Windows 10: Slow Windows 10 response after KB5027215 or KB5028166

Hi all,Last month after installing security update KB5027215 our computers started to operate very slow. Opening the start button takes long time to respond, launching programs takes long to react like opening command prompt and all other operation, Uninstalling this KB restored the normal Windows operations and the fast response.Waited the July security update, KB 5028166, and after applying it the slow performance returned like last month - for example, launching a command window that about 25 seconds until it opens and the same for about anything else to be launched.Of course, uninstallin

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
