How can I update Windows 11 23H2 to 25H2 on my pc?

Using Deployment Image Servicing and Management (DISM) to upgrade Windows 11 23H2 to 25H2 is an advanced method that involves applying a mounted Windows image (ISO) directly to your current system. It’s a powerful technique typically reserved for IT professionals, but I can outline the general steps if you're comfortable with technical procedures.

Prerequisites

• A full Windows 11 ISO (preferably the latest 25H2 version)
• Backup your important data — this method carries risks
• Administrative privileges on your PC
• Enough disk space to mount and process the ISO

How Update Windows 11 23H2 to 25H2:
1. Download the Windows 11 ISO (25H2)
    Right-click the ISO file and select Mount
    Note the drive letter assigned, e.g., D:\
2. Locate the install.wim or install.esd file
    Usually found in D:\Sources\
    Copy this file to a working directory, e.g., C:\Mount\
3. Use DISM to apply the image
   Open Command Prompt as Administrator.
   Run commands like:

dism /Get-WimInfo /WimFile:C:\Mount\install.wim

Apply the image (this replaces your current Windows with the new image):

dism /Apply-Image /ImageFile:C:\Mount\install.wim /Index:1 /ApplyDir:C:\
