Software management excels with comprehensive modules
We are a reseller. I am conducting some research since we are a vendor for the Kaseya solution.  Regarding the patching and software management, for me, it's the best path. We have all the necessary modules for monitoring on the server and workstations. All modules are working well, and for me,…
Mladen Vidic - PeerSpot reviewer
Has supported routine update requests and maintained reliable system operations
I think that the most valuable feature of Microsoft Windows Server Update Services is the update for Microsoft Windows Server, as we do not use any other tools, but I don't know if Office 365 is under Windows update services regulation; it is not in our domain because we use it, but other teams are responsible for this task. The key features or benefits of Microsoft Windows Server Update Services that have been most valuable in my IT administration processes are just the services for updating my Windows and Windows Servers, and as I mentioned, we don't use many applications; we just use it for Windows updates. Microsoft Windows Server Update Services supports our regular requests for reliable systems, and updates are part of the process of keeping those systems stable, reliable, and confidential.
