how to update window and why update installing pending ?

To update Windows 10 and understand why updates are pending, follow these steps.

1. How to update Windows 10

1. Select Start.
2. Go to Settings > Update & Security > Windows Update.
3. Select Check for Windows updates.
4. If updates are available, select Download & install.
5. If prompted, restart the device to complete installation.

This keeps the device running smoothly and securely. Note that free security and feature updates for Windows 10 end on October 14, 2025, after which moving to Windows 11 is recommended.

2. Why updates show as “installing” or “pending”

Windows Update works in stages:

• Downloading: The Windows Update Orchestrator determines which updates apply and downloads them in the background. Delivery Optimization is used to reduce bandwidth impact on other downloads.
• Installing: After download, Windows creates an “action list” of files and passes it to the installation agent (such as CBS or Setup) to install. During this time, status may show as Installing or Pending install.
• Pending restart / commit: Many updates require a restart to finish. Until the device is restarted, updates may show as Pending restart or Pending install. The Orchestrator can automatically restart based on configured settings, or the restart can be done manually.

Updates can remain pending if:

• A restart has not been performed yet.
• Active hours or restart settings are delaying the reboot.
• Windows is still downloading or preparing the update in the background.

To complete pending updates, restart the device from Start > Power > Restart, then check Settings > Update & Security > Windows Update again until no more updates are listed.
