (if accessing shared drives)
- User account restrictions (e.g., lack of administrative privileges)
Step-by-Step Guide to Fix ERROR_75: Access Denied
Step 1: Identify the Problematic File or Folder
First, figure out which file or folder is causing the error. The error message or event logs usually mention the path. Knowing this will help you target your troubleshooting.
Step 2: Run as Administrator
Often, the error results from limited user privileges.
- Right-click the application or script throwing the error.
- Select Run as administrator.
- Try running the task again.
If this fixes the problem, it means elevated permissions are required.
Step 3: Check and Modify File/Folder Permissions
Incorrect permissions are the most common cause.
How to check and modify permissions:
- Right-click the file/folder and select Properties.
- Go to the Security tab.
- Click Edit to change permissions.
- Select your user account or group.
- Check Full control or the necessary permissions.
- Click Apply and OK.
Tip: If your user account isn’t listed, click Add, enter your username, and assign proper permissions.
Step 4: Take Ownership of the File/Folder
Sometimes permissions look fine but your account isn’t the owner, which blocks access.
To take ownership:
- Right-click the file/folder → Properties → Security tab.
- Click Advanced.
- At the top, click Change (next to Owner).
- Type your username, click Check Names, then OK.
- Check Replace owner on subcontainers and objects.
- Click Apply and OK.
Try to access the file again after this.
Step 5: Close Programs Using the File/Folder
If the file/folder is in use by other programs, Windows may deny access.
- Press Ctrl + Shift + Esc to open Task Manager.
- Look for programs or background processes that might be using the resource.
- Select the process and click End Task.
- Retry your action.
You can also restart your computer to ensure no handles are locked.
Step 6: Disable Antivirus or Security Software Temporarily
Sometimes, antivirus software restricts access as a security precaution.
- Temporarily disable your antivirus or security software.
- Try performing the task again.
- If it works, configure exceptions in your antivirus settings.
Warning: Re-enable antivirus immediately if the test doesn’t solve the error!
Step 7: Check Disk and File System Health
Corruption can trigger access errors.
- Open Command Prompt as Administrator.
-
Run the command:
chkdsk C: /f /r /x
Replace
C:with your drive letter if different. - Allow the scan to complete and fix errors.
- Reboot and test again.
Step 8: Adjust Network Share Permissions (if accessing network resources)
If ERROR_75 happens while accessing a network drive:
- Verify you have read/write permissions on the network resource.
- Ensure your credentials are correct.
- Ask your system/network administrator to verify shared folder rights.
Step 9: Use System File Checker to Repair System Files
If Windows system files are corrupted:
- Open Command Prompt as Administrator.
-
Run:
sfc /scannow
- Allow the tool to scan and repair files.
- Restart the computer afterward.
Step 10: Create a New User Account (If All Else Fails)
As a last resort, your user profile might be corrupted.
- Open Settings → Accounts → Family & other users.
- Click Add someone else to this PC.
- Create a new local or Microsoft account.
- Log out and log in with the new account.
- Test if the error persists.
