How to Protect Your PC From Windows 11 Cumulative Update Failures

Cumulative updates are patches that Microsoft releases frequently, on a monthly basis. While it's good practice to install them for the sake of both security and performance, the downloading and installation process can get interrupted or paused due to various factors. Some people might get lucky and solve the issue by simply resuming or restarting, but others might experience a severe shutdown or even a complete freeze.

It is much more important and useful to have a working system backup image in place than trying to fix a failed update.

Backing up the state of your working system, as well as your programs and data, guards against operating-system crashes, data loss, and worst-case scenarios requiring disaster recovery.

The tool called Todo Backup Free can take care of most of your backup needs with its powerful features, allowing you to save backups to physical disks, network drives, NAS, and the cloud.

Create a bootable rescue medium before you make your first backup. This enables you to perform system or data recovery even if your computer is no longer accessible.

Step 1: Grab a USB drive that you can write to.

Create Emergency Disk

Step 2. Start and install Todo Backup on Computer B.

Step 3: Click on Tools and then select Create Rescue Disk.
