Windows 7 has a nice little Windows Aero troubleshooting tool to find and fix problems with transparency and other visual effects, and then enable and turn on Aero support (and also Aero Peek) in Windows 7. If the tool does not work to enable Aero feature in Windows 7, the trick to force enable Aero in Windows Vista may still work in Windows 7.

Follow these steps in the instruction below to force enable Windows Aero Glass Transparency effect on system with video card (graphic accelerator adapter) that does not meet the WDDM (Windows Display Driver Model ) specifications, which provides functionality required to render the desktop and applications using Desktop Window Manager, a compositing window manager running on top of Direct3D 9.0Ex, and provides device driver interfaces required by Direct3D 10 runtime used in Windows 7.

  1. Open Registry Editor (RegEdit).
  2. Navigate to the following registry key:

    HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM

    If the DWM registry key is not found, right click on Windows and then select New -> Key to create new branch and name it as DWM.

  3. In the right details pane, create a new DWORD (32-bit value) named UseMachineCheck, and set its value to 0.
  4. In the right details pane, create a new DWORD (32-bit) Value named Blur, and set its value to 0.
  5. In the right details pane, create a new DWORD (32-bit) Value named Animations, and set its value to 0.
  6. Restart the Desktop Window Manager Session Manager in Services in Control Panel (type Services.msc in Start Search), or run the following commands in a command prompt with administrator privileges:

    net stop uxsms
    net start uxsms

  7. Attempt to enable and apply Windows Aero in Windows 7. Restart the computer if required.

The trick above also may work to enable Aero on Windows 7 and Windows Vista installed on virtual machine (VM), especially in Virtual PC 2007. VPC 2007 uses S3 as virtual display adapter, which is capable of running Windows Aero. When the guest Windows 7 or Vista OS uses software-based hardware check after hack above, it will find only S3, couple with actual Aero-capable video card, may allow Aero to run in VMs as in real physical machine.

  • KING

    dude it freezed

  • Swizzle

    This works until I reboot, then I seem to have to do it all over again. Went into msconfig (type this in Start -> search window) and go to Startup tab. Look for Quicktime and uncheck it. You can also Uninstall (which I thought I had done already) and make sure to select Uninstall Everything option. Hope this helps anyone that had my issue.

  • kyle

    dude THANK YOU VERY MUCH for this.. my Aero was enabled again….

  • Mani

    I dinot get the last step can any body help me plz

    • Anthony

      On the last step you need to click start, type in CMD, right click CMD and click Run as administrator. Once open type in net stop uxsms, then when it has stopped restart it by typing net start uxsms

      These steps did not work for me and I had heard that it is probably the graphics card driver or the motherboard. These were working for me but have stopped so guessing it is something I have installed. I’m going to try the repair windows option then if not I am going to reinstall windows 7. Should work that way πŸ˜€

    If after restarting the computer nothing has happened try the following steps:

    1. In your start search type in again "Services.msc" without quotes and press enter

    2. Search for the Themes services.

    3. Restart the Themes services.

    Does not work you idiot publish a new trick on which i can enable it on windows7 enterprise build7601 sp1 and the option for aero did not come in advance system settings or any where and no difference came in my system

  • Sam

    I've done this one 2 machines with success as well as another machine that was not able to do it. This hack does not "Force" it so to speak like I think some are expecting if your computer does not support WDM 2 it will not work however, on older machines that do support it but, in which windows has automatically detected the hardware to be below what seems like somewhat of an arbitrary standard it is disabled to start (why they don't just check for WDM 2 support is beyond me)

    However, the two machines that I did "force" this on did have somewhat of a performance loss in window browsing however, I much prefer that than the "grey"-ness.

  • disi

    I couldn't get this trick to work, running Win7 in VirtualBox. Even with the Direct3D enabled, being able to play 3D games, Windows will not turn on Aero because the driver is not WDDM (signed by them).

    Anyway, good tip and worth a try. The people talking about reinstalling Windows are just idiots πŸ˜€

  • ahmed

    it works thank you so much

  • CJH

    Thanks so much! – I actually already had a regeistry key in HKEY_CURRENT_USERSoftwareMicrosoftWindowsDWM called EnableAeroPeek. Something changed the value to 0 and I was not able to reenable through normal means, but chaning the registry key value to 1 solved the problem. Thanks so much!

  • Pat

    This trick didn't work for me either, but I find out why Areo didn't work. The video card on my Windows 7 64bit machine was using 16 bit High Color settings instead of 32 bit True color settings.

    A bit strange Windows 7 could not tell me that that was the issue.

  • Peaches

    i didnt do the hack, insted i noticed thatin the reg key there is on called "enable aero peek" mine was set to zero, i changed it to one and now aero peek works like its suppose to.. might want to try that before doin the hack it may or may not work for ya..

  • Kathy

    It Worked!! Yea! Wish I had found this site 3 hours ago. Thank you!

  • Mike

    I tried this very carefully, and I got nothing. When I try to change themes, only the background changes, no Aero. on Build 7100 with intel 915.

  • Gal

    I follwed the instructions, and it's not working for me.

  • DD

    hey "rt", comment #30,

    i have an intel 915 chipset too, could you notify me should you find a solution? i know there HAS to be a way because from running some 3rd party apps, the graphics card is able to create (or replicate) the transparency effect… ([email protected]) thanks!

  • eee pc 701 user

    This will NOT work on asus eee pc 701 it will turn the screen black and just left the watermark

  • joe

    I was wondering if anybody knew if a Intel GMA 900 integrated graphics would work… On wikipedia it says it theoretically works but there is no WDDM driver so this is what this hack is for, right?

  • rt

    this does not work.. any other solutions for that? I have a intel 915 on my notebook, so I need a hack to enable aero..

