I changed taskbar icons size but now having issue with the date, time and date in Windows 11

I resized my taskbar from the registry but now i am facing some isssue because the date, time and date are not resized properly basically the right side of the taskbar has not resized itself please help me!

Yeah, the registry hack causes that problem, and, the "small" taskbar height is still much bigger than the smallest that is possible on Windows 10. I tried ElevenClock, which, although it solved the problem of the maligned clock on the Windows 11 taskbar for me, was unable to let the clock on the main display device show seconds. The inability to use Taskbar Toolbars on the Windows 11 taskbar was yet another reason why I finally decided to bring back the classic taskbar of Windows 10. This can be done by using the UndockingDisabled registry hack AFTER installing Open-Shell (former Classic Shell) or similar, as this registry hack causes the Start Menu to be lost, but there are several other negative side effects that also are caused by this same registry hack. Finally, I found that ExplorerPatcher (available from GitHub) is the best solution by far. It has quite a few extra features, and it lets you continue to use the Start Menu of Windows 11 if that's what you prefer, or use Open-Shell anyhow (or the combination of both, as Open-Shell has a "Controls" tab in its settings where you can choose which action should open which menu, so there are plenty of options there).

That is the price you pay for using hacks, I don't think there is an easy solution to this unless you use software which may change other things as well

you must used hacks for smaller icons in taskbar...
open regedit => Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced
then in key TaskbarSi value change to 1...
1 is default value.
