Its being rolled out in waves. Could be hours, days, or even weeks before it gets to everyone.

Nothing happening here, though I reserved a copy of Windows 10. Maybe in the next few days.

Does anyone use the 32bit version? Does anyone have less than 4GB of ram and is planning to upgrade?
What I wonder about is, if I don't like Windows 10, can I simply reinstall Windows 7 or will i "loose" my license?

It's good in a VM and if you're not using software that's compiled for a 64bit computer you'll get little if any benefit from the 64bit version.

A lot of those Windows 7 computers were sold with only 2gb of RAM, I have no idea how many of them are still around. Also, for what people typically do there's little reason to go 64bit, it just doesn't help that much with browsing the web or opening a wordprocessor.

Seen a post that shows an image when installing, stating you can downgrade within one month if you want to.

As for 32bit, I`m guessing with the lower requirements, it may help the older computers out.
Mine is 64 bit though, so safe there ;)
I`m guessing, but if you`ve still got the disc for current OS, you can just re-install it any time, unless windoze are going to block those keys afterwards.

*shrugs*

Still dubious about trying win10, I`m on mobile internot & having forced updates is a no go for me, especially if I`m playing some pvp online & that crap hogs the speeds.

Getting new gfx card some time this year, so perhaps may upgrade then...

I would disagree that there's little reason to go with 64bit. It's getting more common for even midrange graphics cards to have 1-2GB of RAM, which seriously cuts into and slows down 32bit versions of Windows. I have so many tabs open at times that my browser can use upwards of around 2GB of memory at any given time. Now I might be in a minority of people that browse that way, but still, I say having at least 4GB of ram and using a 64bit OS is a pretty big deal even for average users.

One of my friends who's not very tech savvy always complained about how slow his computer was. He upgraded to 64bit and he felt like he got a brand new computer. If VRAM didn't count towards the 32bit ~4GB ram limitation, I would be more inclined to agree with you.

Edit: Also, even a lot of modern games use 2-3GB of RAM, which when combined with the VRAM on a modern video card, would essentially bring a 32bit OS to a grinding halt. I'm actually using 3.51GB of RAM right now and I'm hardly doing much at all compared to do what I normally do.

Hmm, well from what I've been reading, people have reported that if they aren't in front of their PC to delay the reboot when it auto-updates, then Win10 will reboot the PC anyway. Is that incorrect? That's why I say that could be a huge deal to people who run servers or have their PC perform time-consuming tasks like video encoding while they are away from the computer.

Well, that's good that it still gives you the option to revert. Still a big question mark though about what happens to the licenses. I'd hate to permanently lose an expensive Windows 7 license if I didn't end up liking Windows 10.

I think maybe you didn't understand my question, but your last statement might answer what I was trying to ask. As long as the Windows 10 key that you get when you upgrade is considered a 'full-version' key, then there would be no issues for me with that. But there's no way in hell I'm trading in 'full-version' keys of Windows 7 that I can use to perform clean installs on any computer I want (as long as it's only on one PC at a time), for an 'upgrade only' key that I won't be able to use if I build a new computer or something like that. That seems more like 'downgrading' than 'upgrading' to me.

I'm still open to the possibility of upgrading to Win10 though this year, just depends. If they eliminate forced auto-updates then I'll be much more interested in upgrading.

No idea. Haven't had an update that required rebooting yet.

From the Windows 10 FAQ No idea how the activation method is. Will have to dig through MDL later this month to see if more info is available, and whether you can use said keys on other machines or not. But clean installs on the same computer are definitely possible, and probably possible on other machines as well.

It seems like you're making assumptions about what people do with their computers that are probably not valid for most computer users. Most computer users use email, maybe youtube and a few other things of similar performance requirements. A computer from 10 or 15 years ago could have handled the load that a typical user places on their computer. Albeit in a less efficient manner.

I'm more of a power user, so the trade off makes more sense. But if I look at my computer right now, I'm using about 1.8% of my processing power and about 90% of my RAM. And that's fairly typical when I'm not running VMs or doing anything particularly intensive.

