You can remove all tiles, though the right side remains there, though empty. I'd suggest keeping a tile or two just for quick view (Neather? RSS? News?).
"I'm on a metered connection" setting is available. It won't download updates.

I have a retail Windows 7 Ultimate... And the automatic updates "feature" kind of makes me question whether I want to upgrade or not.

For those worried/annoyed by the forced updates thing, MS provided a tool in the beta stage to get around that, and ZDnet have and article on that and where to get that tool:

http://www.zdnet.com/article/microsoft-releases-tool-to-hide-or-block-unwanted-windows-10-updates/

I'm in no hurry to try it out. Win7 is doing everything I need at this time, and waiting will let all of you other beta testers find the problems before I get around to upgrading ; )

Are there any GOG games yet that weren't compatible with Win 8.1 but will be compatible with Win 10?

I figure that I will wait until Service Pack 1 before deciding if Windows 10 is worth trying. Give the bugbears some time to settle down.

There will not be service packs, this is a rolling relase, but a big patch is supposed to come in October, I think it's better to wait until then to see if most bugs and annoyances get fixed.

Aren't service packs just another name for big patches?

I saw this in the agreement and it seemed unusually pleasant.

Patience is a virtue.

I've opted to do it. One of the advantages here is that I can unambiguously use this copy on my VM without having to worry about MS changing their mind at a future time.

The licensing terms on this copy appear to be a bit more generous than usual, which is probably a sign of something sinister. Still, I doubt very much that I'll be using it very much. There's a handful of things that I'll need Windows for, and most of the time I'll be using Linux anyways.

Still it's nice to have a copy of Windows for those few things I can't easily do without, but aren't available either.

I found this new clock/calendar UI pretty oversized.

Their not show unistall option, but can be “uninstalled” via powershell, in this link is a guide:

http://anoopcnair.com/2015/03/03/remove-uninstall-windows-10-modern-applications

But one thing is certain, whit uninstall option or not, no one of the preloaded apps can be removed, their are only disabled.

All those apps works without problem with a local account, only that when you open their for first time, you are asked to swich to a MSA or for login separately. Also I admit that is tedious.

for the mail app, at diference of the W8\8.1 mail app, not need any more of a MSA to run it. Anyway is a too basic app. You cannot print mails, you cannot merged diferent mail inbox... Except for the not need of a MSA to run it, is a total downgrade when compared with the W8.1 mail app.

The way that article reads, you first have to INSTALL the update - then if you "determine" the update "is causing problems" - THEN you can uninstall and hide it.

I'm basing that interpretation on the following from the article: If that's correct (you have to install first then uninstall and hide) - that is not acceptable to me. Will continue to pass on this.

I'm pretty much liking 10 so far, but for some reason shortcuts can't be pinned to the start menu (no Steam or Galaxy shortcuts for me I guess) and I can't stand that Windows now forces you to use Bing for search results. Fucking Bing! No one uses Bing, even Microsoft has to realize this.

Can you clarify what you mean by forcing you to use Bing! for search results? Do you mean if you search locally (like from the Start menu to find a program on the computer) that it actually produces Bing! results as well?
