Hi everyone. I'm planning to update my PC tablet with Windows 8.1 to Windows 10 by Windows Update. I found $Windows.~BT file and install.esd file and I would like to create ISO file by ESDtoISO app. So, I have 3 questions: 1. If I create ISO file from ESD file downloaded by Windows Update on tablet, could I install Windows 10 on every PC by this ISO or only on this one tablet? 2. When I was creating ISO file from install.esd, there was also created install.esd.orig file. What is it? Is it important? Do I need this file to install Windows? 3. Which ISO file should I create: "Create Full ISO with Standard install.wim" or "Create Full ISO with Compressed install.esd" ? I will install ISO from USB 2.0 pendrive on Pc with 2 GB RAM and 4-core Intel Procesor 1.4 GHz. Which ISO type should I choose? Thank you so much for help and sorry for my English.
