I believe many users want to try out the new interface design of Windows 11. However, upgrading now is a bit risky, and you may encounter many bugs or software support issues. In fact, there are other ways to pseudo-experience it, which is by changing the Windows 10 theme and icon. This article will teach you how to operate it.
Also, let me remind you that there are a lot of steps and it will take some time.

Step 7 – Install Classic Shell
This set Classicshell The software can hide the original Windows icon in the lower left corner and click Download Now on the screen to download:

Step 8 – Download Center Start Menu
The next step is to make another start function icon that can be placed in the toolbar, please download Center Start menu, and put the folder in the C slot after decompression:

Enter the center start menu folder and transfer Start.exe to the desktop as a shortcut:

You can delete the shortcut to the name and open the right-click menu:

Check the box below to replace the Start button and select Customize –> Pick an image:

There is also an empty.png found in the center start menu, please select it:

Then the Windows 10 start icon in the lower left corner disappeared:

If you want to open the Start menu later, click on the Windows 11-like Start icon, and it will still open from the left:

Step 10 – Center the application icon via the link function in the toolbar
Before enabling the link function, please uncheck all display options, as shown in the figure below. Right-click on the toolbar to open this menu:

Windows 10 searches are also hidden:

The toolbar will now be very clean:

Then please open the toolbar –> link:

A “Link” will appear on the far right side of the toolbar, please drag the “||” on the left:

After moving to the far left side of the toolbar, you will see that all icons will come out from the right:

As shown in the figure below, drag the || on the left side of the application icon and move it to the middle of the toolbar:

Like this, I forgot to install UltraUXThemePatcher at the beginning, so the icon was not centered when Windows 11 started. Logically speaking, it will be automatically centered. You can refer to the first picture of the article:

After the position is fixed, check the lock toolbar so that || will disappear:

As shown below:

That’s it for all the steps, it takes a while to set up.
