We've been running with KACE patching for our ~100 desktops for the past few months and have had problems with:

(1) PCs rebooting even though user did not authorise a reboot
(2) applications shutting down (e.g. MS Office apps) due to patch installs
(3) various and sundry usability complaints (e.g. user cannot defer install to set time of day or when shutting down)

As a result, I'm very nearly at the point of abandoning KACE patching altogether and returning to WSUS.  I've formed the opinion that the KACE patching mechanisms are buggy, unreliable and must have been designed from an IT admin-only perspective without taking into account the needs of the end user.

Is there any hope on the horizon?  e.g. might the next version of the Agent introduce much improved patching functionality, or would waiting be a futile exercise?

I hate to return to a product like Microsoft WSUS, but right now it seems to be clearly better than the KACE offering.
