Downloaded Win 8.1 ISO from Microsoft. Does it already have Update 1?

[phositadc]

I bought and downloaded the Windows 8.1 ISO from Microsoft online on Friday night. Going to install it today. Is there any way to tell before installing whether it already has the Update 1 included? If it doesn't already have it, I'd slipstream it in before installing. Thanks.

That update just comes through Windows update, so I doubt it would be included, but I don't know how we could be 100% on that.

I guess you could always just slipstream KB 2919355 and see what happens, but it might not work if it requires a previous update to install properly.

I downloaded the x64 Pro version from the store last Monday and it produced exactly the same ISO file I downloaded last October -- 3,208,960 KB.

I installed and then Windows update provided over 40 Windows-only Critical & Important updates. After a restart, another trip to Windows Update provided the "Spring Update" plus another update. In total, I downloaded around 1.5 GB of updates. Microsoft definitely should update the image it provides. I have read several places that an updated version is supposed to be available at the end of the month.

Go to MSDN, look up the SHA-1 hash value of an ISO with Update 1 (you don't need a subscription to look at that information). Google that hash value, find a download for that ISO, download it, verify hash (using something like HashCheck), and you're done--no fiddling with that stupid setup downloader.

I really don't get the point of Microsoft making these ISO downloads hard to get. All that it's doing is making it harder for legitimate users to reinstall. You'll still need a valid key, and you'll still have to go through product activation, so there are still robust piracy safeguards in place. So I say "screw it"; you apparently already have a legitimate license, so you have the right to to acquire a copy of the ISO.

Assuming the hash values match is it 100% certain that no malware could possibly have been injected into the ISO?

Yes. If the hash values match, you are guaranteed that the bits that you got are bit-for-bit identical to the original images. It is impossible (unless you've got a few million supercomputers and are willing to wait a few billion years) to alter the image without also altering the hash value.

Thanks for the info.
