Modern Chrome and Firefox no longer support these versions. Look into Pale Moon or MyPal for a more secure browsing experience. Final Verdict

Since Microsoft has officially ended support for both operating systems, the standard "Download Windows" pages no longer host these files. Here is how you can legally and safely acquire these ISOs today. 1. Where to Find Official ISO Files

You must manually install the "Convenience Rollup" (KB3125574) and the Service Stack Update (SSU) to get updates moving again.

Because Microsoft retired the "Digital River" links years ago, you have two primary safe bets: Microsoft’s Archive (For Win 7 Retail Keys)

Ensure you are installing Service Pack 2 (SP2) . Without SP2, most modern browsers and drivers will refuse to install. 5. Security Warning

Once you have your ISO, you can’t just drag it onto a thumb drive. You need to "burn" it.
