Create a new empty branch in Git
$ git checkout --orphan NEWBRANCH
$ git rm -rf .

--orphan creates a new branch, but it starts without any commit. After running the above command you are on a new branch "NEWBRANCH", and the first commit you create from this state will start a new history without any ancestry.

You can then start adding files and commit them and they will live in their own branch. If you take a look at the log, you will see that it is isolated from the original log.

Portable Node.js and NPM on windows
  1. Get node binary (node.exe) from http://nodejs.org/download/
  2. Create the folder where node will reside and move node.exe to it
  3. Download the last zip version of npm from http://nodejs.org/dist/npm
  4. Unpack the zip inside the node folder
  5. Download the last tgz version of npm from http://nodejs.org/dist/npm
  6. Open the tgz file and unpack only the file bin/npm (without extension) directly on the node folder.
  7. Add the the node folder and the packages/bin folder to PATH
  8. On a command prompt execute npm install -g npm to update npm to the latest version

Now you can use npm and node from windows cmd or from bash shell like Git Bash of msysgit.
