Important if you don't want to lose all characters on all Freelancer servers you were playing after reinstalling Windows or (sometimes) reinstalling Freelancer. Without a saved key they are impossible to recover. Here's a brief manual on how to save.
I. Simple way: Open myflaccountid.hta in Freelancer\EXE folder. There you'll see your account ID, save it to a separate text file or print.
When the game is launched 1st time after reinstall, the window will open up with a prompt to save newly generated key or input the old one. Simply input the old key you've saved into that window and you are done. As normal copy-paste won't work, you'll have to copy code manually, therefore it might be a good idea to print the it.
II. More complicated (regedit involved): First of all, launch "regedit" from command line.
Find HKEY_CURRENT_USER\Software\Microsoft\Microsoft Games\Freelancer\1.0
There will be InstallKey string where Freelancer key is stored, you may save it or change it directly in Regedit.
