I'm really intrigued to know what could have lead the OP to think he wouldn't be able to download again his games on a new computer. o_O

I'll ask another question.

Can I download my games again?

Quote me when answering that.

No, but I can download your games for you.

EDIT: For a small fee, of course.

No, the GOG drm prevents you from downloading your games more than once.
If they're installed for more than 3 weeks they automatically remove the files from your computer.

I have seen stores where you are mailed a direct download link that is disabled a short while later, and DRM-schemes where the software is bound to a machine (and possibly with a very low number of reinstalls) rather than an account were not really unusual a decade ago. OP might have not noticed (or understood) the term "DRM-free" and/or figured that there's got to be some restriction somewhere.

i agree, and i am afraid 50% might not work, maybe even more ...
so, thats why i stick to win7 to play all my old games, cause win 10 is , well i dont know a decent name for it so i guess i wont name it, but i think win 10 is the worst windows, mainly because all the phone home stuff, otherwise i might get it in a few years, retail of course no free stuff.

Or Democracy as its more commonly known.... get the anarchists!

Demo-crazy. Crazy ones should be put into padded cells, not anywhere near demolition equipment.

Windows 10 plays games just fine, I don't know where you get the whole 50% deal. The amount of incompatible games is just as much as with every Windows version ever. But if you're into the phoning home conspiracy theories, I can't change a mind...

Microsoft flat out said that Windows 10 phones home in the EULA, dude. It's not a conspiracy when the people doing it freely admit to it and it's been proven by various tech news outlets and researchers.

As for incompatible games, Windows 10 does seem pretty compatible. The real issue is that it during some upgrades it removes software it doesn't like. I haven't heard a solid theory on how it picks the software to uninstall yet. If I could predict which software was going to go I could work around it, but as it is my whole office is going to stay on Win7 until our PCs die because we rely on very old software that we can't lose.

They make it sound like they want your credit card numbers, your personal details and belongings and all of your extremely personal stuff when everything in the EULA mentions that the data they collect is either 1) related to the software you use, for the purpose of improving the compatibility and decreasing crash totals, or 2) in the case of their services, whatever they need in order to actually use their services as intended.

That and I heard it isn't all different from Vista.

Anyways, it is indeed pretty compatible. However the deal with removing some of that software (Catalyst Control Center was the worst offense) is pretty mysterious.

Partially this is just people realizing how much computer companies have grabbed over the years, yeah. But they are collecting more data than before - the EULA language is so broad that it could remain unchanged while they grab more and more. And there's some troubling specific stuff that made it sound like they definitely are grabbing stuff people consider private.

Also, there's the fact that they baked their services into the OS. If I don't want Dropbox I just don't make an account, but getting OneDrive out of Win10 is a big hassle. There's a big difference between 'optional service you must sign up for' and 'this is part of the OS and you must hunt down how to turn it off'. Even Google isn't as shady about this stuff, and that's saying something.

Then there's the way MS updates keep resetting people's privacy and security settings.

About the updates changing toggles around, that's more unintentional. The entire 1511 update suffered a bit of a holdback from that. Other than that, if you don't want OneDrive, you simply do not sign in to it. Sure it's pre-built, but just like with Google apps, you don't use them if you're not logged in. Hell I'd say MS's implementation of the services allow you to sign in to any individual service at a time using a local account. Only when you're a Microsoft account that you're logged into all.
