What are deskperf.dll.mui Error Messages?


Dynamic Link Library deskperf.dll.mui Errors

Deskperf.dll.mui is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like deskperf.dll.mui, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like sapisvr.exe - to follow. These files were created so that multiple programs (eg. Windows) could share the same deskperf.dll.mui file, saving valuable memory allocation, therefore making your computer run more efficiently.

Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared MUI file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when deskperf.dll.mui is attempted to be loaded either when Windows is starting up, or in some cases already running. Some of the most common deskperf.dll.mui errors include:

Your deskperf.dll.mui file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Windows), or deleted by a malware infection. Furthermore, deskperf.dll.mui file corruption could be caused from a power outage when loading Windows, system crash while loading deskperf.dll.mui, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.



How to Fix deskperf.dll.mui Errors in 3 Steps (Time to complete: ~5-15 minutes)

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your deskperf.dll.mui issue. These troubleshooting steps are listed in the recommended order of execution.


Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.

To begin System Restore (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button
  2. When you see the search box, type "System Restore" and press "ENTER".
  3. In the search results, find and click System Restore.
  4. Please enter the administrator password (if applicable / prompted).
  5. Follow the steps in the System Restore Wizard to choose a relevant restore point.
  6. Restore your computer to that backup image.

If the Step 1 fails to resolve the deskperf.dll.mui error, please proceed to the Step 2 below.

Step 2: Run SFC (System File Checker) to restore the corrupt or missing deskperf.dll.mui file.

System File Checker is a utility included with every Windows version that allows you scan and restore corrupted system files. Use the SFC tool to fix missing or corrupt deskperf.dll.mui files (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button
  2. In the search box, type "cmd" but DO NOT PRESS "ENTER".
  3. Press and hold "CTRL-Shift" on your keyboard while pressing "ENTER".
  4. You'll be prompted with a permission dialog box.
  5. In the box, click "YES".
  6. You should have a black screen with a blinking cursor.
  7. In that black screen, type "sfc /scannow" and hit "ENTER".
  8. SFC will begin scanning for deskperf.dll.mui issues and any other system file problems.
  9. Follow any on-screen commands to complete the process.

Please be aware that this scan might take a while, so please be patient while it is working.

If this Step 2 fails as well, please proceed to the Step 3 below.

sfc /scannow

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many deskperf.dll.mui error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

  1. Hit the Windows Start button
  2. In the search box, type "Update" and press "ENTER".
  3. In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
  4. If updates are available for download, click "Install Updates".
  5. After the update is completed, restart your PC.

If Windows Update failed to resolve the deskperf.dll.mui error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.

Download deskperf.dll.mui Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying deskperf.dll.mui to your appropriate Windows system directory. Microsoft typically does not release Windows MUI files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing deskperf.dll.mui and all other MUI files for Windows. An incorrectly installed MUI file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
