Windows 7 automatically switch to the basic theme (no aero). I need a way to disable this behavior.

This is very similar to what is described here: http://support.microsoft.com/kb/939423
And here: http://social.answers.microsoft.com/Forums/en-US/vistaperformance/thread/c7b869e1-5138-48a3-b09d-419f76e2f728

However, it's for Windows 7, Vista.

Scenario:
On a 3 screen inches (1920 x 1080 each) Setup ran on an ATI HD4890 (1 GB of RAM, 2 screens running) + HD 3450 (256 MB RAM, 1 screen running), whenever anything graphic intensive is put on the HD3450-driven screen, Windows will complain "the color scheme has been changed in Windows Basic - the color scheme current has exceeded its allowed memory. then the color scheme has been changed automatically to improve performance. Click here to see more information. "and change my basic theme Windows.

However, it is worth noting that the 3450 is not stressed at all (all the load is put on the 4890 according to GPU - Z).

It shouldn't be a problem with the system (6 GB, on Win7 x 64) RAM or processing power (i7 920).

Is there a way to disable Windows automatically "improving performance" by changing my theme?

Hi whsper,

Welcome to Microsoft Answers Community Forums.

Basically, the aero theme is enabled according to the video card.

Windows Display Driver Model is the architecture of graphic driver for video card drivers that are running versions of Microsoft Windows starting with Windows Vista.

WDDM driver model version 1.0 is that it does not support multiple drivers in a configuration multi-adaptateur, multi-screen, the latest version is 2.0 is introduced.

Windows disables the window manager of the Bureau (DWM) that controls the transparent glass effect or other effects of the Aero theme. The DWM manages the office and the main display settings in Windows.

I suggest you to check with your manufacturer for the latest drivers support your hardware configuration.

Hope this information helped you.

  • Windows vista x 64 comes back to the basic theme after update

    Greetings.

    Last night, I shut down my computer and helped my computer complete the necessary updates. However, during the update, I have no idea WHY MY THEME EXCHANGE this MORNING AFTER I POWERED on MY COMPUTER. IT IS THE SECOND TIME THIS HAS HAPPENED AFTER AN UPDATE.

    And you know what is more ironic, I CAN not EVEN FIND THE AERO THEME ANYWHERE IN customizations or anywhere in the computer! Mental right?
    I am very angry, because working on the base is very laborious and inefficient; the tabs are not the same, the interface is not as flexible and quite frankly takes a lot of getting used to.

    HOW CAN I GO BACK TO AERO AND ESPECIALLY WHAT HAS HAPPENED?

    Sorry for his appearances in anger, I'm very frustrated by this situation and I don't have the time to deal with this right now.

    Use a car running MSO. The first State is the intro. The second section opens. Set it to play once and stop image finally.

    Loy Vista doesn't have this option of cleaning disc for Windows Updates and in all probability that Microsoft will not implement what Vista is now in Extended Support.

  • Windows 8 shows the other user when I start. How can I disable this?

    When I start my computer, I get a screen that says the other user. I have to hit enter where the password should go and then I'll get the back button which will reveal my user account, but the other user account is listed next to it. I don't have an active guest account so I don't know what the other user account and I can't turn it off. I had my computer configured to just start up and go to my Start menu. I'm not sure but I think after an update to windows 8 a few weeks ago he has changed. I took the shot of what it looks like, but I'm not sure how to download on this forum. I looked to see if anyone else has had a similar problem, but I haven't seen any. Anyone know what is happening? Thank you

    Hello

    Before reinstalling the operating system, I suggest you update Windows 8. Check out the link to do so:
    "How do I restore, refresh or reset your PC.
    Read the sections "refresh your PC without affecting your files.
    Note: The applications that came with your PC or you installed on Windows Store will be reinstalled, but all the apps you have installed other Web sites and DVD is deleted. Windows puts a list of applications on your desktop after you refresh your PC.

  • Firefox tries to open a certain type of file (.spk) text and never adds an entry to the Applications tab in Options, so I have no way to change this behavior.

    Since it is not in the Applications tab, I can't change how Firefox handles it. And since it automatically opens it in a text file, I have no way to download this file type when it is bound to the JavaScript or flash because I can't right click and "save link as.»
    How can I make Firefox ask me how to handle the file instead of as text?
    I tried to remove "mimeTypes.rdf" of my Firefox profile.

    Therefore, there is no way to do what I want... to configure Firefox to ask what to do with the text/plain files instead of making them. I fell a feature request for it in the suggestion box.

  • Checked "Empty the Cache on exit" in Firefox 25. Now it hangs at startup. Is there a way to disable this setting apart from Firefox?

I created a new profile and it worked well. He's just stuck when I try to use my old profile. It doesn't work in either safe mode. Y at - it anyway to disable this option outside of Firefox.

    I also tried without downgrading to 24 and upgrade to the beta 26. None worked.

    You can check for problems with preferences.

    Rename or remove the file prefs.js and numbered possible prefs-# .js and the file user.js to reset all default prefs.

    You can try to clear the cache manually on the disk.

    It is best to avoid using external programs to clean your Firefox data and use integrated means that Firefox instead.
