Let’s discuss How to Automate Time Windows Update Reboots with Intune. Scheduled Install Day Policy setting is part of the Update rings for Windows 10 and later policy in Microsoft Intune. It allows administrators to specify the day of the week when automatic scheduled reboots for Windows quality (monthly) and feature (semi-annual) updates will occur.
This policies function is to Defines the day of the week when updates are automatically installed and the device performs a scheduled reboot to complete the installation if no user is present. When a Windows Update (quality or feature) is available, Windows downloads it in the background. The update installation may occur automatically.
If the device is configured to use this setting, Windows will attempt the final installation and mandatory reboot during the Scheduled Install Time on the specified Scheduled Install Day (e.g., 3:00 AM every Sunday). If the device is being actively used by a user, Windows will typically prompt the user with notifications and attempt to respect Active Hours before performing the mandatory, scheduled reboot.
By enabling this settings, admins can minimize user disruption. By setting the install day to an off-peak time like Sunday at 3:00 AM IT ensures the required reboot happens when virtually no users are working, preventing unexpected reboots in the middle of a workday.

Sign with Intune Portal
As an Admin you can easily configure this policy on your tenant. For this Sign in to the Microsoft Intune Portal with Credentials. Navigate to Devices > Configuration > + Create > New Policy

Profile Choosing Step
After that you can choose appropriate platform and profile type. This is necessary step for policy creation and you cannot change profile and platform after creating profile. Here I would like to configure the policy to Windows 10 and later platform and settings catalog profile. Then click on the Create button.

Begin Policy with Basic Tab
Basic Tab is the first tab that helps users to give identity for policy. For this you can add Name and description for the settings you want to select for policy creation. Here is Name is mandatory and description is optional. After adding this click on the Next button.

Configure Enterprise Proxy Servers Policy
After that you will get Configuration settings tab which helps you to access specific settings. To get the settings click on the +Add settings hyperlink and select specific settings from Settings Picker. Here, I would like to select the settings by browsing by Category. I choose Windows Update For Business. Then, I choose Scheduled Install Day settings.

Add Value
To specify a day for Update Installation you have 7 days like Sunday to Monday. Here i would like to choose Sunday for Update Installation which is most common choice for corporate devices. Because, Sunday night/Monday morning is the lowest-use time for most businesses, ensuring the device is ready before the start of the work week.

Adding Scope Tags
Scope Tag is not a mandatory step for policy creation. But you can add Scope tags for visibility restrictions. Here, I don’t add scope tags for Enterprise IP Range Policy. Click on the Next button.

Selecting Group from the Assignment Tab
To assign the policy to specific groups, you can use the Assignment Tab. Here I click, +Add groups option under Included groups. I choose a group from the list of groups and click on the Select button. Again, I click on the Select button to continue.

The Review + Create tab is the last step of policy creation. On this tab, you can verify every detail of the policy which are added in the previous steps (basic configuration settings, scope tag assignments s etc). If you want to make any changes, click on the previous button; otherwise, you can click on the Create button.

Device Check-in Status Page shows if the Policy is succeeded or Not. Before checking this, you can sync the device on Company Portal for Faster policy deployment. Then Go to Devices > Configuration > Search for the Policy. Here, the policy shows as successful.
