Question about installing Windows 10 TP for PC

[white_Shadoww]

I have an ISO file of very early build of Windows 10 TP. I had installed it, dual booted it with 8.1 on my laptop, but because of less hard disk space I uninstalled it. Now, I want to install the TP again, and I have a question. Do I need to download ISO of updated build or can I install the old ISO and if I did so will I get updates through Windows update to the latest build?

You can install the old ISO and then update to the latest one. But as you'll end up downloading the update anyway, I'd go with a "clean" install of the latest ISO.

But it's a whole 4GB of data so I'm hasitating. Data is not cheap where I live. You have any idea how much of GBs the updates would be if I installed old ISO?

I think the update is a pretty good size as well... close in size to the new iso.

Guess, I will just clean install it then. Better option. Thanks!
