I was asking about the install disk because I was considering a repair install may be the way to go on this.
Can you download the free version of Speccy to see if the product key is the same as the one you got for Win 7 Pro ?
https://www.piriform.com/speccyClick on Operating System in the right pane and that will give you your 25 alphanumeric product key.
To do a repair install, your install disk would need to include SP1 which depending upon when you bought it can determine if it did or not, but you would need the correct key to retain Ultimate.
It may be worth contacting MS to confirm if that product key is for Ultimate, explaining how you upgraded from Pro to Ultimate and what you are wanting to do.
There are two sources that I know of where you can download a Win 7 x64 Ultimate ISO but the first would need to accept your product key to release the download and is from -
https://www.microsoft.com/en-gb/software-download/windows7The second is from -
http://windowsiso.net/Hover over Win 7 ISO and the sub menus to select the one for Ultimate.
I believe these will include SP1.
When you have saved the download, in both cases you will need a program to create the install media.
You can use Windows own USB/DVD Burner tool -
http://wudt.codeplex.com/ or you can use ImgBurn -

A repair install doesn't affect your personal stuff or installed programs but you will need to reinstall all Windows Updates again which may resolve the missing .mum files.
To perform a repair install - go Start - Computer - insert the install media and double click on the drive.
If using a DVD, this will start the process but if using an USB, that will open to the files where you would double click on setup Application.
However, before you go that route, can you run the Step 2 Pre-Scan to see what it reports for the Package .cat and .mum files.
Can you also check Event Viewer by going Start - type eventvwr and press enter.
When Event Viewer opens, ensure Event Viewer (Local) is highlighted in the left pane - if it isn't then just click on it.
When it has read the data, click on Error then on Show All Instances of This Event in the lower right pane.
A while ago I ran the pre-scan on my Win 7 laptop and it produced 2005 Package file problems as I've documented in this thread -
http://www.tweaking.com/forums/index.php/topic,4412.0.htmlMy Event Viewer at the time had a number of ESENT errors listed but also one for CAPI2 Event ID 257.
From a Google on that I ran a cmd prompt as an admin and entered these cmds which resolved those, but they don't always work which was found for others.
net stop cryptsvc
ren C:\Windows\System32\catroot2 catroot2.old
net start cryptsvc
shutdown /r /t 00
A Pre-Scan for me after the reboot came up clean.
One of the repair program's Pro repairs is designed to resolve those missing/corrupt Package files.
If you do decide to upgrade to the Pro version, remember that now it is a one licence/one machine product key, but see how you get on with those cmds.
You can easily reverse them by changing the cmd to catroot2.old catroot2
