Hi,
1.
Some files required administrator permission to be copied (which is strange because I am an administrator on my laptop)
I see that problem is because while using CD boot media, you are not logged in that administrator account. That is only why we had to navigate to
C:\Users\xyz.
When booted into the CD, just see that Desktop & compare it with
C:\Users\xyz\desktop & you should be able to understand.
The one way may be : When you are booted into CD, try to login into that particular administrator a/c if possible!
The other way may be to boot into the normal win 7, make a folder directly in the
C:\ & transfer all those files to that folder. Then boot into the CD & simply copy those files from that folder & transfer to the external hard disk.
I always suggested to copy & transfer the files of your personal interest only & not the system files.
2.
Also, the CD took about 5 minutes to boot into
It does not sound very good but can't say. I don't have a working CD/DVD drive. If it works well after boot, its done.
3. Where you saved the snap shot, that matters. Put it to the
C:\
( This question again refers to the point
1. above! )

I also ran into some problems copying files with longer filenames while using the Windows boot CD media. I usually get around this issue by using the "xcopy" command in Command Prompt, since I know Windows restricts the length of filename paths to a certain number of characters. Is using xcopy okay for copying over to my external USB drive when I boot into the Windows CD media?
That's a good input for me. Copy some files without deleting & get your truth.
Everybody has to keep on experimenting.
5. Good job done. You are growing. Temporary files are put by apps/OS to keep raw things ready to be used while doing something. Normally, It is safe to delete temporary files older than 24 hours. Delete all of them.
Your this input makes me feel that you should use cCleaner as well . it should come handy. I would guide you about that. It has to be run from normal win 7 boot.
(a) Download this portable cCleaner :
ccsetup550.zip - Google Drive
(b) Extract it to a folder
(c) Launch
CCleaner64.exe
(d) It opens
Cleaner section. Click
Analyze, analise the results & Click
Run Cleaner when you are sure that you want to remove all that!
At this level I would like you to explore only
Cleaner section. Explore the selected & unselected items on left & make your own selections with this tutorial :
CCleaner.com - Cleaning Your PC
Don't make any changes in the settings, Just explore the 'Cleaner' section & focus only on deciding on left pane what item you would like to tick or untick to scan & remove.
(e) The other section to explore would be
Tools > Disk Analizer. Make different selections to understand what is taking space on your
C:
Never use any registry editors/cleaners & so called pc optimizers whether paid or unpaid!
EDIT : (A) I forgot to mention that eject CD from the CD/DVD drive when not in use. Every time you want to boot into it insert it from within normal windows 7, restart & boot into it.
(B) I am looking for a linux rescue media that will not go into the 'administrator' thing & would just explore internal hard disk as a disk only.
(C) That rescue media will also have a File Manager who would not care for long file names & just copy them.
Keep on experimenting safely! Are you easy ?
Let us know.
Thanks & Regards. ...
