Microsoft releases new security patches for different versions of Windows 10 every second Tuesday of a month. If you want to avoid any vulnerability that appears from time to time, you must download and install these cumulative updates. But at times, Windows update fails and rather displays error code 0x80070BC9. This bug usually comes along with an error message that reads the following –
0x80070BC9 – ERROR_FAIL_REBOOT_REQUIRED. The requested operation failed. A system reboot is required to roll back changes made.
There are several reasons that may cause this issue on your computer. Out of them, the most common issue is the stopped Windows Modules Installer service. Go and check the current status of this service and in case you find this service, change its startup type to “Manual”, and start this. Corrupt Windows update folders and problematic installation of new programs may also cause this error. In this tutorial, we have discussed five checks that you must ensure in order to get rid of this persisting error. Let’s explore them in detail –

Whenever a new security/non-security patch gets released for Windows 10, Microsoft also provides a standalone package for the corresponding update at the Update Catalog site. All you require is to visit the official site, download the standalone packages, and manually upgrade your computer to the latest OS build version.
