I dont understand your reply, so are you saying i should update via the Release Candidate channel? because this router is currently running the latest rOS, 6.37.3 the only newer release is a “beta” 6.38rc49.
Sorry for resurrecting an old post, but I’m running 6.40.3 on a RB750Gr3, and see the same issue - frequent DNS queries to upgrade.mikrotik.com (approximately a couple times every minute).
Has the bug on 6.33 early versions crept back into the code?

Like the previous posters, both cloud services are disabled.

Thanks for the quick reply - apologies for the slow follow-up. To answer your question, I did not have QuickSet open, but I did have many windows open in WinBox, and your reply gave me a hint.
I was able to replicate the problem tonight.
I first opened WinBox and setup my logging to show all “dns”.
I waited a few minutes then verified that there were no dns queries to upgrade.mikrotik.com
I then triggered a query by opening System->Packages, clicking on “Check for Updates” and then clicking in the popup window on the next “Check for Updates”.
This triggered the same pattern of queries (about a couple per minute) reported earlier.
I then closed both the “Check for Updates” and the “Package List” windows, but the DNS queries continued at the frequency of about a couple queries a minute - with all but the Log window closed.
I was able to stop the dns queries by closing WinBox and reopening it.
Is this a bug, or expected behaviour according to the way WinBox is coded?
Yes, the IP CLOUD features are off. I checked both locations you mention - and I also verified that System->Clock, Time Zone Autodetected is deselected.
As a test, I checked what would happen if I turned on one of the cloud features. If I turn DDNS on, then I see (as expected) additional DNS query’s to cloud.mikrotik.com.
In this example, the “item changed by admin” was turning on DNS.

Anyway - not to worry. Too bad you can’t reproduce, but I now know that if I close WinBox and reopen it, the queries to upgrade.mikrotik.com stop (until I force an update check in WinBox, at which point they continue until I close WinBox).
I just tried DaveN’s procedure and I have the same resutls.
I don’t use any Cloud features nor Timezone autodetect. It is triggered only by “Check for updates” button.
Also If I flush the DNS cache (and keep flushing it) then the queries are done every 10 seconds.
Otherwise every X minutes (where X is the TTL of the DNS replies).
Restarting winbox makes these lookups to stop and all cached DNS replies related to upgrade.mikrotik.com expire (otherwise they are keep getting refreshed since they are being looked up periodically).
Also this is not consistent. After restarting windbox and trying to flush the DNS cache again it didn’t try to lookup every 10 seconds as it did the first time I tried it. But it will definitely keep trying at other intervals until winbox is restarted.
