I believe I may have discovered an issue relating to Windows 10 and the Sophos endpoint agent. I upgraded to Windows 10 yesterday and checked device manager to find that my DVD-RW was not functioning properly. If I uninstall the device, rescan for hardware changes and let it automatically reinstall, it functions properly again. Upon rebooting, the DVD-RW stops functioning again until I repeat the aforementioned steps. I have noticed that after rebooting, a second driver is added for the DVD-RW from Sophos: sdcfilter.sys. Presumably this is needed for the endpoint agent to perform device control functions such as blocking writable drivers which we do utilize in our environment. I'm not positive this is causing the issue, but that evidence suggests that. I am going to report this to Sophos support in hopes that it might be a bug that could be corrected in the upcoming 10.6 release for all those early adopters but I thought I'd post it on the forums as well in case anyone had a similar experience. I've attached two screenshots to support my post.
Hello All, my first post in the forum
just came here finding with google the problem explained by jbull, i have exactly the same problem happened two times so far, upgrading from 1607 to 1703 and again from 1703 to 1709, i thinked it was a windows related problem but the solution posted here to install manually sdcfilter.inf worked also for my notebook HP 250 G5
weird thing was it solved itself while using 1703, now it can be explained that a sophos update caused a new installation of it and so it made the dvd back working again as someone noticed
i hope it will be fixed with next releases but now we have a workaround for every major windows update
In reply to Simone Pecchenino:
It should now get re-instated on the first update of Sophos (data, or product) following the upgrade of the OS where it is not migrated.
This probably explains how it was fixed "while using 1703".
has been updated with a note I see.

I'll leave this message here, but will also forward it to my Sophos partner since I doubt anyone from corporate actually reads these forums.
I have removed Sophos AV from all of my Windows 10 computers. More Windows 10 computers are coming next month. They will not be receiving the Sophps product.
I will not be renewing my 100+ license subscription this summer and going with a solution that doesn't constantly prevent my users from getting work done. My DVD drives work just fine without the Sophos product installed, so I don't understand how you can blame Microsoft.

I get it! This took WAY too long for Sophos to fix. Ridiculous.
Here is what Sophos told me a few days ago, but I do not have any machines that need a build upgrade so I can't test it
Hi Sean, My Global escalations team has gotten back to me and we released version 10.7.6 for the anti-virus component which has the fix for the dvd drive issue. Just wondering if you are still seeing this issue and if you are we would need a new set of logs. To confirm what version you are running you could open Sophos on the endpoint, click on "about" in the bottom right hand corner, click on "Run diagnostic tool", then click on "installed components" and you should see for the anti-virus as 10.7.6.117

I just had my last Windows 10 machine have it's DVD drive disabled by Sophos ... under Central I see this:
Agent Update Status10.7.6 VE3.70.2 Update Successful
I hope you have better luck fighting this issue, I've given up.
