In this website we can see that W7 pro is able to manage (physically) 192Go of RAM. (I'll talk only about x64)
http://msdn.microsoft.com/en-us/library/windows/desktop/aa366778(v=vs.85).aspx#physical_memory_limits_windows_8
But we know it's a lie because the OS don't accept to manage that much. I can't have 32Go of RAM on a windows 7 pro, the OS will not use everything, I'm right? It will limit to 6Go I think, maybe 8Go.
So I would like to know about the windows 8 pro version, how much RAM can be managed by the OS?
This question is to know if it's useful to have 32Go of RAM or if 16Go are enough, because I don't think that W8 Pro will manage more than 16. But I don't remember where I learned that.
There is any change with windows 8.1?
Thank you.
The Core Edition of Windows 8 can handle 128 GB and the Pro/Enterprise can handle 512 GB of physical RAM. This is explained in the link you posted.
In a stock Windows installation, the OS limits your ram for some reason. The way to change it is tucked away in the settings:
Use the shortcut "windows button" + "r" to bring up the run window, then type in "msconfig", then go to the "boot" tab, then click "advanced options", and finally uncheck "maximum memory" and click apply. Now reboot and enjoy your full amount of ram.

So I took my laptop (a Lenovo Yoga 2 pro) in to best buy after it had water spilled on it. They said they'd fix it under warranty and I left it with them. A few days later I came to pick it up, but with only one problem. I gave them the laptop with windows ten as it was installed during the free upgrade period. I got the laptop back with windows 8. Best buy basically said tough titties and told me they couldn't do anything. Would I be able to install windows 10 to it with no problem, or would I have to buy a copy. I heard you can install it and use the windows 8 key it came with.
What does everyone think?
So far I know, you can activate and install Windows 10 with the key of your old Windows version only if it's the one with which you upgraded to Windows 10. However it could be also possible to use other keys according to this link. Here is also shown how to reinstall Windows 10.
How to reinstall Windows 10 with your old Windows 7/8/8.1 key
Anyway because it's Windows 10 you also have a digital license which is linked with your account. So it's also possible to reinstall Windows 10 without a product key requiring only to log in with your Microsoft account. You can read yourself, just scroll to the section where it's about how to activate after reinstallation.

This is part of a migration from Vista to Windows7. I now have a dual boot computer, with Win7 the preferred OS. From time to time I might need to go back to Vista to see how the things were configured there and then I will need to go back to Win7 to configure/install the same app there.
This is a computer that had very complex settings and it was difficult and risky to upgrade in place, to install Win7 over Vista.
In order to avoid countless reboots I would like to be able to always run Win7 and when I need I would like to be able to fire up VMWare Workstation and to start a Vista Machine that would have as HDD the physical HDD where currently Vista resides. I would expect the VMWare machine to run the OS installed on that HDD and I would expect Vista no to see that the hardware changed. My apps are not hardware dependent.
Is this possible?
Its possible and there are a few ways you could go about doing this.
The Easy Way
VMware Desktop allows you to use your existing partition/Disk to boot from only if its an IDE Disk.
https://www.vmware.com/support/ws5/doc/ws_disk_dualboot.html
The hard way
You can capture the Windows Vista OS as an .wim image with Windows Deployment Tool ImageX.exe. Then use other tools to create a bootable ISO. You would have to update the image though every time you feel there are a lot of changes made in Vista you want to see in VMware.

everyone!
I need your help!
I am running Windows 8.1 Pro x64.
I reinstalled it, but the problem is remaining.
BSOD happens about 1-2 time in a day.
I noticed that if it happens, it frequently happens in few minutes after I start to download something using "uTorrent".
Motherboard: "Asus M4A78LT-M LE". My network driver: "Qualcomm Atheros AR8131 PCI-E Gigabit Ethernet Controller (NDIS 6.30)".
I tried to install an old version, but the problem did remain.
My UAC and Windows Defender are off. Firewall is on.
Here's a link to some info I extracted:
http://www.beetxt.com/printable.php?view=ydP
(sorry it's in russian, cause I have russian Windows)
Here are the dump files (they are in .rar archive):
https://drive.google.com/file/d/0ByigE0NW6WLIaUpKSkgtcnFqR1E/view?usp=sharing
Thanks for the attention!
If it comes up again, it's probably L1C63x64.sys, not tcpip.sys. It's the driver of your qualcomm card, shows up in the stack of two of your minidumps just before tcpip.sys. Its timestamp is April 01 2013, while there is supposedly a newer one on your motherboard's support site, updated at 2013/09/30.
Another option is giving a shot to an unofficial driver, as a last resort solution.
Check Windows Event Log for events near the BSOD time. You are having a problem with tcpip.sys driver.

I recently had to enable VT for windows7 since I want to run ubuntu on vmware so I was wondering why isnt it enabled by default is it some kind of security issue or just not necessary for the average user?
There are several reasons, including "security" and "performance":

Intel virtualization technology can get hardware intensive and although the software requirement is low (Windows Vista) only modern CPUs made by INTEL ONLY such as Intel i7 support it.
Not all windows computers have an Intel CPU though (a good amount of them do). The only people that use the VTX technology are developers and people who want to run a different operating system than their computer came with, so not everyone. As for security issue, I'm not sure but it can get very RAM intensive. (i.e. the Android HAXM for developers has a default RAM usage of 2GB, and the minimum is 512 MB!).

I don't understand that StackExchange, where I can post question about computers, so I think, this will be good.
Friend of mine wanted to reinstall windows and clear everything. He had windows XP. He don't know a lot of computers, so I decided, I will do that. I took his HDD to home and connected to my computer. Installation of windows XP started and everything worked well.
But when I bring HDD back to his computer and connected it, all I get after start computer is that (picture bellow). It is something like cursor, flashing on screen and never end. Does someone know, what could went wrong, when that worked well in my PC and its same windows, which he had before? (Sorry for bad english)
Windows is configured based on the hardware underneath. Installing windows in one system and then placing the HDD in another usually does not work. Use a Bootable USB to install Windows in the system as the DVD Drive isn't functional.
