Update
We are continuing to investigate the root cause of the Windows Update affecting peripherals on some PCs. This work will continue today however in the meantime we advise any customers affected to follow the steps provided to remove the update(s) and pause future updates for a short period.
To help with this activity, we have built a simple tool that you can run on any PC. It will search for the two updates, remove them, and offer you the option to pause updates.
You can download the tool here:

Monitoring
We have since Identified a workaround:
1. Go to Windows settings 2. Go to Windows updates 3. Go to update history 4. Scroll down to uninstall updates 5. Then, uninstall KB5066835 6. After this, if KB5065789 is showing as installed, then uninstall this too. 7. Restart PC.
Titan should then be working as expected, if you continue to have any remaining issues after completing these steps, please contact our helpdesk.
We recommend pausing your Windows updates for 2 weeks. We will continue to investigate this to ascertain the root cause and subsequent availability of a fix from Microsoft.
Thank you for your patience whilst we investigated this incident caused by a Windows update.

Identified
We are investigating an incident affecting PCs where they are unable to use peripherals with Titan.
This appears to relate to customers who have installed a windows update overnight. If no updates were installed then peripherals are working as normal.
We are working to identify the specific update causing this and will provide further information shortly.
