Win8 prompt "Install update immediately prompts to restart"

You may notice such a problem when using Windows 8, when the update patch is not obvious (only on the login screen with text prompts), after installing important updates A prompt will pop up asking for an immediate restart. Instead, the login screen tells you that it will restart after 3 days to complete the update installation. This less obvious hint often leads to a lag in patch installation, perhaps when you notice the text prompt, either the patch has been released for a few days, or it has reached the system-defined restart time.
I often ignore the restart after the patch is installed

For the desktop, you can also see the "Update and Restart" prompt when you shut down. If it is a notebook user, it is usually not very good. Shut down (close the screen directly to let the system sleep standby), it is even easier to restart the update patch in time.
You can know if there is an update when you shut down

So we need some means of solution.

Some time ago, Xiaobian introduced a small tool that can help you get the Windows 8 update in time (click here for details). The content that will be described today is how to install the update after Windows 8 for the first time. In a more significant way, let us know to restart the computer to complete the update.

Before proceeding, our Win8 system needs to update a patch first: KB2822241. This patch was released last week. If there is nothing unexpected, you should have already patched this patch. If not, check the update directly through the Win8 update.
You need to install this update first

After installing this update, you need to modify the registry file.

1. Press [Win+R] to start the “Run” box, enter regedit to run the registry editor;

2. Locate HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsWindowsUpdateAU;

: If you don't have WindowsUpdate and AU, you need to create these two items manually.

3, in the right panel of the AU item, find "AlwaysAutoRebootAtScheduledTime", if not, also manually create a DWORD and rename it.
Change this value to 1

4. Double-click the DWORD and change its value data to “1”.

5. Close the Registry Editor and restart your computer once you are done.

After the change, every time Win8 installs an important update, it will pop up a 15-minute countdown restart notification, and no longer need to wait for 3 days to notify you. If you don't need to pop up the notification immediately, change the above registry value to 0 to restore to the default setting.
