I've no idea what you mean. I installed Windows 10 in October on both my MBPs and have updated through every subsequent build. Both are currently on build 10049.
If your question really is "how did you find Windows update" the answer is easy. Press on the windows key (the cmd key on OSX keyboard) and then type "Windows Update".
Pressing the cmd key in windows is like pressing cmd+space in OSX - it brings up the search and you can then type in what you are looking for.
