DevExpress TreeView disable expanding circles ripple effect when expanding nodes

When you click a treeview node in the DevExpress treeview using many of the built-in themes you notice that a circle expands outwards in a ripple effect.

This is part of the CSS built into the theme and cannot be disabled for this control.

You can prevent the ripple by overriding the CSS.

For the default material compact theme the following resolves the issue.

        .dxtvControl_MaterialCompact .dxtv-elbNoLn::before 
        {
            content: none;
        }

Windows Server 2016, 2019, 2022, Windows 10 and Windows 11: Date and time "Some settings are managed by your organization".

Image
When you're using the new "Modern" date and time settings in Windows Server 2016, 2019, 2022, Windows 10 and Windows 11 you may find that you can't set the correct date and time and the value "Some settings are managed by your organization". - While you're here - Why not check out our Windows Server Documentation and Audit Tool? The simplest way around this is to go back to the proper control panel using Start, Run, "Control.exe" and searching for "Set the date".  Within here you can set the date and time manually as required If you try and click the Change time zone button you may again get access denied... To resolve this open an elevated command prompt by right clicking the command prompt and selecting Run as Administrator  From there run the command rundll32.exe shell32.dll,Control_RunDLL timedate.cpl This will open the Data and Time control panel app elevated as an Administrator.

Enable function lock for F1-F12 on HP ZBook mobile workstations

Image
When you press the function keys on a HP ZBook mobile workstation you may find that they don't operate as expected. This is because of function lock, if you hold the fn key the function keys work as expected. You can lock the function keys on as described in this document. https://support.hp.com/gb-en/document/c02035108 However there are two things to note Firstly following a BIOS upgrade (which occurs automatically if you have the preinstalled HP software still installed) you may lose your locked function keys and have to reapply.   Secondly the HP documentation states you press the fn lock and fn keys at the same time as per the image below from the page.  While you're here - Why not check out our Windows Server Documentation and Audit Tool? This is not the case, you need to press and hold the fn key, and then tap the fn lock key to toggle function lock, not an obvious thing when you start work first thing in the morning and are hammering the function keys try
