+# Introduction
+
+Yet another Windows XP in the browser, but with a File System and comes with it, Programs.
+
+_Microsoft and Windows XP trademarks & logos definitely belong to Microsoft Corporation. All the programs' names and logos (Foxit, Word, WinRar, Internet Explorer, etc.) are of their rightful copyright holders._ _**win32.run**_ _is purely for the purpose of nostalgia. I have no intent and no right to monetize_ _**win32.run**__, but you may occasionally see ads when playing third-party games._
+
+win32.run runs purely on the client-side (the user's browser). All files are processed right in the user's browser. There is no file uploading, no server-side processing (cause I'm broke, can't afford it). Each user has his own OS session (just like the good old Windows XP)
+
+Files (and Folders) in win32.run are stored locally in IndexedDB. Apps (and 3rd-party apps) can interact with files through win32.run homemade file picker and saver dialog (with Windows XP appearance).
