Lutimize Screen-by-Screen Guide

Click the seven tabs below to see what each screen does and how to use it, complete with screenshots. Even first-time users can follow along with ease.

This is the first screen you see when you launch Lutimize

Your PC's Status at a Glance

CPU, memory, disk, and GPU information are all organized on a single screen. Color cues tell you at a glance how healthy your PC is, so you can immediately decide whether it needs cleaning or optimizing right now.

What This Screen Shows

CPU & Memory Usage

Shows in real time how busy your PC is right now.

Free Disk Space

The remaining capacity of each drive is shown at a glance with bar graphs.

Graphics Card Info

Check the model and status of the installed GPU.

Total Space Reclaimed

Shows the total disk space you've reclaimed by cleaning with Lutimize so far.

Total Optimizations Run

Shows a count of how many times you've run an optimization so far.

PC Health Status

Intuitively shows green (good) / orange (caution) / red (needs optimization).

Recommended For "I have no idea what state my PC is in right now" — just looking at this screen tells you whether it needs cleaning or optimizing.

Check only the items you want, then press the "Start Cleanup" button at the bottom

Clear Out Useless Space-Hogging Files in One Go

It clears out files that pile up in places you never see — browser caches, game launcher temp files, logs left behind by Windows, and more — all at once. It never touches your important documents or photos, so you can rest assured.

Items Cleaned (47 in total)

Browser Cache

Temporary files piled up in Chrome, Edge, Firefox, and more

Game Launcher Cache

Steam, Epic, Battle.net, Riot, Nexon, STOVE, and more

Windows Temporary Files

Update cache, Recycle Bin, system logs, thumbnails

Discord & Minecraft

Caches for frequently used programs are categorized separately, too

Duplicate File Finder

Automatically finds the same file saved across multiple folders

Previous Windows Folder

Windows.old left behind after a Windows update (can free up several GB)

How to Use

Check the Items You Want All items are selected by default. If there's anything you don't want cleaned, just uncheck it.
Click the "Start Cleanup" Button Press the large blue button at the bottom and cleanup starts automatically in the background.
Check the Results When it finishes, you'll see how much space was reclaimed this time, and it's automatically added to the "Total Space Reclaimed" on the dashboard.

It's Safe Every file cleaned here is just temporary data that Windows will regenerate. User files such as photos, documents, and game saves are never deleted.

Just click the trash icon to the right of the app you want to remove, and it's deleted right away

Cleanly Remove Rarely Used Default Apps & Bloatware

You can review and remove rarely used apps — preinstalled by Windows or bundled by your PC maker — all from a single screen. Since the list is gathered automatically, you can clean them up with a single click without digging through the Control Panel one by one.

What This Screen Shows

Auto-Collected Installed Apps

Automatically finds Windows default apps and programs installed on your PC and lists them with their real icons.

Publisher & Built-in Badge

Shows each app's publisher and version, and built-in Windows apps carry a badge so you can tell them apart at a glance.

One-Click Removal

Click the red trash icon to the right of an app once and removal begins.

Safe Removal Method

For apps that can't be removed silently, it launches the standard uninstall wizard to delete them safely.

Lutimize Self-Protection

The removal button is protected in the list so you don't accidentally delete Lutimize itself.

One at a Time

During a removal, other removal requests are locked out so they don't overlap, ensuring stable processing.

How to Use

Find Apps to Remove Look through the list for default apps or manufacturer-bundled apps you rarely use. It's best to start with apps whose name or publisher is unfamiliar.
Click the Trash Icon Press the red trash icon to the right of the app to start removal. Apps are processed one at a time.
(If Needed) Proceed Through the Uninstall Wizard For apps that don't support automatic removal, the standard uninstall window appears. Just follow the prompts.

Not Sure Which Apps to Delete? Start with apps you've never run or whose publisher (manufacturer) is unfamiliar. For apps you're unsure about, we recommend searching the name before deleting them.

