How to Fix Media Creation Tool Access Denied Error on Windows 10: Step-by-Step Guide

Encountering an “Access Denied” error while using the Media Creation Tool on Windows 10 can be frustrating. This error usually happens when the tool does not have the necessary permissions to run or save files. Fortunately, there are simple ways to fix this issue and get the tool working smoothly again.

In this guide, we will walk you through easy and detailed steps to solve the Media Creation Tool Access Denied error. Each step is explained clearly so even users with little technical knowledge can follow along.

By the end of this article, you will know how to troubleshoot the problem and successfully use the Media Creation Tool to upgrade or create installation media for Windows 10.

Let’s get started with some quick checks before diving into the solutions.

Quick Note: Prerequisites and Initial Checks

Administrator Rights: Make sure you are logged in to your PC with an administrator account. The Media Creation Tool requires admin privileges to run properly.
Disable Antivirus Temporarily: Sometimes, antivirus software blocks the tool from working correctly. Temporarily disabling it can help.
Check Storage Space: Ensure there is enough free space on your hard drive or USB drive where you want to save the installation files.
Stable Internet Connection: A reliable internet connection is necessary because the tool downloads Windows files online.

Step 1: Run the Media Creation Tool as Administrator

One of the most common reasons for the “Access Denied” error is that the tool is not running with administrator rights. Running it as an administrator allows the tool to have full control to create files and make system changes.

Find the Media Creation Tool file (usually named MediaCreationTool.exe).
Right-click on the file.
Select Run as administrator from the context menu.
If prompted by User Account Control (UAC), click Yes to allow.

After this, try using the tool again. Running as administrator often fixes permission-related issues.

Step 2: Change Folder Permissions Where Files Are Saved

If the tool still shows an access denied message, it might not have permission to write files in the selected folder or drive. Adjusting folder permissions can solve this.

Navigate to the folder or drive where you want to save the Windows installation files.
Right-click the folder or drive, then select Properties.
Go to the Security tab.
Click Edit to change permissions.
Find your user account in the list, click it, and then check the box for Full control.
Click Apply and then OK to save changes.

Try running the Media Creation Tool again after adjusting permissions.

Step 3: Temporarily Disable User Account Control (UAC)

User Account Control can sometimes restrict applications from making system changes, causing access errors. You can temporarily lower UAC settings to see if it helps.

Press Windows + S and type UAC.
Select Change User Account Control settings.
Move the slider down to Never notify.
Click OK and restart your PC.
Run the Media Creation Tool again.
Once done, it’s important to revert UAC back to the previous setting to keep your system secure.

Step 4: Use Command Prompt to Run the Tool

Using the Command Prompt with administrator rights can sometimes bypass restrictions that occur when launching the tool normally.

Press Windows + X and select Command Prompt (Admin) or Windows PowerShell (Admin).
Navigate to the folder where the Media Creation Tool is saved. For example, if it’s in Downloads, type:

cd %UserProfile%Downloads

Run the tool by typing its name:

MediaCreationTool.exe

Press Enter and see if the tool runs without the Access Denied error.

Alternative Method: Use a Different User Account

If the problem persists, try creating a new user account with administrator rights and run the Media Creation Tool from there. Sometimes, user profile corruption can cause permission problems.

Go to Settings > Accounts > Family & other users.
Click Add someone else to this PC.
Follow the prompts to create a new local user account.
Change the account type to Administrator.
Log in with this new account and try running the Media Creation Tool again.

FAQs

Why does the Media Creation Tool say Access Denied?

Can antivirus software cause this issue?

Yes, some antivirus programs may block the Media Creation Tool thinking it is suspicious. Temporarily disabling antivirus protection during the process can help.

Do I need a stable internet connection?

Yes, the Media Creation Tool downloads Windows files from Microsoft’s servers, so a stable and fast internet connection is important to avoid errors.

Lowering UAC temporarily can help troubleshoot permission issues, but it is recommended to restore the original settings after you finish to maintain system security.

What should I do if the tool still won’t run?

If none of the basic fixes work, there may be deeper system issues or corruption. Consider running system file checks or using official Microsoft support resources.
