[tor-relays] How To Update The Tor Expert Bundle To Tor 0.3.4.9

Hello, So I am running an obfscated bridge on Windows 10 via the tor expert bundle, which, even when I tried downloading it today, is running tor 0.3.4.8. I was unaware that tor 0.3.4.9 had been released due to this. Do to being away from where the relay is running, I will not be able to update it for about 4 days, but how could I update the tor expert bundle to tor 0,3,4,9? How could I update the tor expert bundle to the newest tor in general?

Thank you.
