Unable to browse Macrium backup

I am running Win10/64 Home Ver. 1903 Build 18362.145 with no problems. I just discovered Macrium Reflect Ver. 7.2.4228 will not allow me to browse my backup files. I get all the proper dialogs, but when I click the C: image to browse nothing happens other than a 5 sec. window that shows the details of the backup file and then disappears.

I've used the Browse function many times before - in fact it is one of the key features I often use. But now it has stopped working. Nothing I've found by Google shows this problem so I'm wondering if there is something broken with my system. If so - how to find out what it is?

[QUOTE=dalchina;1646823]What do you see if you rt click an image file? Do you see an 'Explore Image' option?

Yes. Clicking Retore Image brings up the standard Macrium dialog/ Clicking C: results in no action.

Have you tried-
- reinstalling MR

yes - no help there.

Saw that one - doesn't seem to be a problem.

I installed Aomei Backupper and made a full backup which completed OK. I tried their Browse function - it failed with Information Code 4125, This says to reinistall the software.

I'm thinking something got wacked in latest Win10 update.

Sure can - I've got a number of DVD ISO's and they all mount fine.

Problem found!

Turning off Windows Defender Real Time Protection allows the backup file to be mounted.

So how do I flag this as a problem with the latest Windows update?

Edit: more weirdness - now that I mounted the backup file there is no way to eject/close/unmount it.

Edit2: rebooting got rid of it

Yes, the unmount option was not there when I right clicked on the mounted drive.