Double-Check Before Removing Unlike toggle settings, undoing an app removal requires reinstalling that app. Please confirm you really don't need the app before proceeding.

View and manage the programs that launch automatically when your PC boots, all at a glance

Slow to Boot? — Clean Up Your Startup Apps

The programs that launch automatically every time Windows starts are the biggest culprit eating up your boot speed. Lutimize finds all registered startup apps and gathers them on one screen, letting you turn off just the unnecessary ones with a single toggle.

What This Screen Shows

Total Startup Apps

Tells you the total number of programs registered to run at boot.

Enabled Programs

Check at a glance how many startup apps are currently turned on.

Disabled Programs

The number of currently disabled startup apps is shown as well.

Startup Impact

Shows how much each program burdens boot speed, classified as Low/Medium/High.

Toggle On/Off with One Tap

Just press the switch on the right and it applies instantly. The program itself is not deleted.

Startup Delay

Delays the launch of all startup apps by N seconds to reduce the load right after boot.

How to Use

Find Unnecessary Programs in the List Turning off programs with Medium / High impact that you rarely use gives the biggest effect.
Disable with the Toggle on the Right Press the switch and it applies immediately. The program isn't deleted — only "auto-start" is turned off, so you can turn it back on anytime.
(Optional) Configure Startup Delay Enter a value in seconds in "Startup Delay" at the bottom, and the enabled startup apps will launch that much later after boot, spreading out the initial load.

It's Safe Only "auto-start" is turned off; the program itself stays installed. You can launch it manually whenever you need it.

Recommended For "I have to wait ages after powering on before my PC is usable" — cutting just a few startup apps makes a big difference in perceived speed after boot.

Lutimize performance optimization screen

Select the optimization items you want, then press the "Start Optimization" button

Boost Game FPS, Boot Speed & Internet Responsiveness

It adjusts even the deep settings Windows usually leaves untouched, all at once, to make your PC run faster. You'll notice less stutter while gaming, shorter boot times, and snappier internet responses.

Key optimization items (45 total)

Game Mode & Visual Effects

Prioritizes system resources while gaming and removes unnecessary animations

Network, NIC & DNS

Applies settings that lower internet response time and game ping all at once

High-Performance Power Plan

Changes settings so the CPU always runs at maximum performance

Memory & Disk

Optimizes memory management and disk write caching

Disable Telemetry

Blocks data that Microsoft collects in the background

Premium-Only Options

Extra items like disabling location tracking + batch optimization in about 5 seconds

Risk levels & applied status

Each item shows a risk badge (Safe / Caution / Danger) alongside its applied status (applied / not applied). The "Enable All (except Danger)" button turns on every item except Danger-tier ones in one click.

Restore defaults (undo)

Reverts applied optimizations to Windows defaults. "Restore Defaults" only reverts items whose toggle is on, so leave an item toggled on if you want it reverted. To revert just the Danger-tier items (GPU-level tweaks and the like) in one go, use the "Revert Danger Items" button — it works regardless of toggle state. Power options are restored to Balanced (the Windows default), and a system restore point is created before optimization starts.

How to Use

Select Optimization Items Use the "Enable All (except Danger)" button to turn on all Safe and Caution items at once, or use the toggle-all button and per-item toggles to pick exactly what you want.
Click the "Start Optimization" Button System settings are changed automatically. Progress is shown in real time.
Restart Recommended Some items take full effect only after a reboot. Please restart once if you can.

The Premium Plan Difference The Basic plan takes about 90 seconds, but the Premium plan optimizes every item in about 5 seconds. It also lets you fine-tune 6 additional parameters.

Press the ON/OFF toggles to change Windows settings quickly

Windows' Hidden Settings, All in One Place

Hard-to-find Windows settings like disabling Cortana, turning off IPv6, and removing mouse acceleration can all be switched ON/OFF with a single toggle. Advanced features like maximum monitor refresh rate and per-game CPU/GPU profiles live here too.

