Take a look in Downloads. C:\Users\????

1. You will not find any Windows 7 ISO per se in your Windows installation.

You may download Windows 7 Ultimate SP1 32bit ISO from the Digital River server.
Windows 7 Ultimate SP1-U ISO
Official ISO Downloads

The downloaded ISO can be found in the usual download location mentioned by theog in the previous post.

2. You can make your bootable Windows 7 installation pen drive with MS Windows 7 USB DVD Download tool. Microsoft Store Online

You can also use Universal USB Installer Universal USB Installer – Easy as 1 2 3 | USB Pen Drive Linux to create the bootable pendrive.

If you have not noted down the Product Key or cannot locate the COA sticker on which you can find it, install and run Speccy on your existing installation and note the Product Key before starting your clean install. Check and double check that you have not made any mistake. Speccy - System Information - Free Download

Where did you get Win7 Ultimate? Was it downloaded or did it come preinstalled with the machine?

Reinstalling Windows 7

To answer your question.

No, you can not. Windows product keys are exclusively associated with a particular version of Windows.

You may download Windows 7 Ultimate SP1 32bit ISO from the Digital River server.
Windows 7 Ultimate SP1-U ISO
English x86: X17-59463.iso

Jumanji please remove the download link as it has corrupt iso image My 2.4 gb downloaded wasted.

Absolutely correct ultimate key is not working with professional version although ultimate is dearer then pro.

There should be nothing wrong with that ISO file. Try this one which is the same:
