Windows 10 activation

[Snaw]

Hi guys. I'm building a setup which will cost me around 2k€. So, my budget here is done, and i forgot the OS...

My question is: is it possible to run windows 10 for a month without activate it, and then buy the key? Through creator media tool?
Thanks.

Yes

I've been running Windows without activating it for years, no problems with it

The only thing is you will miss out on a few small features that the paid version has. Most people don't need em. And there will be a "please activate windows" watermark.

But how does Creator Media Tool works?
I downloaded it, but i can't choose the OS i want. I'm in a laptop with Windows 10 Pro, but apparently i cant choose.

If i buy the CD, i can copy the files to a USB right (if the USB is bootable)? My new PC does not have a DVD drive.

I think the only option it gives is the choice of either a 32 bit version, a 64 bit version or both as the download would contain both the home and pro versions of windows 10 and you just have to select the version you intend on purchasing the license key for during the pre installation process.
