Solution 1: Run SFC and DISM Scans

Windows includes built-in tools that automatically scan your system and replace missing or corrupted system files with healthy, cached versions.

Execute the Deployment Image Servicing and Management (DISM) tool first to fix the local Windows recovery image:

Solution 3: Re-register the DLL Module

```
regsvr32 /u wpndatatransformer.dll