Here are my impressions with Windows 10 RTM:

The Good:

* DirectX 12 and better usage of multicore processors.

* Windowed modern/universal apps.

* Start menu return (personally, I don't like to have everything cluttered in a corner with ant-man sized icons, but the majority likes that way, so here it is), you can choose between the start clutter and full screen menu from Settings

* Notification center

* Better multitasking (virtual desktops, better DPI scaling and enhanced snap -4 corners and 2 sides, previously you could snap to only 2 sides-)

* Powerful and efficient search feature

* New calendar and clock interface, also for networks and volume (the latter lacks a direct access to the mixer)

The Bad:

* In theory, the requirements are the same as Windows 7 & 8.x, but at least on my test rig, it uses more ram than normal, while idle, it uses 1.2GB while Windows 7 used 900MB and 8.1 used 800 (to be clear, 1.2GB after disabling Superfetch, because it has a memory leak and usage skyrocketed to 2GB on idle, I'll talk about this later).

* Forced updates: (makes sense for security ones, leave alone optional, drivers and third party software) this is already causing a lot of headaches (Microsoft released an utility to hide unwanted/problematic updates, but that's a palliative, not a cure)

* Dumbed down control panel: the new control panel aka Settings is very limited, sometimes I even feel that Android settings screen has more options... totally forced updates without any detail about them, no references, no download size and remaining time, just their name and a global progress percentage.

* File association options are very bad, by default all files are opened with the modern apps (if people didn't want modern apps on 8, probably will not want them here), the new control panel lets (in theory) to choose default programs for certain general actions (music player, video player, web browser), but it doesn't always work and you will find out that even after setting a desktop program to open files, a modern app will open instead, at least there's a link to the old (and mutilated) control panel section to set associations the old way, (but some associations will not change, a modern app could have the priority).

* By default, you're a P2P node, that means you can download updates not only from the Microsoft servers, but from other users as well, you'll also upload data so others can download from you, like Torrents, you get it?, the bad thing is that you can't control the bandwidth it will use, by default it eats all of it and interferes a lot when playing online, it can be disabled, but it shouldn't be turned on by default in first place.

* Unremovable preloaded apps: personally I don't use the contacts app, neither pictures, groove music or video and movies ones, why I should keep them if I don't like them, they are unremovable and interferes with file associations, I've tested them, tried Groove Music for a couple days, but seeing it take 200MB of RAM to play a single song, while WMP did the same with 12 and AIMP3 with 6, it's disappointing, also add that modern/universal apps could hibernate at system discretion, that is very irritating.

* Some bugs reported by insiders still made their way to RTM , the worst one is a memory leak related to Superfetch feature, it can be solved by disabling that feature, I still haven't experienced problems by doing so, but if it was there it's for a reason (it was already on 7 and 8.x and never gave problems there) Microsoft put deaf ears on this, a bad gesture when you claim that you hear from the community.

The Ugly:

* Icons: a lot of Vista/7 era icons (and a handful of 98, ME and XP ones) are still there, there are also lots of icons updated inside some system files, but they weren't applied to other system parts.

* Blur effect tied to start menu settings: blur effect is beautiful, but also a resource hog, if you use the full screen start menu/tablet mode and want to have it with a background, you must leave it turned on, these settings should be separated, but Microsoft didn't care.

* System almost begs you to ditch the local account in favour of a Microsoft one (this messes up local network shares) but some apps will not work well or will not work at all without it (mail, phone companion, windows store)

Can you also have both at the same time or is it either or? And can you remove all tiles from the start menu to make it look more like the old one?

Control Panel is still there, under the name of Control Panel. All the options are there.

When installing, you are asked if you want to use the built in apps or not, and it does remember the previous settings. Music and video is opening with VLC for me, pictures with Irfanview, webpages with Iron, mail with Outlook.
No idea. My Win7 key is a SLIC one, so it remains a Win7 SLIC key even with Win10 running.

Holy crap. What if I'm traveling and I don't want to use up my 3G stick's download quota? Mandatory automatic updates is just crazy. I think I might as well stay with Windows 7 for now.
