Windows Update space

Windows needs more space on my C drive to update and install the next version and I don't have the room.

My Photoshop CC and Lightroom(s) and Bridge take up 7.5Gb on there.

If I was to unisnsatll them, can I put them back on to a different drive again afterwards (D or G drives have room)

Do I just need to download them again and re-intall them? And if so, do I do it through my Adobe Creative Cloud programme? Will I need to re-activate them or not?

Paul.
