clean 32 bit Win 7 out of my new 64 bit Win 8.1

[Rip per]

Not sure how it happened but my old 32 bit Win 7 merged with my new Win 8.1 and now I have Win 10 all on the one computer!! I would like to clean out the old 32 bit which is from my other computer!
OH! The 8.1 is now a Wins 10!! Becauce the two systems are merged I cant just delete. There are running side by side each other.
So I have two of CMD PROMPTS, DISK CLEANERS.
The 32bit Properties windows!! Because merged!! All Property windows have the same apprearance so you cant tell which is which system.


Sorry I'll explain in more detail!!

I have two laptops! A 32bit Windows Vista 7 and a 64bit 8.1 with the new windows 10.

I have a portable hard drive with the 32bit on it!

One night I had the portable hard drive plugged in to my 64 bit to transfer something!!

After about 20min's while using the 64bit I noticed somethink that looked the 32bit on my screen.

So I investigated!! Which was comfirmed that the 32bit did transfer! Which was not meant to happen!!

So now the 64bit has all the 32bit running through it everwhere!!

Is there any way of getting the 32bit out.

I hope this explanation is more understanding.

Please let me no what you think.
