How are you opening the program you're having difficulty closing? Using a start menu programme or using the metro interface?
Sounds like you could use a little help. I checked into some things that you may be interested in that that I can tell, may help you with the CTRL ALT Delete issue and others. Seems Windows 8 is very different from other OSs. There's no big X to click on to close certain things. First, I'll answer the questions you asked. I put some links below that will help with the other issue:
Is it just default of Dism* to say "The component store corruption was repaired." ?
No. Not default. It is the result of the scan. It checks many more components than that.
a. If not, why did the scan check say "No component store corruption detected." ?
Good question. It's not exactly corrupt, it just was not I think exactly as it should be.
b. If that is default response to receive; What do i do next/Is there anything else to be attempted at this point?
Not that I can see.
c. Is this just "one of those things" I'm unfortunately stuck with until the "true" update is released for this problem?
That is what I have found to date. If you like, you can post with Microsoft here and see what they have to say. I would definately consider it. You may get a better answer than I have found, if the issue continues to bother.
2. I assume that the computer looked alright since you had me work on this problem, currently, Would i be correct?
2a. If not, as i assume you are done lending me your help as there's nothing further you can do if the above is correct,
can i install a few manual updates i found independently?
If you have no further malware-related issues, yes. And yes, continuing to install updates would be okay.
2b. If i remember correctly.. , they are updates for: IDT HD Audio, Ethernet Driver, UEFI update, igfx and Bluetooth.
Your computer looks to be clean, updates should be fine.
Ok, some links here that will help with the cpu issue, opening and closing in Windows 8 so things won't be such a pain: This link, this one, and also this one All have cool tips for opening and closing programs and apps, as well as a few other cool things about 8. Personally I love the keyboard shortcuts
If you want to disable Bluetooth there are instructions here for that.
There's a lot of good running info there that sounds like it should make life easier with Windows 8
And if you'd rather a classic (I.e 7 type) start menu then check this out
Please let me know if the links helped with the settling of things. And please let me know how you get on.
