Before you download
- Windows repairs its own files: run sfc /scannow, then DISM /Online /Cleanup-Image /RestoreHealth in an administrator window, and install the latest update. That is the fix the winmm.dll page recommends.
- Use this copy when a program needs the file in its own folder, or to compare it with yours. It must match your Windows release and build: x64 is for 64-bit programs on 64-bit Windows. A 32-bit program needs the x86 set, even on a 64-bit PC.
- Do not copy it into System32 or SysWOW64: Windows protects those folders and the next update replaces the file anyway.
