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 lags

Hi,



Thank you for writing to Microsoft Community Forums.



We understand how difficult it is when the PC doesn’t perform the way it should be. We were checking the lag issue, but
in order to get clarity and to assist you accordingly, please reply with the answers to the questions below.

• What is the Windows 10 version and Build installed? (Type
  winver in Windows search/Run command)
  
• How much is the CPU and Disk usage showing in Task Manager, also check if any particular program is having high CPU and Disk usage?

We would suggest you to refer the steps as suggested in this article (Exclude step 10):
Tips to improve PC performance in Windows 10



Meanwhile, put the PC in Clean Boot and see if you still get the PC lagging issue. Refer the article

How to perform a clean boot in Windows. A ‘clean boot’ starts Windows with a minimal set of drivers and startup programs. If the settings app is working fine in Clean Boot then please refer the section
How to determine what is causing the problem after you do a clean boot
to determine the root cause of the issue.



Note: After you finish troubleshooting, follow the section
Reset the computer to start normally after clean boot troubleshooting
to reset the computer to start normally.
