/optimize:memory — RAM + Background Process Cleanup

Identifies what's consuming RAM at idle and reduces it by cleaning up startup items and setting unnecessary services to manual start.

---

Step 1 — Measure before

Run scripts/02_benchmark.ps1 -Label "pre" as Administrator.

---

Step 2 — Capture current state

Run scripts/01_diagnose.ps1 as Administrator.

Focus on:

• ram_info.json — total, free, used %
• processes.json — top processes by RAM
• services.json — running services with RAM
• startup_items.json — everything loading at boot

---

Step 3 — Ask about use case

Before making any changes, ask:

What software do you actively use on this machine? Focus on: audio interfaces, DAWs, game launchers, dev tools, remote access, backup tools, cloud sync, communication apps.

What do you need available immediately when the PC starts? vs. what can open when you actually use it?

This determines what stays in startup vs. what becomes manual.

---

Step 4 — Analyze and propose

Group what you find into three buckets and present it to the user:

KEEP in startup — essential to the user's stated workflow (e.g. Plex if running as a server, Parsec if used for remote access, audio interface notifiers, Defender/SecurityHealth)

REMOVE from startup — loads at boot but user launches manually anyway (e.g. Spotify, Discord, Epic Games Launcher, EA Desktop, Notion, Slack, backup tools that can sync periodically)

SET SERVICE TO MANUAL — service starts when needed, not always Present each with: what it does, RAM it's using, why it's safe to set to manual.

Services safe to disable outright (not just manual):

• DiagTrack — Windows telemetry, no user benefit
• SysMain (Superfetch) — irrelevant with SSD + 16GB+ RAM
• Xbox services (if not using Xbox features): XblAuthManager, XblGameSave, XboxGipSvc, XboxNetApiSvc, BcastDVRUserService
• RemoteRegistry — security risk, no use case for most users
• TabletInputService — only needed with touchscreen
• Fax — unless there's a fax machine

Wait for explicit approval on the list before making any changes.

Step 5 — Execute

Back up startup registry first:

reg export "HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Run" backup_hkcu_run.reg /y
reg export "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run" backup_hklm_run.reg /y

Remove approved startup items:

Remove-ItemProperty -Path "HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\Run" -Name "AppName"

Set approved services to Manual:

sc.exe config ServiceName start= demand
sc.exe stop  ServiceName

Set approved services to Disabled:

sc.exe config ServiceName start= disabled
sc.exe stop  ServiceName

Kill processes from removed startup items (so the change takes effect now without needing a reboot):

Stop-Process -Name "ProcessName" -Force -ErrorAction SilentlyContinue

---

Step 6 — Measure after

Run scripts/02_benchmark.ps1 -Label "post" — prints the delta automatically.

Note: the full RAM benefit shows after a clean reboot, since some processes that were already running stay in memory until then.
