Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

Buying Windows 10 questions...

So, I want to buy a copy of Windows 10. I used to do it in retail stores in the past, but now I want to do it online. It seems cheaper as a download, but I'm wondering few things which are a bit confusing...

Windows 10 Pro
http://www.microsoftstore.com/store/msusa/en_US/pdp/Windows-10-Pro/productID.319935900

"Buy Windows 10 (Download)" option down below.

So, this is what I want to buy. How do I know what type of Windows is this (apart from knowing it's a Pro version)? It doesn't say whether it is 32bit or 64bit so I'm assuming it will give me both. It also doesn't say if this is a full version that I can re-install countless times on countless new motherboards/CPU's/disks opposed to OEM/DSP which have limited number of activation and you can't transfer them across different hardware. OEM/DSP can usually only be bought with new hardware/computer.

So, I'm assuming this is the actual full fat Windows 10 Pro 32bit/64bit that I'll be getting. Am I correct?

Also, can I buy it in Microsoft Store US opposed to my local one? The price difference is stupendously high.

Thx for help

 

DOWNLOAD WINDOWS 10 NOW - Upgrade and ISO direct from microsoft

Click to expand... Yeah I went to that site, why do I need to buy a key?
I won't buy a key, stupid.

I'll revert back to windows 7 then.

When I still was on windows 7, about a year ago I added 4GB extra ram which is a total of 8GB now,
is that causing the problem?
