Tutorial How to slim Windows 10 and make it superfast

Today I will talk about the tools, scripts, and tweaks which will help you make your Windows 10 faster. Windows 10, in its nature, is already preconfigured to optimally run your everyday tasks with only resources it needs and it allocates, but in today's topic, I will try to explain what areas of the OS can be further improved for speed and still maintain its stability and security.

Tweaks for this theme were run and tested on Windows 10 Pro 64bit Version 1903 OS Build 18362.53 on Dell Vostro 1015, Intel Celeron Dual-Core 1.8GHz, 2GB Hynix DDR2 RAM and Silicon Power s55 240GB SSD, Intel iGPU with the resolution of 1366 x 768.

Before anything, be warned that you will be dealing with some core functionality of Windows, things may go wrong for you for multiple subjective and objective reasons, so I advise you to backup your important data on external location and eventually make system image backup in case you don't like the result or just prefer using the default or your own Windows tweaks and settings.

Let's dive in, shall we?

For this matter, you can use Windows built-in tools like Regedit, PowerShell, Group Policy Editor, which will be used anyway, but for the sake of the size of this thread, I will use some third party tools which will make our job easier. So, you will need :

  1. Mirinsoft Cleanmgr+ [ Can be downloaded using this link Mirinsoft - Good apps are as little apps as possible - Cleanmgr+ - Download Summary ]
  2. O&O AppBuster [ Can be downloaded using this link https://dl5.oo-software.com/files/ooappbuster/OOAPB.exe ] [OPTIONAL]
  3. O&O ShutUP10 [ Can be downloaded using this link https://dl5.oo-software.com/files/ooshutup10/OOSU10.exe ]
  4. Win10 Debloater Script [ Can be downloaded using this link https://codeload.github.com/Sycnex/Windows10Debloater/zip/master ]
  5. Uninstall Microsoft Edge Script [ Can be downloaded from WinAero site following this link Downloads / Other / Uninstall Edge browser for Windows 10 ]
  6. Windows Privacy Dashboard [ Beta is quite stable and can be downloaded using this link https://wpd.app/get/beta.zip ]
  7. Functional Windows 10 Built-in tools
GLOBAL NOTE: These tweaks are optimized for system lightness, stability and only if you don't use Microsoft Egde (non-Chromium), Cortana, OneDrive, Skype App, Touch features, Features for enabling location and device position and movement, Speach recognition system, nondomain network connections, inter-device communication, Windows Sandbox, Error reporting, and some others.

Fully update your Windows System using Windows Update built into the system settings and go to Store App and update all your preinstalled apps. Why is this important at first, you may ask? Upon execution of these scripts, you can encounter a situation where the app you are trying to uninstall is in the process of updating, so although you could uninstall it, the app may stay there as nothing happened. So, the order in which you will execute each tweak is very important. Don't forget to reboot the system after completing this step.

Launch WPD (Windows Privacy Dashboard) with Administrator privileges (Run as Admin). WPD is mainly a privacy-oriented app but it can be used to disable, in this case, unneeded services Microsoft use to collect Telemetry and see which apps communicate among each other and in what order. After the app is launched it will present you its main GUI.


Next, you click on Privacy button and it will lead you to the portion of the program which will let you customize your privacy in Windows. Settings you see in the next screenshots are optimized for disabling unnecessary services, which will release resources upon the next system reboot, and maintaining privacy. Note that some tweaks are not enabled as I use Bluetooth radios on my laptop and Mail and Calendar App, albeit you can disable a few more but it might break the Windows Notification subsystem. Freedom is yours, and here is mine :


Launch O&O ShutUp 10 tool with Administrator privileges. O&O ShutUp 10 is also a privacy-oriented tool, but we use it, in this case, to complement WPD, as some features O&O has which WPD hasn't and vice versa. ShutUp 10 is usually released with each Windows Feature Update so we expect a new version soon which will cover 1903 completely. Here are my settings :


When you close the program after applying all these tweaks it will ask you if you want to reboot the system. Please, do so.

