UUP to ISO - Create Bootable ISO from Windows 10 Build Upgrade Files

Windows 10 ESD Repository

And for the ActioScripts themselves, see Windows 10 ESD Repository

Hmmm.

Should I be concerned that using UUP2ISO on the same set of files repeatedly does not always produce the same results? occasionally I get a different file size, by every single time I build I get a different hash when using the same set of files.

This is simple: Do your ISO images created with UUPtoISO work? If so, I do not see what's the issue?

I've done some tests with file hashes, for instance zipping a folder and checking its hash, then zipping it again and getting a different hash. Nothing special, both ZIP archives can be used and extracted, producing the same content.

If you have any doubts and think that there's something wrong with this, an easy solution is to create ISO images with another method and tool and not use UUPtoISO. I've not seen / made an ISO with UUPtoISO that has not worked. To be totally honest, I've never even checked file hash of a self made ISO file because I feel it completely unnecessary.

No, you don't have to worry about this. Multi threaded compression algorithms sometimes put lookup tables (dictionary) in different order and thus the size and hash can vary a bit.

just another issue - the ESD->ISO conversion tool mentioned in various threads for using with the latest download (1803) of the spring update works fine but the instructions are wrong as the esd doesn't seem to be decrypted (you get a message -- file is not decrypted) but it works fine.

I think the error message comes from trying to decrypt a file that is not encrypted. Check the ESD to see if it's encrypted or not.

Just came across this interesting web page. It allegedly accesses uup online (no need to download gitlab software), and then automatically converts to an iso. No need to paste links etc. I am testing it right now.

Interesting. :)

What is does is download a zip file which you extract, then run the .cmd file as admin. It has basically simplified the iso creation phase by combining the download script with the iso creation script.

Edit- it just failed for me at end of download - trying again.

Edit2 - I just realised I did not run script with admin rights - I think that is why it failed. Will know soon

Edit3 - it carries on fine using admin rights. It is not totally automatic as you hve to enter y to continue, then select what you want eg iso, install.wim etc.


It is not that different but it cuts out the cut and paste of uup download folder (and renaming folder). You do not get any graphical indication, only text indication during download phase.


For lesser experienced users, this is simple to use for sure.

You need to unblock the downloaded ZIP archive, then extract all files in it to your UUP Dump folder (it requires UUP Dump Miniserver being present). Works perfectly, did 8 ISO images early today (PRO & Education, four language versions of each edition).
