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

Enable or Disable Microsoft Edge Tab Preloading in Windows 10  

OK, I understand that I cannot find the entries in the registry because the default settings doesn't have them, i.e. they haven't yet been created either via GPEdit or .REG file.

Discussing just Option 2 (Enable or Disable Microsoft Edge Tab Preloading using a REG file), I also understand that the .REG file in step 3 creates a key/value entry under HKEY_LOCAL_MACHINE which has the effect of 'Disable Tab Preloading'.

What I don't understand is why - in step 2 (Enable Tab Preloading), i.e. to revert to default - the .REG file removes keys under both HKEY_CURRENT_USER and HKEY_LOCAL_MACHINE.

Why would there be a need in step 2 to remove a key under HKEY_CURRENT_USER (to revert to default) if step 3 didn't create the key/value under HKEY_CURRENT_USER in the first place?
