Session log: EVS Win11 context menu -> Win10-style revert

New clients/evs/ directory with session log documenting the
registry tweak to restore the classic right-click context menu
on Howard's EVS VM (reg add of empty InprocServer32 under the
Win11 new-menu CLSID, per-user HKCU, no admin needed).

+# 2026-04-17 — EVS Win11 right-click menu fix
+
+## User
+- **User:** Mike Swanson (mike)
+- **Machine:** DESKTOP-0O8A1RL
+- **Role:** admin
+
+## Summary
+
+Short ticket. Howard reported the Win11 VM at EVS (Equity Valuation Services) has the new compact right-click context menu, which confuses him. Provided the standard per-user registry tweak that reverts it to the Win10-style full menu.
+
+## Solution
+
+Per-user registry key. No admin elevation required. Run in PowerShell as the affected user on the VM:
+
+```powershell
+reg add "HKCU\Software\Classes\CLSID\{86ca1aa0-34aa-4e8b-a509-50c905bae2a2}\InprocServer32" /f /ve
+Stop-Process -Name explorer -Force
+```
+
+Creates an empty `InprocServer32` default value under the shell-extension CLSID, which tells Explorer to skip the compact menu layer. Killing Explorer restarts it so the change applies immediately (taskbar flashes, no reboot).
+
+### Revert to Win11 default
+
+```powershell
+reg delete "HKCU\Software\Classes\CLSID\{86ca1aa0-34aa-4e8b-a509-50c905bae2a2}" /f
+Stop-Process -Name explorer -Force
+```
+
+## Notes
+
+- HKCU-scoped -> affects only the user who runs it on that VM. If Howard has multiple profiles on the VM, run in each.
+- Persists across reboots and updates. Microsoft broke it once in 23H2 but has been stable since. Works on 22H2 / 23H2 / 24H2 / 25H2.
+- CLSID `{86ca1aa0-34aa-4e8b-a509-50c905bae2a2}` is the Win11 new-menu shell extension handler.
+
+## Pending
+
+- Howard to apply on the VM (awaiting confirmation).
+- If Howard uses more than one user profile on the EVS VM, repeat for each.
+
+## Client notes
+
+EVS = Equity Valuation Services. This is the first entry in `clients/evs/`. Howard maintains the VM. No other infra captured for EVS yet — add when encountered.
