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

Migrating a Windows 10 installation to a new SSD drive

Before I ask my question, I've read
this post so I understand the basic procedure.

My exact situation however is that I intend to keep the existing drive with Windows on it installed, but just transfer my Windows installation to a new SSD that I plan on installing. What do I do with the old installation once Windows is installed on the
new SSD because there will be stuff still on the existing drive that I want to keep on there? Is it easier to migrate the entre contents of that drive to the new SSD (it's a 500GB drive and I have less than that on my current HDD) and format/partition to clean
that HDD once that is done? If so, how?

Any advice would be appreciated.

 

Need to migrate Windows 10 installation to new SSD , it's a mess.

I did the Diskpart step that SWI2 explained in post #14 and rebooted, but I still see drive D having the system label.
