“The resource loader cache doesn’t have loaded MUI entry 0x80073B01” error
on Windows

When I'm trying to create a system restore point, I get the following message: "The resource loader cache doesn't have loaded MUI entry 0x80073B01." Can you help me with fixing this?

The error message "The resource loader cache doesn't have loaded MUI entry 0x80073B01" is a system-level issue that commonly appears during a System Restore operation in Windows. This problem occurs when the Multilingual User Interface (MUI) cache, responsible for handling language-specific resources, fails to load essential components needed for the restoration process.

As a result, the operation cannot proceed, leaving the user unable to revert the system to a previous state. The error often disrupts not just System Restore but also the proper functioning of certain Windows tools and features.  

The 0x80073B01 error is usually linked to issues with corrupted or missing system files, which can prevent the MUI cache from loading properly. Such corruption can be caused by abrupt shutdowns, incomplete installations of critical updates, or malware attacks that tamper with essential system files.

In some cases, third-party software, especially those involving system modifications, may conflict with Windows’ normal operations and lead to this error. Additionally, if the MUI cache itself becomes outdated or damaged, it can fail to retrieve the language resources needed for system processes.  

To fix System Restore error 0x80073B01, it is necessary to verify and repair system files using dedicated tools and ensure that no software conflicts or outdated Windows components are interfering with the MUI cache. 

Proper troubleshooting usually involves eliminating potential sources of file corruption, resolving issues with updates, or restoring the integrity of the affected system components. If these don't work, you can always try repair-installing Windows instead, which can be done using Media Creation Tool.

In the steps continuing in this article,we provide a detailed step-by-step instructions for solving this error quickly and easily. If you rather prefer an automated solution you could check the [d1] PC repair tool identifying and resolving underlying system issues known to cause the 0x80073B01 error, your cure faster and smoother way is below.

Fix 1. Run SFC and DISM

Using SFC and DISM together can repair system file corruption and restore the system image, which often resolves issues with the MUI cache.

• Type cmd in Windows search.
• Right-click on Command Prompt and pick Run as administrator.
• User Account Control window will show up - click Yes when prompted.
• Then, copy and paste the following command, pressing Enter after:
  sfc /scannow
• Wait till the scan is finished. If Windows finds system file integrity violations, it will attempt to fix them. After this, use the set of the following commands, pressing Enter each time:
  DISM /Online /Cleanup-Image /CheckHealth
  DISM /Online /Cleanup-Image /ScanHealth
  DISM /Online /Cleanup-Image /RestoreHealth
  
• (Note: if you get an error executing this last command, add /Source:C:\RepairSource\Windows /LimitAccess to it and try again).
• Close down the Command Prompt and restart your computer.

Fix 2. Update Windows

Installing the latest updates ensures all necessary components are up-to-date and free from bugs.

• Type Updates in Windows search and hit Enter.
• If updates are available, click Install updates.
• Otherwise, click Check for updates.
• If optional updates are available, install them as well.
• When all the update processes are complete, restart your computer.

Fix 3. Disable antivirus temporarily

Antivirus programs can block certain system operations, including accessing the MUI cache during System Restore.

• Open third-party security software and disable real-time protection.
• Retry the System Restore process, then re-enable your antivirus afterward.

Fix 4. Clear the MUI cache

Outdated or corrupt MUI cache files can cause this error, and clearing the cache often resolves the issue.

• Press Win + R on your keyboard and press Enter.
• Type in %localappdata%\Microsoft\Windows, and press Enter.
• Find the MUICache folder and delete its contents.
• Attempt the System Restore process again.

Fix 5. Perform a Clean Boot

A Clean Boot disables non-Microsoft services and startup programs that could interfere with the System Restore process.

• Type msconfig in Windows Search and press Enter.
• Click on the Services tab and check the Hide all Microsoft Services box.
• Click Disable all to disable non-Microsoft services, then click the Startup tab.
• Open the Task Manager, disable all startup items, and close the Task Manager.
• Go to the Boot tab and mark the Safe boot option.
• Click OK on the System Configuration window and restart your computer.
• Restart your computer and attempt the System Restore.

Fix 6. Check for disk errors

Disk errors can cause issues with system operations like restoring files and accessing the MUI cache.

• Open Command Prompt as administrator.
• When User Account Control shows up, click Yes.
• In the new window, type in the following command and press Enter after:
  chkdsk c: /f
  (Note: use chkdsk c: /f /r /x command if you are using SSD as your primary partition)
• If you receive an error, type in Y, close down Command Prompt and restart your device.
• Wait until the scan is finished - you can find the results in the Event Viewer.
