Does anyone know how to remove a software update on the Sony Xperia Z tablet?

I received an update to Android Jelly Bean 4.3 today and really don't like the new interface. I think I had 4.2.2 before and want that back.

Can anyone help?

I'd like to know how / if too!
I think that this version is a bit unstable. My tablet now sometimes hangs when powering down.
KitKat is supposed to be coming in February and I suspect that we will have to wait for this though they will be tweaking the interface yet again.

Mine hangs when powering off as well,also sometimes the keyboard flashes when typing.Fix it Sony,I had no problems before the update.

We are not alone!

Ditto with the powering off issues. I have mine in a case with magnets that turn the screen off and I sometimes find that closing the case forces it to finally turn off but not always.

Officially you can't. You'd need to root the device and install a custom ROM (at your own risk and you'd void the warranty)
