Verifying hash or non-corrupt Windows 10 USB drive install after made from ISO?

Question

_{Wednesday, October 7, 2015 10:56 PM}

I have a question. I know that an ISO  can be hash checked to get an MD5, SHA1, etc hash to verify the data is correct and hasn't been altered or corrupted in any way. With the Windows 10 install tool where the ISO is downloaded and then made into a boot USB - is there a way to make sure the Windows 10 install boot USB hasn't been corrupted in any way? Such as a SHA1 hash check for the entire USB drive and verify with a known good entire USB hash? I'm using an English version, with standard Windows 10 Home (x64) - any help is appreciated - thanks!

There are third party tools to check this issue:

In order to use a hash you need something to compare it to.  You would need to get the SHA1 hash for the version of the ISO you are using then compare it to the hash from the MS site to see if they are identical.  You mention win 10 home 64 (I assume English/US) and the hash for that is AFAIK not available.

Thanks for the info. I've used the various checksum utilities to confirm the ISO, but are you aware of any that will check the entire boot USB, and is there any SHA1 checksums to even compare a finished boot USB to? Maybe I'm a little OCD, I don't think there's any exploits or trojans that could corrupt a Windows 10 boot USB that I'm aware of, basically if it boots correctly when you start the install and goes through with no errors its fine?
