This guide explains step by step how to remove Windows Compatibility Settings on Steam, the Steam Overlay and the Steam Service that don’t appear in the properties window of the .exe files. Windows often applies settings without any warning or permission, which means that Steam will typically run slower, freeze or hang. This issue is made worse because Steam only sometimes warns for settings applied to Steam but never the Steam Overlay or Steam Service.

You might find that this fix helps prevent freezing or that Steam runs faster even if no messages have appeared and you’re not having any issues, because Steam should never be run in compatibility mode.

These settings could be added by Windows again later without your knowledge, so it’s useful to check again, especially if the issues reappear.

This guide is suitable for all versions of Windows that Steam supports.

This requires quick and simple editing of the registry. Make sure you only remove entries with «Steam» in their title at the locations below.

You may wish to Easily Back Up The Registry in Windows [www.howtogeek.com] before performing the steps below.

NB: The settings may be in one or both sets of locations listed below depending on if Steam was installed and used on the same Windows account and/or was used on a different Windows account.

For example: Steam could be installed and used on Windows account X and then also used on Windows account Y.

Using more than one Steam account does not affect this and you may not have all the folders listed below.

• Press Win + R and type regedit.exe and press enter or click OK.

• Navigate to the relevant section(s) of this guide.


• Navigate to: HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Compatibility Assistant\Persisted\
• Remove all entries with «Steam» in their title.

• From \Compatibility Assistant\, navigate to \Store\
• Remove all entries with «Steam» in their title.

• From \AppCompatFlags\, navigate to \Layers\
• Once more, remove all entries with «Steam» in their title.

If Steam is open, restart it.


• Navigate to: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Compatibility Assistant\Persisted\
• Remove all entries with «Steam» in their title.

• From \Compatibility Assistant\, navigate to \Store\
• Remove all entries with «Steam» in their title.

• From \AppCompatFlags\, navigate to \Layers\
• Once more, remove all entries with «Steam» in their title.

If Steam is open, restart it.

When the Program Compatibility Assistant message does appear, the Compatibility tab of the program reports that no settings have been applied (which is also the case if the message doesn’t appear), yet in some cases, Steam complains that it shouldn’t be run in compatibility mode.

In my case, both Windows and Steam didn’t warn that compatibly settings had been applied, which makes this issue even more problematic, especially when they can be applied to either Steam, the Overlay or the Steam Service and only a warning is displayed for Steam.

Before this fix, Steam was opening slowly, freezing frequently and hanging on «Preparing to launch. » for games. In addition, Team Fortress 2 froze for 10 seconds whenever the backpack, class loadout or server browser was opened.

After defragging, scanning for errors and scanning for viruses, the issue was still present. It was only after Windows stated that compatibility settings had been applied to «GameOverlayUI.exe» that the cause was found: In regedit under the compatibility layer keys, several items were listed with Steam, including the Steam client itself, which Windows had failed to mention before.

After removing all entries related to Steam, the client opened and logged in almost instantly. The «Preparing to launch. » window appeared for a much shorter duration before playing games too.

Later, after I bought new PC and installed a fresh copy of Windows, Steam was freezing while opening again. The cause once more was that Windows had applied compatibility settings without warning to SteamService.exe, with no warning from Steam either.

In addition, each time Steam is removed from: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Compatibility Assistant\Store\ and then Steam is opened, the entry is added again, although none of issues listed above reoccur after this single entry is re-added.

What is running steam in windows compatibility mode

This should work:

Right-click the shortcut you use -> click «Properties» -> go to the «Shortcut» tab if it didn’t open there by default -> click «Advanced. » -> check «Run as administrator» -> «OK» -> «Apply»

You should be able to copy that shortcut into the startup folder, then. First you’ll have to disable steam’s own automatic startup:

Steam -> Settings -> Interface -> Uncheck «Run Steam when my computer starts» -> OK

If you’re still on win7 like myself, then all you have to do is drag your modified shortcut into the «Startup» folder on your start menu. On win10, you’ll have to open the folder itself, which by default should be at:

then same thing, just drag and copy the shortcut to that folder. Should probably double-check that it keeps the run as admin setting, too, just to be sure.

Ok so first thing you want to do is go to your library in Steam and then go to the game you want to active Compatibility mode on right click the game and select proprieties from the drop down menu:

Then in the proportions windows that will open select Set launch options:

Then these window need to open:

Open Set launch options for the game you want to set

And you are done

If you like to use these with the Compatibility mode, make sure to add them in these order:

So first I recommend you try to find a crack and run it with that, see if that helps to run the game, its possible my issues is something else, my PC is piled up with stuff that can make a crash happen, as I use it some what as a development enviremnt and what ever the case that will likely be the first step to get it running
I also tryed to use it in a Virual Machine of Windows 7 and it just did not run, possible becouse the Virtual GPU is not supported, so may need to find a fix that way if cant find a way to make it really work on Windows 10, that sadly will be the first game like that so far for me

What is running steam in windows compatibility mode

I have changed my steam.exe’s property -> compatibility to make it so that it runs in administrator mode everytime, but whenever I open steam it opens up a pop-up saying that it’s running in compatibility mode.

Help on making so that steam always runs on administrator mode without the compatibility pop-up?

I have the same problem in windows 8.1.

I tried something:
In steam.exe’s properties -> compatibility tab, I selected administrator inside another menu, from the «all users», in the bottom of the compatibility tab.
For me, it worked, try it.

-OBD.: In windows 10, my recent upgrade, this problem returns, without solution.

There is no reason to run Steam as Admin. Doing so is a bad idea as it give admin access to everything launced through Steam.

For what reason do yo feel you need to run Steam as Admin?

I have installed MMORPG games that I would like to be accessed via my steam but some of them needs for steam to be running in admin to be launched properly.

I haven’t found any other solution for running these games using steam without having it run as admin so that’s why I’m running it as admin.