  • sendblink

    Those last 2 comments 27 & 28 are complete bullshit this does not work on RTM, I know this because it worked for me fine on the beta versions *Before RC… then the rest *betas after RC it stopped working.

  • fabiode34

    this worked fine on Windows 7 Final Version.

  • Glenn

    This WORKED for me on Windows 7 RTM!

    After I installed my ASUS Radeon 4870 Dark Knight 1GB, aero stopped working and the Win 7 fixer couldn't fix it. This "hack" did the trick!

  • andy

    1 Read the article carefuly

    2 comments allready state that this does not work

    for those who screens turned black, you need to have had met all hardware req.(128 Mb vcard) but didn't have driver

    if you had req., nothing should have happened instead of a black screen

    this is a vista and early w7 trick

    does not work for later and rtm

  • FoXik0169

    You must write in HKEY_USERS"YOUR USER ID"SoftwareMicrosoftWindowsDWM

    But is render only black screen(on my computer). πŸ™‚

  • wayne

    it is useless to enable aero in 7 rc by using hacks i tried every method and the screen gone black……

  • Jrip

    Y'all are idiots. this doesn't work unless your graphics card has 128 MB or more in memory. unsupported means cards that would be able to run it as far as specs go but cant because the driver is unsupported.

  • David

    lier!!!!

  • lex

    my screen when black also a easier way then going into safe mode is to use ease of access and choose use the color setting it will fix it enough to delete the registry u added

  • Win 7 King

    Windows 7 rocks, and my cousin liked using it on my PC. We installed it on his older laptop, and YES IT RAN! Trouble to find drivers for the ex-Windows XP machine but no biggie. Got it goin' sweet. THEN THIS DOUCHE GIVE OUT THESE BS DIRECTIONS. SUCK A HOT COCK…NEEEEWB!!!!

  • Win 7 Pimp

    Listen dickhead… You probably don't even run Win 7 so don't go speakin' on shit you don't know hoe! You fuckem my cousin's shit up..and you're an idiot. THIS IS A TWEAK THAT I HAVE USED ON VISTA..DO NOT ATTEMPT ON WINDOWS 7!!! instead of forcing "Aero", how about I force your jaw shut..with steel wire bitch?! Get some!

  • MAD MAN

    YOU ASSHOLE I HAD TO REINSTALL WIN 7 CAUSE MY PC WONT GO INTO SAFEMODE UNLESS I BOOT INTO NORMAL MODE AND RESTART IT FROM THERE THEN KEEP HITTING F8, IN SHORT TERMS DONT DO THIS ON AN MDG WIN XP SYSTEM

  • steve

    Can be a dangerous thing to do. So before you touch the Registry, use System Restore to create a restore point so that you can revert to the previous version of the Registry if something goes awry.To create a restore point, choose Control Panel > System and Maintenance > Restore files from backup > Create a restore point or change settings. GL. just for any1 reading this.

  • latinman

    That doesn't work at all!

    Please try to find any loophole, and maybe you should try it out yourself before posting and ruining some people's PCs.

  • Srinivasan S.R.

    I have tried the method you suggested…. Unfortunately, it doesn't work at all!! I am using Windows 7 RC build 7100 and I can't even get the Aero theme enabled. The display on the screen is just like Vista Basic and nothing else. When I click on any of the Aero themes, say 'Characters', 'Nature', etc., only the wallpaper changes and not the look and feel. πŸ™

    I think Microsoft has fixed this loophole. Try to find another way in which you can enable Aero on Windows 7.

  • Larry Miller

    This method will not enable Aero to work with VirtualPC. VirtualPC does indeed use S3 as the emulated video card. But this card has had many versions, the version emulated on VirtualPC is a very old one with specifications well below the requirements of Aero. The hardware that is emulated in VirtualPC was chosen for maximum compatibility with client operating systems and applications, not maximum capability.

    However, some users have used a different method that seems to work. Using this method the client attaches to the host system by means of remote desktop. I have not done this. Do an internet search for "VirtualPC Aero" to find the details.

    IDIOT you screwed my pc .

  • Al K. Hall

    Does not work here either???

  • Anonymous

    DOES NOT WORK. ROYALLY SCREWS UP WIN 7. IF YOU USED THIS THEN GO INTO SAFE MODE AND REMOVE THE REGISTRY VALUES TO FIX THIS.

  • blacknight

    Well It did not worked for me on a Gforce TI 4200 It looks it was working but the screen was stucked no movement, but it was working normal in the background. I had to start windows again in safe mode and remove the registry values. Good Luck!!!

  • How to activate Aero now?

  • "Create a new DWORD.. value is 0"

    Hexadecimal or decimal?

  • To run cmd as administrator, you must right click cmd, and click 'Run as Administrator'.

    Also I can't get this to work either. :

    No aero, I followed everything correctly, and no errors.

  • Yamcha

    This actually ruined Windows 7 for me, the screen would be blank after i applied the settings and did a restart.. luckily it was for my sis so no big deal i guess.. but this doesnt work..

  • Adrian

    I also tried this hack while using Virtual PC SP1. It did not give me aero. πŸ™

    Getting a Windows Experience Index is apparently a critical step and when I try to run it there is a message "Unable to run an assessment inside a virtual machine". Also the emulated S3 video card has 8MB video memory – a tiny amount – my GeForce card has 512MB. So I am not surprised by no aero.

  • rob

    i'm trying these steps in virtual pc 2007 right now. the registry has been edited and the desktop window session manager restarted.

    now i don't exactly know what to do to enable aero.

    any suggestion? :/

  • hahaha

    u hav 2 right klik cmd and say run as administr8r!

  • Tanner

    when i put in the command in cmd it says

    sysetm error 5 has occurred

    access is denied

    is it an administrative thing?
