Windows Defender + Controlled Access Folder

3

Uninstalled my 3rd party AV for the 1803 update. They tend to interfere when updating windows.

So decided to uninstall and try Windows Defender and activated the Controlled Access Folder feature that helps against ransomwares.

It seems cool but found annoying things, many own Microsoft executables get blocked. When software that is blocked is known to be safe, it’s a pain to add it to the allowed list. I thought Windows Defender would have been more intelligent on this side.

Would have been easy to ask in the notifications area to add a button to help add the software to the list.

Instead you have to drill down the event logs to find Windows Defender and find the blocked event. You have to do this since you don’t see the full path of the executable in the notifications area.

After seeing reviews from av-comparative.org and av-test.org. Seem that Windows Defender is starting to compete with other 3rd party AVs.

Microsoft just have to improve scanning performance and I think I would not install another one beside Windows Defender.

Just hope they add that button to help with applications needing protected folders access.

    I enabled Controlled Folder Access in January, and have been happy with it. Apart from a few niggles in the initial weeks, it's been very smooth sailing for me. It's also been interesting to see some apps that are attempting to perform writes in peculiar folders (e.g. the Steam client attempts a write in my Music library).


    Your point about being able to enable an app from the notification is very sensible - do file feedback to that effect, if you've not already done so.


    I have filed feedback asking for finer-grained control - today, you have a lost of controlled folders, and adding an app to the whitelist gives it access to all of them. I would prefer finer control over that - for example, my Steam games don't need access to anything but the Steam folder (and maybe a save games folder if its naughty enough to dump it in My Documents).

      I did send a feedback for enabling an app from notifications. I also use Steam, I had many games installed when I activated the folder protection. Took me some times for me to add launchers and games .exe to the list :)
