Like the title says I can't move files fo system folders on a fresh win 10 install, sometimes it displays nothing other times it displays an access denied popup.
It only happens with dopus explorer is ok can you please tell me how to disable this ?
It sounds like your system's UAC settings are messed up. If UAC is disabled, Explorer would not be asking for permissions. And it seems like Opus can ask when you click the Admin Mode button but not while doing a file copy, if I understand correctly?
I would check the UAC control panel, and also the group policy settings (if you have edited those in the past) to see if they are still how you want them.
Turning UAC on/off, rebooting, and then back to how you want it again, and rebooting again, may reset things.
(Do you mean UAC is fully disabled, or just that it's set to one of the values that doesn't prompt as often in Explorer, for example?)
In Windows 10, UAC can only be disabled via group policy settings, so that combination of questions tells me UAC isn't disabled. You may just have set UAC to never prompt you, which is different.
Try setting it to Always Notify so you can see what's going on a bit easier.
If you still get an access denied error when copying certain files to certain places, it may indicate the files are in use, or permissions prevent even an admin account from doing the operation.
When you test in Explorer, are you doing exactly the same operation?
The options under Preferences / File Operations / Copy Attributes can also play a part. For example, if you have Opus set to update permissions when moving files, Explorer doesn't do that, and it's an extra thing which may fail (although it failing would not usually mean the move itself fails, it might with some of the other options there).
