 # How to merge checkpoints that have multiple differencing disks

-## Introduction
+## Summary
 
-This article describes methods that you can use to merge checkpoints into a virtual machine (VM) if Hyper-V has generated many differencing disks. The method that you use depends on the details of the situation.
+When you work with Hyper-V checkpoints, you might need to merge the associated differencing disks back into the virtual machine (VM). In most cases, you can delete checkpoints by using Hyper-V Manager, which automatically merges the differencing disks. However, in some situations—such as when third-party backup software creates checkpoints but doesn't clean them up—you might encounter checkpoints that don't appear in Hyper-V Manager or that can't be deleted through the standard interface.
+
+This article describes how to:
+
+- Delete checkpoints and merge differencing disks by using Hyper-V Manager.
+- Merge differencing disks when checkpoints aren't visible in Hyper-V Manager.
+- Use PowerShell scripts to merge differencing disks without shutting down the VM.
+
+Choose the method that best fits your scenario based on whether the checkpoints are visible in Hyper-V Manager and whether you can shut down the VM.
