After installing the cumulative update KB5034765 for Windows 11 versions 22H2 and 23H2, which I introduced last time, I encountered an issue where the desktop and taskbar were slow to display, but I found a solution.
Is Win11 KB5034765 frustrating? Fixed issues and new ones
After installing KB5034765, the Copilot icon will be moved to the far right of the taskbar, instead of next to the Start button.
This feature is currently deployed in select environments and will be gradually rolled out to consumers using a Controlled Feature Rollout (CFR).
When the Copilot icon is placed to the far right of the taskbar (new features enabled), the desktop and taskbar display is slow due to Copilot-related registry values.
In my previous article, I mentioned that the time it takes from the Welcome screen when signing in to the desktop appearing, and from the desktop appearing to the taskbar appearing, is slow. However, it's not the Welcome screen that's slowing down the startup of File Explorer itself when starting up your PC.
In my environment, if I left the sign-in screen for a while, everything was displayed when I signed in.

There is information (not certain) that Microsoft has changed KB5034765 to a newer version on the server side, but reinstalling KB5034765 does not seem to resolve the issue in many cases.
If you are currently experiencing this issue, uninstalling KB5034765 and then reinstalling it may resolve the issue.
[Solved] Can't uninstall Windows updates? A detailed explanation of the causes and solutions
If reinstalling doesn't solve the problem, try the following:
How to resolve the issue of slow desktop and taskbar display after installing KB5034765
This is a solution that I have tried and found to work.
Either Registry Editor or Terminal (Windows PowerShell) is fine.
Method 1. Registry Editor
If you operate the registry incorrectly, it may cause problems such as the system being unable to start. Please make a backup in advance using system restore or similar, and proceed at your own risk.

1. Press Windows key + R to open Run, type "regedit" and press Enter.
2. The Registry Editor will open, so open the following key:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Copilot\BingChat
3. With the "BingChat" key selected, double-click the value "IsUserEligible" in the right column to open it.
4. Enter "0" in the Value data and press Enter.
5. Exit Registry Editor and restart your PC once.
When the PC starts, the value data of "IsUserEligible" will return to "1", but the issue of File Explorer itself starting slowly when the PC starts up will be resolved.
Method 2. Terminal (Windows PowerShell)
This does the same thing as the registry operation above.
1.Start buttonRight-click and click Terminal (Admin).
2. The User Account Control window will open, so click "Yes".
3. Once the Terminal (Windows PowerShell) opens, type the following command and press Enter:
Copy the code and right-click on the terminal to paste it.
reg add HKCU\Software\Microsoft\Windows\Shell\Copilot\BingChat /v IsUserEligible /t REG_DWORD /d 0 /f
4. When you see the message "This operation completed successfully," close the terminal and restart your PC.
When the PC starts, the value data of "IsUserEligible" will return to "1", but the issue of File Explorer itself starting slowly when the PC starts up will be resolved.
