I have registered on Windows Insider program and right now I am slow ring. Yesterday I updated my Lumia 640 which is on build 10586.29 . Is this the latest build available for slow ring. What if i wanted to switch to fast ring and try the newer build. Please suggest.

Thanks in advance

10586.36 is the current version for slow ring.
The latest fast ring .63 has only performance and stability improvements, so it probably doesn't matter too much which build you try at the moment.
Read Windows 10 Mobile Insider build 10586.63 is now available (for some) on Fast Ring | Windows Central for more info.

Thank you :)
So can I switch to fast ring from slow ring.. It is possible as currently I am into the slow ring?

Go into the Windows Insider app and choose fast ring, it'll probably force a reboot of your phone.
Then check for updates for .63 build.

I did exactly that. I was on slow ring but wanted this .63 version. Just change I windows insider app and restart phone.
