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

Windows 10 Windows Defender versus Microsoft Security Essentials

Hi Bryan,

Microsoft Security Essentials was upgraded to Windows defender and it was a default security software from Windows 8. You cannot have both as they are one.

Since you get this annoying popup at the startup i suggest you to disable any Microsoft Security Essentials entries in Startup tab.

• Open the Task manager. by pressing Press CTRL+Shift+ESC.
• click on Startup tab
• Right click on Microsoft Security Essentials entry and click on Disable.

Restart the computer and check if that helps.
