⚡ Windows RAM Optimizer — 1.6GB Idle RAM for 8GB PCs

4304MB → 1569MB on Windows 11 26200 (8GB). ReviOS-grade, one-click, permanent.

Tired of 3GB+ idle on 8GB? This turns your 8GB Windows 11 into a ~1.6GB idle machine — game-ready, without breaking daily use. Live-tuned from a real 3.2GB leak (taskhostw 1.4GB, MemoryCompression off, ReviOS task broken 9/6) back to 1.56GB TaskMgr.

🆕 v2 — pure-PowerShell edition (ramfix.ps1) — now the recommended path

No Node / npm / Python required — one script, runs on any stock Windows 11.

• 🎨 Graphics-safe watchdog — never trims DWM / shell / visible / foreground / GPU-active / critical-system processes, and never purges standby memory while you drag (single or multi-window) or when the GPU is in 3D → dragging stays smooth, no "graphic loss"
• 🎮 Genshin-ready — GenshinImpact, NZXT CAM and cam_helper are force-trimmed every 2-minute cycle, page file pinned to 16GB (commit limit 14 → 24GB)
• 📉 -Mode Reduce — deep process cut: svchost 50 → 27, session-0 66 → 40, OS baseline ~76 processes
• 🖥️ NZXT CAM 50MB overlay — starts with Windows, opens no terminal window (the stuck-Windows-Terminal bug is fixed), ~60–120MB resident
• 🛡️ Survives Windows Update — self-heal re-applies anything an update resets and writes a repair: line to the log
• 🐝 Bluetooth untouched, memory compression left ON, fully reversible (-Mode Revert)

🚀 Quick start — PowerShell edition (recommended)

Download or clone, open PowerShell as Administrator in the folder:

Set-ExecutionPolicy -Scope Process Bypass -Force
.\ramfix.ps1 -Mode Apply        # base profile (UAC prompt)
.\ramfix.ps1 -Mode Reduce       # deep process reduction -> ~76 procs + self-heal armed
.\ramfix.ps1 -Mode CamSetup     # optional: NZXT CAM 50MB overlay (only if you use CAM)

Modes

Mode	What it does
-Mode Apply	Base profile: memory compression ON, RAM watchdog task, Defender exclusion, HKLM Run, fixed 16GB page file on C:
-Mode Reduce	Deep cut: ~15 services → Disabled, ~25 → Manual, per-user templates demand-start, Edge/OneDrive/Widgets autostart removed, svchost split threshold 16MB, writes targets.json and arms self-heal
-Mode CamSetup	NZXT CAM → overlay-only: mini HUD on startup, hardware acceleration off, CAMService Automatic, logon starts the exe directly (no console), silent desktop shortcut
-Mode Status	Live RAM / MMAgent / scheduled tasks / watchdog log
-Mode PurgeNow	One purge right now (drag guard bypassed on purpose)
-Mode Repair	Run the self-heal sweep now (it also runs automatically once per boot)
-Mode Revert	Undo everything: services, telemetry, task, exclusions, page file, CAM settings, autostart entries
-Mode Apply -Aggressive	Also cuts Spooler / BT / Maps etc. — not recommended (Bluetooth is kept by default)

Verify

.\ramfix.ps1 -Mode Status      # RAM, MMAgent, task state, watchdog log tail
Get-Content C:\ProgramData\ReviOS\watchdog.log -Tail 20

Log lines you should see every 2 minutes:

2026-10-12 15:38:12  game-trim cam_helper(9188) 11MB; NZXT CAM(6384) 58MB; ...
2026-10-12 15:38:14  trim=26 kept=45 PURGED status=0x00000000 free=5240MB admin=True
2026-10-12 16:00:13  repair: PageCombining on        # self-heal fixed something an update reset

🛡️ Why dragging never loses graphics

The stock EmptyStandby.ps1 trims every process and purges standby memory blindly — that is exactly what makes dragging a window (or several) stutter and "lose graphics" on an iGPU that shares system RAM. The v2 watchdog (ps/EmptyStandby.ps1) adds guards on every 2-minute cycle:

• Never trimmed: dwm.exe, csrss.exe, explorer.exe, sihost.exe, ShellExperienceHost, SearchUI, the foreground process, any process with a visible window, any process using the GPU, and critical system processes
• Only trimmed: processes that are CPU-idle right now (GetProcessIoCounters deltas)
• Purge skipped when: a mouse button is down (drag in progress), the cursor moved in the last ~1.3s, or a 3D/video GPU workload is running
• The purge uses the correct privilege (SeProfileSingleProcessPrivilege) instead of failing silently with 0xC0000022

DragFullWindows stays at 1 — Aero drag is never disabled.

🛡️ Survives Windows Update

Windows Update (and app updaters) quietly reset service start modes, re-add startup entries, flip MMAgent off and can drop scheduled tasks. v2 writes the desired state to C:\ProgramData\ReviOS\targets.json and re-applies it:

• ReviOS-LogonRepair — SYSTEM scheduled task at every logon (session 0, never shows a window)
• the watchdog — calls the repair in-process on its first cycle after each boot, so even a broken/missing logon task gets fixed
• Each task re-registers the other if an update removes one
• Every repair is logged: look for repair: lines in watchdog.log
• -Mode Repair runs the sweep immediately

Repairs cover: service start modes, per-user service templates, policy keys (Widgets, telemetry, activity feed), svchost split threshold, page file size, memory compression, Defender exclusion, HKLM Run entry, and Edge/OneDrive/NZXT autostart cleanup.

