Verify the file hash if you are paranoid. The official .exe for version 6.0.9191 should have an MD5 checksum of 7a4b3f8c1e9d2a5b6c7d8e9f0a1b2c3d (example – always check the site’s provided hash).
In short, is not the newest driver (newer builds like 6.0.96xx exist), but it is widely regarded as a “golden build”—stable, reliable, and well-tested by the community.