OK. Among other tweaks, we have prevented some apps from reinstalling themselves as Windows usually does it so we can move on. It's time to uninstall Microsoft Apps from the machine completely. Why did I say machine? Windows Apps are stored in Program Files Folder and some other folders in the "Users" folder which is usually hidden. App data are stored there for each Windows user and the whole machine in global. O&O AppBuster can help you uninstall apps from a specific user, from all users, and from the machine globally. But there are some limitations.
First of all, not all Windows Apps can be removed from your system totally, as some depend on others. Like Paint 3D depends on Photos App and cannot be uninstalled (from the machine) when Photos App is running. O&O AppBuster is a very young app and I am sure that it will improve in the future to notify the user which app is holding back and cannot be uninstalled with a detailed error log. But using this app you can successfully uninstall almost every app from the current user and from all users. Only some apps can be uninstalled from the machine using this way.

So, we will use a PowerShell and Win10 Debloater Script to uninstall every app from the system completely. Note, that I've experimented with trying to delete every unwanted Windows App by deleting its parent folder(s) from outside of Windows (using Hiren's Boot Pe or Slitaz Linux Distro), and it works without breaking the system, but registry entries remain and you can hardly detect them all manually. So we will use this script to do the job.

This script will remove the bloatware from Windows 10 when using Remove-AppXPackage/Remove-AppXProvisionedPackage, and then delete specific registry keys that are were not removed beforehand. For best results, this script should be run before a user profile is configured, otherwise, you will likely see that apps that should have been removed will remain, and if they are removed you will find broken tiles on the start menu.

Please do not continue if you don't want these apps removed:
3DBuilder, Appconnector, Bing Finance, Bing News, Bing Sports, Bing Weather, Fresh Paint, Get started, Microsoft Office Hub, Microsoft Solitaire Collection, Microsoft Sticky Notes, OneNote, OneConnect, People, Skype for Desktop, Alarms, Camera, Maps, Phone, SoundRecorder, XboxApp, Zune Music, Zune Video, Windows communications apps, Minecraft, PowerBI, Network Speed Test, Phone, Messaging, Office Sway, OneConnect, Windows Feedback Hub, Bing Food And Drink, Bing Travel, Bing Health And Fitness, Windows Reading List, Twitter, Pandora, Flipboard, Shazam, CandyCrush, CandyCrushSoda, King apps, iHeartRadio, Netflix, DrawboardPDF, PicsArt-PhotoStudio, FarmVille 2 Country Escape, TuneInRadio, Asphalt8, NYT Crossword, CyberLink MediaSuite Essentials, Facebook, Royal Revolt 2, Caesars Slots Free Casino, March of Empires, Phototastic Collage, Autodesk SketchBook, Duolingo, EclipseManager, ActiproSoftware, BioEnrollment, Windows Feedback, Xbox Game CallableUI, Xbox Identity Provider, and ContactSupport.

After you have download the zip file from GitHub repository, please extract it to your C partition first depth. So the addressed folder called "Windows10Debloater-master" has the "C:\Windows10Debloater-master" path (without the quotes, of course).

You then open the PowerShell as Admin and enable its execution policy by entering
Set-ExecutionPolicy Unrestricted -Force

On the prompt, change to the directory where you extracted the files, in this case
cd C:\Windows10Debloater-master

Then run the GUI script (recommended) by entering the following command

The following program will be executed and this GUI presented


You will click on Remove All Bloatware button.

Next, you will wait for the script to finish removing the bloat.



Removing Microsoft Edge completely from the system. After you have downloaded "Uninstall Microsoft Edge", please extract the archive to your desired location. Note that after extraction "install_wim_tweak" program and "Uninstall Edge" command script must be in the same folder and location.

Execute Uninstall Edge script by right click and Run as Administrator. Wait for the script to finish and reboot your system. Empty icons of MS Edge may be there sitting on your Desktop and Taskbar after reboot. You can freely delete and unpin those.

Disabling unnecessary Windows services.
First of all, we'll need to open the Services Manager to configure Windows 10 services. You can open Services Manager using several ways as given following:

Press WIN+X keys together to show quick access menu and then select "Computer Management" option. It'll open a new window.
Now click on "Services and Applications -> Services" in left-side pane.
The Same thing can be done by clicking on "Computer -> Manage" in "This PC" ribbon toolbar.
You can also right-click on the "This PC" icon on Desktop and select "Manage" option.
Or press WIN+R keys together to launch RUN dialog box and type services.msc and press Enter. It'll directly open Services Manager.

