sxs.dll

The sxs.dll file is associated with Windows Side-by-Side (SxS) component store and is often referenced in system integrity errors. On Windows 7, users have reported Code Integrity audit failures involving sxs.dll, where the system logs that page hashes of the image file are not valid. This can indicate that the file is improperly signed, missing page hashes, or has been corrupted. Such errors may coincide with performance issues like mouse hesitation, system beeps, or application hangs. Troubleshooting typically involves checking system file integrity, running System File Checker (SFC), or reviewing security event logs to identify the root cause of the hash mismatch.