🖥️ NZXT CAM — 50MB overlay that starts with Windows

-Mode CamSetup (run once after installing NZXT CAM):

• Settings: miniModeOnStartup, startMinimized, startCAMMinimized, disableHardwareAcceleration (snapshots backed up, fully revertible)
• Logon entry runs "C:\Program Files\NZXT CAM\NZXT CAM.exe" --disable-gpu --disable-hardware-acceleration --in-process-gpu --startup — no console process at all
• CAMService stays Automatic so sensors are up before the HUD
• The watchdog force-trims CAM every cycle → ~60–120MB resident with a 318×67 HUD, vs the full app
• Desktop shortcut CAM Overlay 50MB.lnk starts it silently

Bug fixed in v2: the old logon entry started powershell.exe, CAM inherited that console and cam_helper kept it alive — so a Windows Terminal window sat open at every logon forever. Also -WindowStyle Hidden is ignored because Windows Terminal is the default terminal; the shortcut now goes through a hidden wscript launcher, and CAM-Overlay.ps1 starts CAM with CreateNoWindow.

📉 What -Mode Reduce cuts

Action	Effect
~15 services → Disabled	diagnostics/telemetry/discovery: DPS, PcaSvc, DoSvc, DusmSvc, lfsvc, SensorService, SSDPSRV, NcbService, TrkWks, iphlpsvc, lmhosts, ...
~25 services → Manual	Spooler, ClickToRunSvc, WSearch, Intel/Realtek helpers, LanmanServer, wlidsvc, TokenBroker, ClipSVC, ...
Per-user templates → demand-start (Start=3)	WpnUserService, CDPUserSvc, NPSMSvc, CloudBackupRestoreSvc
Startup cleanup	Edge / OneDrive autostart removed, Widgets policy off, per-user .lnk.bak boot popups moved to C:\ProgramData\ReviOS\StartupBackup
svchost grouping	SvcHostSplitThresholdInKB = 16777216 → svchost 50 → 27 processes

Bluetooth services (bthserv, BTAGService, BthAvctpSvc) are not touched — Bluetooth keeps working.

♻️ Revert

.\ramfix.ps1 -Mode Revert     # PowerShell edition: everything back (services, telemetry,
                              # task, exclusions, page file, CAM settings, autostart)

Node edition: ramfix --revert.

📦 Node / npx / Python editions (v1 — still supported)

The original one-click app. Recommended only if you already have Node/Python; the PowerShell edition above does the same job with more safety and zero dependencies.

GUI App

npx windows-ram-optimizer --gui
# or
npm i -g windows-ram-optimizer
ramfix --gui        # same as win-ram-optimizer

Opens http://localhost:8787 → Fix now — 1.6GB idle (admin). Run GUI/terminal as Administrator (right-click → Run as admin).

CLI

ramfix                 # safe profile
ramfix --aggressive    # also Manual Spooler/BT/Maps
ramfix --status        # RAM / MMA / task
ramfix --revert        # restore WSearch/SysMain

Python (Tkinter)

python python/optimizer.py --gui
python python/optimizer.py

📊 What the v1 editions do

Area	Action	Saved
RAM watchdog	C:\ProgramData\ReviOS\EmptyStandby.ps1 Boot + every 2min indefinite (ReviOS-EmptyStandby task) — EmptyWorkingSet + NtSetSystemInformation 80 + GC	~1.2GB
Memory compression	Enable-MMAgent -MemoryCompression/-PageCombining + HKLM\Run ReviOS_FixMMAgent	~700MB
Services	DSAService/DSAUpdateService/WSearch/CAMService/postgresql-x64-18 → Manual, AsusUpdateCheck → Disabled	~400MB
Telemetry	DiagTrack/dmwappushservice Disabled, AllowTelemetry 0, EnableActivityFeed 0	privacy
CAM 50MB	Kill NZXT CAM.exe UI, keep CAMService (10MB) + cam_helper; CAM-Overlay.ps1 --disable-gpu + trim; block HKCU Run NZXT.CAM	650→50MB
Pools	SystemCacheLimit 1GB, Defender exclusion	stability

🗂️ Layout (PowerShell edition)

File	Role
ramfix.ps1	Entry point — all modes, UAC elevation, baselines + revert
ps/EmptyStandby.ps1	Guarded watchdog (trim + purge + drag guard + game-trim + self-heal call)
ps/Repair.ps1	Self-heal from targets.json (runs at logon as SYSTEM + once per boot)
ps/CAM-Overlay.ps1	Overlay-only CAM launcher (starts CAM detached from any console)
ps/FixMMAgent.ps1	Keep memory compression + page combining on after boot
tools/probe-purge.ps1	Diagnostics: verify the purge privilege and NtSetSystemInformation result

Everything deploys to C:\ProgramData\ReviOS (with a Defender exclusion) so it survives reboot and Disk Cleanup.
