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

Can't Unlock BitLocker Encrypted Folders Windows 10

So I have a few folders that I have encrypted with BitLocker which are on a secondary drive. I encrypted those folders using Windows 10 Enterprise and I have the key for it, but I can't seem to find out how to unlock it using my Windows 10 Home. I can't
use any of those files inside the encrypted folders. The entire drive is not encrypted. Just two folders which contain subfolders and files.
