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

Activation of Windows 10 on new PC

I've recently built a new computer and am trying to activate Windows 10 on it. I have a digital licence that's tied to my Microsoft account, but when I try to go through the activation steps via the "My hardware recently changed" option, it doesn't show
my new computer on the list, though it does show the old one I'm trying to transfer the licence from. I have signed in on both with the same Microsoft account, and both are listed as devices connected to my account. I've tried signing out of my Microsoft account
and back in on both of them, to no effect. It was a free upgrade from Windows 7, but I made sure to activate it to tie it to my account.
