Alternatively, run from Settings → System → Storage → Configure Storage Sense or run it now. Enable “Delete previous versions of Windows” and “Delete temporary files.” 4.4 Re-register Windows Modules Installer If TrustedInstaller fails, reset its service:
sxstrace parse -logfile:sxsTrace.etl -outfile:sxsTrace.txt Open sxsTrace.txt . It will show the exact assembly version, architecture (amd64/x86), and public key token required. This is the gold standard for SxS debugging on updated Windows 10 systems. The Deployment Imaging Service and Management (DISM) tool can check and restore SxS corruption:
sxstrace trace -logfile:sxsTrace.etl Then launch the failing application. Stop tracing with: sxsi x64 windows 10 updated
DISM /Online /Cleanup-Image /StartComponentCleanup DISM /Online /Cleanup-Image /StartComponentCleanup /ResetBase The /ResetBase flag removes all superseded components, but note: after this, you cannot uninstall previous Windows updates. On an updated Windows 10, this is safe if you don't plan to roll back.
C:\Windows\WinSxS For 32-bit applications running on x64 (via WoW64), Windows also maintains: Alternatively, run from Settings → System → Storage
To run it:
net stop trustedinstaller net start trustedinstaller Then run: This is the gold standard for SxS debugging
Microsoft introduced to solve this. Instead of a single shared location, each application can request a specific version of a DLL, and the operating system serves the correct version from a central, versioned repository. 1.2 Where is the SxS Folder Located? On an x64 Windows 10 system, the main SxS folder is:
