Hi John,.

Thank you for your update on the issue.

Before a new image, I suggest you to reinstall the USB controller drivers and check the status.

Remove and reinstall all USB controllers.

  1. Open Manager devices by clicking the Start button, click Control Panel, click system and security, and then, under System, clicking Device Manager. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
  2. In the list of the categories of equipment, locate and expand Bus USB controllers.
  3. Right-click every device under the Bus USB controllers node and then click Uninstall to remove them one at a time.
  4. Restart the computer and let the USB controllers get reinstalled.

Plug in the removable USB device and test to make sure that you do not get any problems to connect external USB devices.

Please post back your results for assistance.

    However, the requirements for the media upgrade is that you have an operating system already eligible such as Windows XP or Vista installed to use it. Since the Windows 7 end user license agreement.

    15 UPDATES. To use upgrade software, you must first be licensed for the software that is eligible for the upgrade. After the upgrade, this agreement takes the place of the agreement for the software that you upgraded. After upgrade, you can no longer use the software that you upgraded.

    So, if you are always denied, you will just have to reinstall Windows XP or Vista and let it do the verification of eligibility.

  • Can't change screen brightness in Windows 7 Home Premium 32 bit?

    I recently updated my old A305 laptop Toshiba Satellite Windows Vista Home Premium 32 bit for Windows 7 Home Premium 32 bit and it does not allow me to change the brightness of the screen, when I use the sliders, then click on save changes, nothing happens, tried to restart anything, tried the monitor generic PnP Manager peripherals/monitors/uninstall and nothing happens , can someone please help me my screen is literally blinding my eyes!

    Hello

    Thanks for posting your query in Microsoft Community.

    We would be happy to help you with the problem you are facing today. I understand the difficulty.

    Here are the instructions for setting the display brightness. Basically you can adjust the gamma in Windows or adjust the brightness on the screen itself:

    Within the BONE:

    1. press Ctrl + ESC, then type "control". This will put you in the control panel.

    2. double-click on the display icon.

    3. Select "Calibrate color" icon located on the left side of the screen next to a blue and yellow shield icon.

    This wizard provides a walk through to adjust the settings of your screen for the color and the brightness of your monitor setting.

    The Wizard "calibrate color" is good to cross, but the area you want to adjust brightness would be the page titled 'adjust gamma. You can adjust the settings until the screen has the brightness that you prefer.

    See also the link below.

    Adjust the brightness and contrast of your monitor

    Thank you.

    Yes, you can upgrade from Windows 7 Home Premium 64-bit for Windows 7 Ultimate 64-bit. You do not lose the pre-installed software & drivers, if you upgrade. If you perform a clean install of Ultimate, you will lose all the pre-installed software.
