If you need to rollback a Windows Update particularly if your MIDI system is no longer working, first confirm it is a MIDI 2.0 issue:
Go to Windows Tools → Services
Restart Windows MIDI Service (Stop → Start)
If ports return temporarily, it confirms the issue.
2️⃣ Create a Restore Point
Search Create a restore point
Click Create
Name it (e.g., Pre-MIDI Rollback)
3️⃣ Uninstall the Recent Update Only
Settings → Windows Update → Update History → Uninstall Updates
Remove the latest cumulative/feature update:
In the Start Menu look for Windows Settings / Windows Update and go to Update History
Scroll down until you see these three Updates. Uninstall all 3.

Restart Windows
⚠ Do NOT reset Windows — only uninstall the update.
4️⃣ Pause Windows Updates
Settings → Windows Update → Pause updates
This prevents automatic reinstallation.
5️⃣ Verify Stability
Open LoopMIDI
Launch DAW
Reboot once to confirm ports remain stable