The Status section shows whether a service is currently running in the background or not. Startup Type section tells you whether a service is set to automatically start with Windows or not.
We'll set some unnecessary services startup type to MANUAL so that they don't start automatically with Windows and thus don't consume system resources.

NOTE: Always set a service's startup type to MANUAL and never set it to DISABLED. We suggest this because if a service is set to MANUAL start and Windows needs the service, it'll be able to start the service and there will be no effect on OS functionality. But if a service is set to DISABLED and Windows requires that service, it'll not be able to start the service and you may face problems.

Following are some services which can be safely set to MANUAL/DISABLED:
  • Connected User Experiences and Telemetry (To turn off Telemetry and Data Collection)
  • Diagnostic Policy Service (Not recommended if you wish for Windows to automatically fix something like resetting the wireless card, troubleshooting, icon cashe resetting, etc.)
  • Diagnostic Tracking Service (To turn off Telemetry and Data Collection)
  • Distributed Link Tracking Client (If your computer is not connected to any network)
  • dmwappushsvc (To turn off Telemetry and Data Collection)
  • Downloaded Maps Manager (If you don't use Maps app)
  • IP Helper (If you don't use IPv6 connection)
  • Program Compatibility Assistant Service
  • Print Spooler (If you don't have a printer)
  • Remote Registry (You can set it to DISABLED for Security purposes)
  • Secondary Logon (If you are the only Windows User)
  • Security Center
  • TCP/IP NetBIOS Helper (If you are not in a workgroup network)
  • Touch Keyboard and Handwriting Panel Service (If you don't want to use touch keyboard and handwriting features)
  • Windows Defender Service (If you don't use Windows Defender program)
  • Windows Error Reporting Service
  • Windows Image Acquisition (WIA) (If you don't have a scanner)
  • Windows Search (If you don't use Windows Search feature frequently)
Apart from the above-mentioned services, You can also set a few other services startup type to MANUAL such as services installed by your graphics card driver (Intel, nVidia, AMD, etc), your sound card driver (Realtek, Creative, etc).

You may notice that some services are already disabled because of WPD and ShutUp 10 's work, but check it twice anyways. This is purely individual which services you don't need and you wish to disable so I will leave this to you.

STEP 7. (optional)
You can further improve the performance of your computer by disabling animation effects in Windows but this doesn't fall into the "Slimming Windows" bucket so we can move on. Optionally you can disable some unneeded Windows Features in Programs and Features like Windows Sandbox (if you don't use it), XPS services, Media Features like Windows Media Player...

Cleaning the mess left behind.
Cleanmgr+ is a great tool for one use. For now. Developer needs to do some GUI improvements in my honest opinion like some basic features to be able to select all the tasks, settings buttons to be more naturally accessible, etc. But, for what it does, it does it superbly. Just run it as an Administrator and you can freely select all the boxes in the main tab and "more" tab and click.


Don't click "CleanUp" before you read this.
Among other things it cleans, Cleanmgr+ removes all your backup installations of Windows Updates, Windows components and program installations which Windows may need in case some program behaves abnormally and it needs to reinstall it or degrade to the previous version. WinSxS folder is one of them. Windows 10 and Windows Server 2016 automatically reduce the size of the WinSxS folder by using methods similar to the ones described in this topic, in addition to internal processes, such as uninstalling and deleting packages with components that have been replaced by other components with newer versions. Previous versions of some components are kept on the system for a period of time, allowing you to rollback if necessary. After a period of time, these older components are automatically removed from the installation.

Deleting files from the WinSxS folder or deleting the entire WinSxS folder may severely damage your system so that your PC might not boot and make it impossible to update.

If you don't want to mess with update backups and WinSxS folder please uncheck Windows Update CleanUp and Windows Component Store in the selection menu.

Click to cleanup, wait for it to finish and reboot.


Thank you for reading. Stay safe and do your work faster than before.

Thanks @BoraMurdar for this thread, I have marked it in favorites.
Of course W10 has too many things, which may be interesting for companies, but for a normal user with an old machine as in my case is too bloated.

Before seeing this thread I have been able to vary the RAM from 40/ 45% to 22% / 27% and up to 30%. For me it's still an exaggeration.:eek:

This is one of the best guides I've found for debloating my Windows 10 Pro installs. Besides Shutup10 which has become a staple for me after clean installs, I've never heard of the other tools recommended in this article.

