Windows 11 - Fix Calendar flyout is slow, not working & other issues!

Windows 11 is still in the Beta stage, even though Microsoft claims it is stable. We strongly believe it still has many bugs, making it more unstable than Windows 10.

Calendar flyout is also one of the flaws in Windows 11 which is present in Windows 10.

It is not actually a Calendar or Clock app issue, it's related to the notification center. Some people need help with calendar flyouts being slow or not working!

How to fix the Slow Calendar flyout or not working issue on Windows 11?

Before getting started with the guide, check the issue's root cause. Why the Windows Flyouts are not working or are slow.

Why is Windows 11 Flyout so slow?

The potential reasons for the calendar flyout problem could be

• A Notification center is disabled
• An issue with the Clock app
• Your PC/Laptop's low-end hardware
• Buggy Windows 11 build

Reason can be anything, you never know what will be the exact reason behind the issue.

First, identify that and apply it according to that root cause.

Method 1: Reinstall the Clock app

In this method, we'll reinstall the Clock app from Windows 11. It will not only reinstall Clock but also other Taskbar apps and utilities.

1. Close all the apps or perform a reboot that will close all running services

2. Run the Powershell as Administrator

3. Now, type the following command in Powershell

Get-AppxPackage -allusers Microsoft.WindowsAlarms | remove-appxpackage

It will remove Windows Clock from your device for all users. and we'll need to reinstall it from the Microsoft store.

Just visit the MS Store and search for the Clock app from Microsoft. It will install a clean and fresh clock app.

So, reinstalling the Clock app will fix most of the issues of the Clock app.

Method 2: Repair the system using SFC

If the previous Application-specific repair utility is not working, you can try to run the system repair using SFC commands in CMD or Powershell.

1. Open CMD or Powershell with Administrator rights

2. Enter the following commands one by one

sfc /scannow

Dism/Online/Cleanup-Image/RestoreHealth

It will take some time to do the System files Cleanup. It may take 30-60 mins according to your system hardware and file structure.

Method 3: Update Notification center values from Windows Registry

Sometimes, issues are caused because of Notification Center is disabled by default in the latest Windows build.

We need to enable it from the Windows Registry.

Open Windows Registry by searching Regedit in the Run program

Now, it will open Windows Registry and you've to follow the path - HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\Explorer

Set the value of the DisableNotificationCenter flag to 0 and reboot the system

Method 4: Manually Reinstall Windows 11

If all the previous fixes are not working in your case, you can simply reinstall the fresh Windows 11 build again.

Mostly it will fix the issue because we're resetting all the files to the factory-released package.

Pre-requisite before reinstalling Windows 11:

• Take backup of files and apps, you can backup it to your external storage or cloud backup

• Download the ISO from the Windows official download page

You can download the file from any option - Create Windows 11 Installation Media or Download Windows 11 Disk Image (ISO) for x64 devices

Once, you are ready with all the pre-requisites, we'll start the process of applying. We'll just give a brief overview of what steps to follow:

1. Run the Windows 11 iso exe file and Hit Next

2. Now, accept the agreement and proceed

3. Provide the required details and select a USB drive to create a bootable USB Windows 11(Use 16 GB USB if possible)

4. It will download and install the Windows 11 files on your USB stick and once, you complete the process, just reboot the device

5. Now, boot from your USB in the Boot menu of your PC/Laptop(Press F2, ESC, F9, or F10 depending on your PC/Laptop manufacturer)

6. Now, Hit Install now and just select the preferences, installation drive

It will install the Windows fresh copy of Windows 11. Just check whether the Calender flyout menu issue is fixed or not.
