I hope I don't need to read all 95 pages of that !
You only need to read the linked post
HERE and the next couple which provide screenshots.
It looks like I need to have DISM++
It is linked in that post
HERE.
This picture shows you what links look like.
What is the Windows 7 updater that was mentioned ? I know about 7Up the alternative to WinZip.
7-zip is the file archiver you are referring to.
7UP ( short for 7 updater ) is something I wrote for people that wish to update their
installation media.
It is
not for integrating drivers and updates into an operating system that has already been installed
***********************************************************************************
I've built my brother a new PC with a Gigabyte motherboard with USB3.0 and 3.2 ports.
..he wants to be able to boot to his old Win 7 drive
To make the win7 installation from the old machine work in the new machine:
1. You need the driverframework update (windows6.1-kb2864202-x6.msu ), and the usb3 stack ( XHCI and optional UASP). Those are provided
HERE
If ( and only if ) the new machine has an nvme disk, you will
also want the nvme updates ( Windows6.1-KB2990941-v3-x64.msu and Windows6.1-KB3087873-v2-x64.msu). They are in my signature at the bottom of all my posts.
You can integrate all those into an existing installation using the method described
HERE
2. NOTE: If the new hardware is significantly different from the machine his win7 installation was originally on, probably the registry needs adjusting to work on different hardware. Sometimes win7 can cope with moving to different hardware, but not always - depends how different it is.
It can be done manually, but I am too lazy to explain all that. Several programs are available that can do the registry adjustment.
3. Win7 will recognize it is on different hardware and will nag you to activate it. If it is not activated on the new hardware, it goes into reduced functionality and will eventually shut down.
If he wants to use win7 for a while on the new machine, he will need to use a valid windows 7 license key.
If he has a coa sticker on the old machine, he can try that key.
If it does not activate, type slui 4 in the run box then press ok and a few seconds later window will pop up giving the free MS activation phone number. The operator who answers is probably at the call center in India. If your brother is calling, from the UK they might not ask, but if they do - the correct answer is it is a different motherboard. If asked how many machines the license is being used on, the correct answer is one.
