It’s a notepad replacement, and I’ve been using it for years. One stitches it into Windows and it out-performs Notepad. I’ve inserted it into every copy of Windows I’ve used over the years, but it keeps getting harder to replace a “system file”.
The Metapad website has some instructions for inserting it into Windows 7, which work perfectly on a 32-bit (x86) OS. Trouble is, the 64-bit (x64) Windows 7 behaves a bit differently.
I’ve rewritten the instructions (originally provided by Brian Scott) to reflect what works on the x64 system. (I also emailed this to the author of the software, of course, but I figured I’d make it available right away in case others have this issue and need the code.

1. Rename the downloaded metapad.exe file to notepad.exe as usual, then copy it to Drive C (not inside a folder). Open an Elevated Command Prompt by clicking All Programs (in Start Menu) and Accessories, then right-click Command Prompt and click Run as administrator.
2. Copy the following and paste it into the Command Prompt box, where it should run automatically. Close the box when finished and delete C:\notepad.exe.
