اسکریپت powershell شامل یک تابع به نام Compact-VHDX است که می‌توان با استفاده از آن سایز دیسک‌های VHDX را که به صورت Dynamic تعریف شده‌اند و بیشتر از فضای واقعی درون آن‌ها را اشغال کرده‌اند را کاهش داد.
فایل VHDX باید حتما در ابتدا غیرفعال یا dismount شود تا اسکریپت powershell بتواند به آن دسترسی داشته باشد.
برای استفاده فایل زیر را از گالری Technet دریافت نمائید و مطابق راهنمای فراهم شده به شرح ذیل از آن استفاده نمائید.

NAME
Compact-VHDX
SYNOPSIS
Function to remove unused space in Dynamic VHDX file
SYNTAX
Compact-VHDX [-VHDXPath] [-SDelete] [[-LogFile] ] [-WhatIf] [-Confirm] []
DESCRIPTION
Function is designed to work on Dynamic VHDX files – not Fixed.
To reduce size of Fixed VHDX file convert it to dynamic first then use this function.
For example:
Dismount-VHD -DiskNumber 13 -Confirm:$false
Convert-VHD -Path ‘d:\Fixed1.vhdx’ -DestinationPath ‘d:\Dynamic2.vhdx’ -VHDType Dynamic
Where ’13’ is the disk number as shown in Disk Management/Computer Management.
Before using this script, empty space on the VHDX disk first by deleting un-needed and
temporary files, and emptying the recycle bin
