If you already read this forum vote in the polls, if it worked or didn't work.
Note: This setup is completely harmless, so nothing will happen to your PSP.
1. Download this file:

Then save it. (It'll be easier to save it on your Desktop).
(If you have WinRAR it will come up as a WinRAR file, otherwise it will just come up as a original Window.)
Want WinRAR?


2. Unzip or open the file and then you will see a ReadME file and a folder called win. The win file is what we're
intrested in.
(The ReadMe file is a sort of instruction booklet).
3. Connect your PSP the Computer or Laptop using your USB Cable. Put your PSP in USB Mode. Open up your PSP files (Removable Disk [E:]).
(The PSP file Window and the Window with the win file and the ReadME file both must be open).
4. Drag the win file then drop it in the PSP file Window or you could just copy and paste it.
5. Disconnect your PSP then go to the Internet Browser (you may need or not need an internet connection), then in the Address Bar type in:
file:/win/index.html
(Once you get on you may want to Bookmark this)
ENJOY!

If you want older or latest versions of Windows on your PSP then please post a reply.
I also know how to put flash GAMES on the PSP. (Requires a Computer or Laptop).