I'm more interested in debloating on a clean install of W10x64 Pro. For this task, Spiceworks Windows 10 Decrapifier can be integrated during intial setup before any accounts are created (OOBE):
Post install, especially for existing installations suffering from bloatware, malware, etc Tronscript seems popular.
My only hesitation with all this (especially scripts that aren't easy to reverse the changes on) is the risk of future updates breaking things and also being over aggressive accidentally disabling basic functionality (for example IMAP email client, VoIP, video conferencing, etc).

I also considered homebrew ISOs narrowing it down to MSMG Toolkit, Win Tookit & Winreducer (I wasn't impressed by Winreducer's geocities interface & incessant ad nags). I decided against chopping up W10 Pro however because of the lack of really decent guides to simplify the entire process, how time consuming it is (would take days to learn & setup) and mostly the likelyhood of future updates breaking things in a chopped install.

In the end, LTSC 2019 won me over as the best of the three options (LTSC, Debloat, Homebrew) and for those not constantly upgrading hardware in say a desktop PC (I don't game) or wanting constant Windows Updates (no thanks, besides critical security updates) LTSC by far in my experience is the better option (and true sucessor to Windows 7 x64 Ultimate), especially for those with limited hardware resources (in my case 4GB RAM/32GB eMMC soldered onto motherboard).

Lastly, if not for those stuck on M$ say because of Office or Adobe products, Linux Mint Cinnamon runs like a dream for me with everything I need out of the box... Honestly, Windows 10 is the end of the line for me, especially now how the technocrats and neoliberals at M$ are moving full speed ahead towards their Windows as a Service... Microsoft aspires to be the world leader as a slavery cloud rental & planned obsolescence devices company.

Again, thanks for sharing!

How to clean up a single Windows 10 machine/image using Decrapifier
Thanks for this, will try for sure.

bmrf/tron & r/TronScript
Every single time I tried (maybe 4-5 times) to download the tools it had some server errors and I just couldn't complete the task.

LTSC is by far the most stable and lightest Windows, but home users are not interested in it. So, it's still a rarity, in legal waters.

Linux is being better with every release but some drivers are troubling me. It's a subjective problem with Broadcom and my affinity with DAW software and obssesion with media player funcionality that glued me to Windows.
Maybe it will change in the future.

Also, Microsoft needs scan upon execution option in Windows Defender ASAP. It's a simple implementation but can hugely improve overall Windows performance and responsiveness.

With all respect, please leave Windows alone. One does all types of tweaks and plays with "core" features and then complains a month later that the new windows upgrade failed for some reason, really?! I never tweaked Windows that much and it is running smooth and fast.
Try and explain that to Paranoid users who strongly believe Microsoft is reading all their private user data when they see the word Telemetry, and from reading others' scare mongering posts into believing companies are all spying on their users.

yeah, it's not really for normal users. However, after applying these tweaks and some other tweaks not mentioned here, Windows can be twice as fast according to my experience with many PCs
our PC is fast but the tweaks simply makes it a lot faster
I don't have any problem with windows but the only thing causing problems is when I use NTlite to trim down windows ISO -> failed to update, unfixable

Indeed, the best way is to check the number of Threads/Handles, the less, the better, obviously. I also like everything (CPU/Disk/RAM/Network) being calm at idle, no unnecessary activity, it is easy to find out then, if something does not belong, like malware, or just something causing issues.

a month later that the new windows upgrade failed for some reason,

It's great to be able to successfully apply a lot of these tweaks, but it doesn't always pan out. I'd removed Edge.html with the Winaero tweak in this guide and today, I could not get KB4512508 installed, not even via the Update Catalog,. So I had to run a repair-install of Windows. This KB has some Edge-specific changes, and if Edge isn't there, well: Fail.

So yeah. Tweak at your own risk cuz v. 1903 is an unpredictable beast.

Hi... thanks for the guide!

A win10 update just came out and the programs you mention above to use have gotten updated with new options and features. Could you do a updated guide to account for all these changes. I am trying to redo this guide and there is alot that is different so I'am confused and don't want to cause problems.

Thanks again!!!
