SOLVED Windows 10 Update Failure

[davidhk129]

Windows 7 does not have a built in feature or function to mount ISOs natively.
Microsoft has provided a option http://www.microsoft.com/en-us/download/details.aspx?id=38780

Yes. I forgot Mount ISO feature starts in Windows 8.
My apology to the OP.

In that case, download the Windows 10 ISO to USB or DVD > set the Bios to boot from the media > insert the media > restart computer > installation will be gin.
