How to Fix Missing DLL Files on Windows 11 (2026 Guide)

Описание: Restore your system's stability and get your apps running again! In this 2026 updated tutorial, I show you how to fix "Missing DLL File" errors on Windows 11. Whether you're seeing "msvcp140.dll," "vcruntime140.dll," or a generic "DLL Not Found" message, these issues often stem from the January 13, 2026 cumulative update (KB5074109) which caused servicing stack inconsistencies.

I’ll walk you through the standard repair commands and the new Administrator Protection handshake to ensure your system can successfully replace corrupted binaries without being blocked by 2026 security protocols.

In this video, we cover:

The DISM and SFC Combo: Why you must run DISM first in 2026. I show you how to use Terminal (Admin) to restore your system image health before scanning for missing files.

The January Update Standalone Fix: If your DLLs went missing after KB5074109, I show you how to download the standalone .msu package from the Microsoft Update Catalog to bypass the common "0x800f0991" installation error.

Visual C++ Redistributable Reinstall: The #1 fix for gaming errors! I show you how to navigate to the official Microsoft site to download the latest 2026 All-in-One package, ensuring every version of the C++ runtime is correctly registered.

Registering Missing DLLs: I show you the regsvr32 command to manually register a specific file if you've already placed it in your System32 or SysWOW64 folder.

The Administrator Protection Handshake: A look at the new 2026 security layer. I show you how to use the Identity Check (biometric prompt) to authorize system file modifications, a mandatory step for replacing files in protected directories.

Storage Integrity Verification: How to check for the green shield icon in your File Explorer. This confirms that your manual DLL replacement has been verified by the latest Windows 11 security scan.
