File Description

applicationcontrolcsp.dll is a dynamic link library (DLL) file utilized by the Microsoft Windows operating system. It acts as a Configuration Service Provider (CSP) module, specifically handling Application Control policies. Windows components and Mobile Device Management (MDM) systems (like Microsoft Intune) use this file to deploy, configure, and enforce application whitelisting and software restriction policies on a device.

Standard File Location

The authentic version of this file is located in the Windows system directory:

C:\Windows\System32\applicationcontrolcsp.dll

Note: If you find a file with this name located outside of System32 or WinSxS folders, it could potentially be malware masking itself as a system file.

How to Fix applicationcontrolcsp.dll Errors Without Downloading

DLL errors are usually caused by file corruption, accidental deletion, or registry issues. You can repair this file safely using built-in Windows diagnostic tools without downloading anything from third-party websites.

1. Run the System File Checker (SFC)

The SFC utility scans all protected system files and replaces corrupted or missing ones with a cached copy stored by the OS.

Press the Windows Key.
Type cmd.
Right-click Command Prompt and select Run as administrator.
Type the following command and press Enter:
```
sfc /scannow
```
Wait for the scan to reach 100% and restart your computer.

2. Run the DISM Tool

If the SFC tool cannot fix the file because the local cached copy itself is corrupted, use the Deployment Image Servicing and Management (DISM) tool to restore the system image.

Open Command Prompt as administrator (as shown in Step 1).
Execute this command to check the health of the image:
```
DISM /Online /Cleanup-Image /CheckHealth
```
Execute this command to repair the image files:
```
DISM /Online /Cleanup-Image /RestoreHealth
```
Once completed, run the sfc /scannow command one more time, then restart your PC.

3. Re-register the DLL File

If the file exists but Windows fails to recognize it, re-registering it in the Windows Registry can resolve the issue.

Open Command Prompt as administrator.
Type the following command and press Enter:
```
regsvr32 /u applicationcontrolcsp.dll
```
(This unregisters the file)
Next, type this command and press Enter:
```
regsvr32 applicationcontrolcsp.dll
```
(This re-registers the file)
Restart your computer.

4. Undo Recent System Changes

If the error started happening recently after an update or software installation, you can roll back your system state.

Type System Restore in the Windows search bar and select Create a restore point.
Click the System Restore... button.
Choose a restore point dated before the error started appearing.
Follow the on-screen prompts to complete the restoration.
