# Hotplug Memory Reporting Mismatch in Windows Guest OS

## Problem

* When configuring Hotplug memory in a VM, the memory reported inside the Windows VM shows the maximum hotplug range instead of the configured hotplug memory value.
* Example: With Hotplug RAM = 8 GB and Max Hotplug RAM = 64 GB, the Windows VM reports 64 GB instead of 8 GB.

## Environment

* Private Cloud Director Virtualization - v2025.4 and Higher
* Self-Hosted Private Cloud Director Virtualization - v2025.4 and Higher

## Cause

This is a reporting mismatch inside Windows guests when the configured Hotplug RAM is less than the Max Hotplug RAM.

* The VM is presented with the maximum hotplug range, which Windows reports as total memory.
* Actual usable memory remains aligned to the configured hotplug value but may not be correctly displayed in Windows Resource Manager.

## Workaround

* In some cases, performing a VM reboot may help the guest OS reflect the correct usable memory.
* If the issue persists, a practical workaround is to configure the VM with *Hotplug RAM = Max Hotplug RAM* so that Windows reports the expected value.

## Additional Information

This behavior is currently under review by the engineering team, and the enhancement is planned to be available in future releases of PCD under **PCD-2855**.
