Interesting, I had a look at that app. and checked it on Virustotal - it came up with PUP detections:

Code:

I'm afraid you have a flawed detector, my friend:)
I downloaded the portable app to Win10-10049 yesterday and it downloaded nicely and worked perfectly without a peep from anything anywhere
A few moments ago I downloaded the standard app to Win8.1 (where it's already installed and works perfectly) and installed it again, without a peep, PUP, or pause and once again it works perfectly.
It has to be installed by administrator and Produkey displays Win8.1, IE and Wordviewer keys.
I have used those utilities for many years and not ashamed to say that I have more faith in Nirsoft and Sysinternals than I do in Virustotal
YMMV

EDIT:
I just installed WSCC on Win10-10049, 64bit version and used a different approach to obtaining the app :)
Using Bing I searched wscc, all lower case, and it delivered a list of colleges, businesses and a link for KLS-Software.
Downloaded WSCC and installed all 264 utilities it offers. No peep, PUP nor pause again and when running Produkey it shows a key for Internet Explorer and Win10TP. Nicely done as usual

Thats's fine - can you also let me have these keys:

HKEY_LOCAL_MACHINE\HARDWARE\ACPI\RSDT

Backup\Microsoft\Internet Explorer\Registration

Is it worth mentioning I have a folder from win 7 when I used Norton 360 called 'N360_BACKUP'? It is an extremely large folder, but I have absolutely no idea what is in it or how to open the files in it.

I haven't use norton for yonks - perhaps others have experience with that, but a clean install would be better IMHO.

I note the old digital river lnks have been removed and only valid retail keys are allowed to download the iso now...even COA keys don't work here Microsoft Software Recovery..

I would just leave as is - the only thing I do is disable hibernate on Windows as it interferes with a Linux dual boot.
