为了修复 sdui.dll error without downloading external DLL files, you must use built-in Windows diagnostic utilities or reinstall the software associated with the file. Downloading standalone DLL files from third-party websites is unsafe and can introduce malware.

```
Wait for the scan to finish (100% complete) and restart your computer.