Key Settings

Disable Cortana

Completely turns off the unused voice assistant to reduce background load

Disable IPv6

A setting that reduces ping spikes in some games

Disable Mouse Acceleration

Essential for maintaining consistent aim in FPS games

Max Refresh Rate

Raises your monitor to its highest supported refresh rate (e.g. 60→144Hz). If you don't confirm within 15 seconds, it reverts automatically.

Game Profiles (CPU & GPU)

Assigns high CPU priority and the high-performance GPU to the games you choose, boosting in-game performance.

Show File Extensions

Always shows file extensions (.exe, .pdf, etc.) for all files in File Explorer

How to Use

Find the Item You Want Scroll through and find the setting you want to turn ON/OFF.
Change Instantly with a Toggle Click It applies the moment you press the switch. Press again to restore the original setting.
Settings Persist The settings you change persist even after you reboot your PC.

You Can Undo Anytime Every setting can be turned on and off with a single toggle. If you don't like it after trying, just switch it back right away.

Automatically diagnose every area of your PC with a single "Start Check" button

Automatically Check Whether Your PC Has Problems

It automatically checks whether Windows internal settings are misconfigured, whether abnormal processes are running, and whether there are any RAM or GPU compatibility issues. If a problem is found, it also attempts to repair it automatically.

Check Items

Registry Integrity

Checks for traces of changes made by malware

Abnormal Processes

Detects processes with suspicious names or odd locations

RAM & GPU Compatibility

Pre-checks for hardware conflicts before applying optimizations, and flags RAM installed in single channel

Laptop Environment Check

Checks laptop-specific items such as battery mode and power-saving settings

Auto Repair

If a problem is found, safe items are repaired automatically right away

Detailed Report

Clearly organizes the items found and how they were handled

How to Use

Click the "Start Check" Button Just press the button with no other configuration, and a full check starts automatically.
Check the Results A ✓ (normal) / ⚠ (caution) / ✗ (problem) mark appears next to each item.
Auto Repair Runs Items where a problem is found are repaired automatically within a safe range.

When Should I Use It? It's best to run it once before applying optimizations, and then regularly about once a month.

Frequently Asked Questions

Do I really have to grant administrator privileges?

Yes. Since cleaning and optimizing require access to system areas, you'll need to click "Yes" in the UAC (User Account Control) window the first time you run it. Once you allow it, it's handled automatically from then on.

Could my photos or documents be deleted?

No. The only areas Lutimize cleans are temporary files and caches that Windows regenerates. It never touches your documents, photos, Downloads folder, game save files, or the like.

What if my PC acts strange after optimization?

The toggles on the Preferences tab can be turned back off anytime, and most performance optimization items operate only within a safe range. If you're still concerned, we recommend creating a Windows System Restore point before applying.

How often should I use it?

File Cleanup once a week, Performance Optimization after a major Windows update or whenever your PC feels slow, and System Check about once a month is a good rhythm.

My antivirus shows a warning when I run it. Is it okay?

Because Lutimize works with deep system areas, some antivirus programs may temporarily show a warning. The file is signed with a valid digital certificate and is safe. You can add Lutimize to your antivirus's exception list, or for a SmartScreen warning, click "More info → Run anyway" to proceed.

What is Lutimize Pass?

Lutimize Pass is a time-based add-on for Basic/Premium plan users (30 or 365 days). It is not a subscription — while active, you get Lutimize Lite, the Pass-exclusive lightweight client (scheduled optimization and cleanup, background memory optimization, plus result reports emailed to you), can register up to 3 devices, use every milestone badge, and get exclusive nickname colors (red/purple) plus a PASS badge. When it expires, it simply ends and your account returns to 1 device.

Get Started Right Now

Download Lutimize and just follow the guide above once. You'll feel a clear difference in the speed of a PC that used to frustrate you.
