+# Introduction
+A very special exe I use for teaching Windows Internals. It's a version 2, somewhat improved, but I have never published v1 though.  
+It IS NOT harmful, you can use it on prod, but some AV/EDR may warn you it uses some suspicious techniques. It's true, as I try indeed to make it not too obvious. Matter of balance between looking good and being funny ;)  
+The tool IS NOT persistent. Reboot clears everything, leaving two or three innocent files on your C: volume.  
+NO ADMIN required. I want to play with you, and not destroy your computer...  
+The file is (obviously!) digitally signed.  
+
+# How to play:
+The exe creates "secret.txt" on your desktop, and the challenge is to read its content. Sounds simple, but it depends actually on your skills and knowledge. Try it: run the exe, read the file, enjoy!
+
+# The source code:
+I will publish the source code (~400LoC of C) in a couple of days. Publishing it right now would spoil the fun :P
