why not unload driver

NTFSD
1

Hi,

I’ve read in several places that it isn’t a good idea (except for
development/debugging) to unload a FSD. Unloading and then loading a
newer driver would be quite useful for upgrades because rebooting would be
avoided. What are the pitfalls to unloading drivers?

Thanks,

Steve

There are APIs used by file systems that do not properly support unloading.
For development, if you wish to take the risk of crashing after an unload,
that’s fine. But it isn’t reliable enough to ship a product.

FS filters cannot be unloaded. Period.
FSDs possibly can, but only after dismount of all volumes.
