Aero in Windows 7 64-bit features disappeared

Running Win7 64 bit Ultimate. Aero features use to work properly, but have stopped.  There has been no change in the material.  Features such as transparency and Aero Peek doesn't work anymore. These features are not yet listed under Visual effects in the performance options and the taskbar, aero Peek is grayed out.

I tried

  • The resolution of problems in windows (a problem of transparencye...) and no returned error
  • A Microsoft 'Fix It' http://support.microsoft.com/mats/aero_effects_not_working/en-us, who told me that my hardware is not taken over, which is not accurate as Aero worked before and is or was compatible with my display unit
  • Update to the latest driver NVidia (although even once, he has already worked with the currently installed driver)
  • Checked the color settings on the monitor - true colors on both
  • Re-run windows experience index assessment (got 4.8, even that it was)

The only thing I have not tried I saw displayed was some registry changes.  I do not see why I would need to do this given he was working.  I'll do it if it corrects the problem.

Help, please.

PROBLEM SOLVED.  Found this article:

http://answers.Microsoft.com/en-us/Windows/Forum/Windows_7-desktop/after-22713-Windows-Update-Aero-features-stopped/a2befbe1-8C32-48ff-a5c0-c51d98a740fd

It turns out that a windows update caused the features to stop working, specifically updated platform for Windows 7 x 64-Edition (KB2670838).  Uninstalled that and everything is back to normal.

Quite frustrating to lose one day.

Now - can I mark my answer as the answer? :-)

    Have you installed Windows 7 device drivers for your make and model. If this is not the case, then go to the support web site factory and download Windows 7 drivers to a folder on your PC and then first install the drivers for the card mother/chipset, followed by USB, SATA, LAN, Audio and all other pilots.

    Also check the download site of the manufacture of the graphics card for the latest Windows 7 drivers for your card.

  • Aero Peak - window preview when hovering task bar.

    I just upgraded to office 2016. I seem to have lost the ability to hover over an icon in the taskbar and display the window without clicking in (for example, when you have several windows open work, used to fly hover to view details about a specific preview without having to open the window full). This feature did get turned off or deleted?

    Things I've done:

    Don't run the troubleshooter Aero - no problems found

    Updated - display driver has not corrected the problem

    I'm not very technical, so you help!

  • Firefox does not after clicking on the symbol, cannot remove firefox because it tells me that it is still open! Windows 7 64 bit

    Firefox does not at all. Would like to remove it and reinstall, however when trying to uninstall a message pops up that I need to first close firefox! In short: impossible to remove firefox, impossible to reinstall, cannot use it. Operating system Windows 7, 64 bit, Sony laptop computer VAIO PCG 81213 M. Firefox worked just fine before. IE works fine.

    This can help if you have had the same problem as me on the occasions.

    Right-click on an empty area of the taskbar. In the menu that appears, select "start Task Manager". Along the upper part of the "Task manager" window, select the 'process '. You will see a list of running processes. Scroll down the list until you see Firefox. Select it and press the 'end process' at the bottom right. Click 'end process' on the warning popup that appears. Firefox should disappear from the list. Now you should be able to start or to uninstall. If Firefox does not appear in the list at all so this fix is not for you. I hope this helps.

  • Satellite C670-13D: where can I find drivers for Windows 7 32 bit

    Hello

    Please, where can I find Windows 7 32-bit drivers for Satellite C670 - 13D Part #: PSC40E-004008RU.
    I need 'Value-added Package' to activate the hotkey feature.

    Thank you to.

    Hello

    Not seem that all Win 7 32-bit drivers are available for the C670 at this time.

    Since the VAP is not related to series of specific portable but the system (Windows 7 or Vista), you can use the VAP released for other series

    I recommend the C660 series and released for download the VAP.

  • Need a driver (Compaq 3611au) for Windows 7 64-bit

    Hello

    I recently installed WIndows 7 ultimate 64-bit edition. I use THE laptop Compaq 3611. I tried to download and install the drivers for Windows Vista 64-bit, but it only installed successfully display drivers. I can not find the drivers for audio, and other devices. Also my DVD stopped also detected after I connected by 3G idea.

    Can someone send me complete driver set for Windows 7 64-bit for Compaq 3611 to THE?

    Thanks in advance.

    Natasha

    Hi, Natasha:

    I was going to suggest that it might be a hardware problem, and now I agree with the person who said that.

    There are several models that had problems with the nVidia chipset (mainly running too hot), and he does strange things to the computer.

    Your PC is acting too irregular. It is indicative of hardware problems. Devices appear and disappear, and work then not work.

    I was going to same comment that Windows 7 must have installed a working audio driver, so at least your speakers would work. Sometimes, you need to install vista driver or a driver windows 7 HP, which gets the microphone to work.

    There is really no other insight, drivers or tips that I have in my bag for you help to get your PC to work.

    It may be time to give up on this one and get another laptop - same as a nice used one, then you can install W7 on that one and not lost your money on an operating system, that you cannot use.

  • Satellite U400 - update BIOS for Vista 32 bit to Windows 7 64-bit

    I currently have Vista 32 bit on my U400. I intend to do a clean install of Windows 7 64-bit. I downloaded all the necessary drivers on the Toshiba site for the 64-bit Windows 7 update. I noticed there is a BIOS of Vista 64 bit driver. Do I need to install this before you proceed with the installation or after?

    So, is there a particular order to install all the drivers, utilities and applications?

    Thank you

    Hey Buddy,

    Normally, this update of the BIOS must be made. You will need to use all the features of your laptop.

    I have improved my U400 Vista 32 bit to Vista 64-bit. After this update I started the update of the BIOS. Everything worked properly during this procedure because I closed all programs that are running (also AntiVirus/firewall) and was registered as an administrator.

    About installation order I didn t find a specific list, so I used this command:
    -Chipset
    -Display
    -Sound
    -LAN
    -WLAN
    -Card reader

  • How to manage Windows Vista power management features

    Hi guys

    I searched a bit in the technical knowledge of the Toshiba and found a very interesting article on Windows Vista power management features.

    * [How to manage Windows Vista power management features | http://aps2.toshiba-tro.de/kb0/HTD84026Q0000R01.htm] *.

    The fact is that you will not find one tool of Toshiba Power Saver on Vista as on Windows XP laptops and the parameters energy saver is a bit hidden in Vista power saving settings.

    But you can also control some options as a method of cooling or power saving Mode.

    I think that it could be interesting for some people here in the forum!

    Greetings to all!

    Thanks JayJay.

  • Can I put an old computer to Windows 7 (64 bit)?

    I have a desktop PC, HP Media Center m7260n, bought in 2006. At ran Upgrade Advisor: other than the need to do a clean install of Windows XP and an Aero compatibility issue, I respect the basic requirements. I have 5.5 GB of RAM installed, but it currently can only use about 3.5 GB of it. I know that I need a 64 bit OS to unlock the rest, but I clean up can I install an OS 64-bit on a machine with a motherboard ASUS P5LP - THE (HP/Compaq name: Lithium-UL8E)? I guess I am wondering if my computer's hardware is too old to install Windows 7 64 bit?

    Yes.

    What CPU is installed in your PC? If it's a Pentium 4 Prescott or Pentium D, then it is 64-bit capable.
