However, there are some creative workarounds that allow you to run Windows-like operating systems on your PSP. One such option is to use a custom firmware, such as the PSP CFW (Custom Firmware) or the HENKaku exploit.

While it’s technically possible to download and install Windows 8 on PSP, it’s not a straightforward process. You’ll need to install custom firmware or an exploit, convert the Windows 8 ISO image, and transfer it to your PSP. Even then, you may encounter performance issues, compatibility problems, and stability concerns.

Use a homebrew application like UMD Launcher or GPSP to launch the Windows 8 image on your PSP. You may need to configure some settings, such as the screen resolution and keyboard layout.
