Function for desktop computer keys does not

Hello

I have a desktop running Windows 7 Professional SP1 64 - bit OS.  With it, I use a Microsoft Wireless Keyboard 800.  I have used both for 4 years now without a problem.

Recently (last week inside or almost), the function keys (F1, F2, etc) stopped working.  All other keys on the keyboard work.  In addition, the virtual keyboard, the function keys work.

Any suggestions on how to fix this?  Everything I found online seems to be exclusive to laptops.

Thank you!

Brandon

SFC will produce this fictitious result, if one or both of these two Windows updates are installed on your computer.   Delete them.  They are not important for your computer.

SFC: KB3022345
SFC: KB3068708

Go to Windows Update. Lower left corner, click on view installed updates.  The display takes a long time to complete, so wait while the Green band moves all the way on the top of the window.  Now, type in one of these two KB codes in the search box.  If it is not installed, clear the check box for search and WAIT.  Enter now in the other.  If either are uninstall them.  Turn it back on.  Run the SFC.  If neither are installed, then come the real corrupt files in your operating system and the likely healing will be a re - install Windows 7.

  • Satellite A100-499 - function for the WiFi button does not work

    Hello, I have a Toshiba Satellite A100 - 499 PSAA9E.

    I formatted my laptop and installed XP with SP3. I downloaded and installed the drivers (in the right order) for this OS of the toshiba - Europe.com and everything is going well except Fn + F8. It is assumed that this combination has toggle Wifi & Bluetooth. When I switch side 'off' position and I press the keys, appears a message saying that I should switch to position 'on' but when I switch lateral position 'on' and I press Fn + F8 it does nothing.

    If I want to disable the wi - fi I have to do it with other methods: the function key does not work correctly.

    Any clue?
    Thanks for the advice (and sorry for my English).

    When the WLAN switch is on orange LED is also on?
    You can scan area available networks?
    Have you tried to use the WLAN without using FN + F8?

    Hey group,

    I just bought an i-Touch used on Ebay.  I have two computers: Dell 8300 and Toshiba Satellite.  Both run Win. XP SP3 (Build 2600 - Version 5.1.2600.5512) here's the twist: the laptop recognizes it is not the case of the desktop computer.  Suggestions for Apple do not seem to help me.  I downloaded the latest versions of i-Tunes for both systems.   Obviously, there must be a missing driver from Dell.  Help me Obi Wan.

  • Satellite A350-13 a - function keys does not work

    I have the Satellite A350-13. I installed Windows 7 for 2 weeks.

    The function keys does not work although I have installed the Toshiba value added package, which is responsible for the activation of the function keys.

    What the solution to this problem?

    > Function keys does not work although I have installed the toshiba value added package, which is responsible for the activation of the function keys

    Next to the VAP (value added package) you need to install the Flash Utility card support!
    Card Flash utility support controls the keys FN and not the VAP! But VAP is also needed.

    Ah! -in this case, it is not necessary.

    I see from my records that a similar case has been solved by uninstalling and reinstalling the update WAT - KB971033

    Open the Windows Update - click the link view updates installed on the left of the page

    in the list, find the WAT update KB971033, and then uninstall it.

    Then restart and reinstall the update from here - http://support.microsoft.com/kb/971033

  • I installed Vista in a Virtualbox VM and the product key does not work, how to fix this? I use the same product key supplied with the computer originally.

    I bought a Dell Precision T3400 of Dell Financial Services and it came with Vista Business installed.  I installed a new hard drive and installed Vista in a Virtualbox VM by using the recovery disk that came with the computer, and the product key does not work for activation.  I get a message that says I need to activate Windows, but he says that the product key is not valid.  How can I fix it?

    Thank you

    If you have reinstalled the OEM of Vista Business copy on the new hard drive, as Bill says you can't also use it in a virtual machine.

    You can only reuse your OEM of Vista professional copy if it is no longer used on the computer. Do you have what operating system installed on the new hard drive? It was an upgrade copy or complete the license?

    If you used a license to upgrade to another edition of Windows to replace your copy of company then Vista Business license is still in use (for upgrade) and you cannot reuse it in your virtual machine.

    However if you replaced Vista business with a copy of the full license of another edition then you are able to use the OEM copy in a virtual machine, but only on the same computer. You must use the product key from COA to the label on the computer. The product key is put in the copy OEM cannot find the SLIC table on the host motherboard. You must use the phone activation from within the virtual machine. Click on start in Vista Business and typing "slui 4. Do not meet the audio guests until it asks you if you want to speak to an agent. Explain that you have completely replaced the OEM copy with a copy of the full license of the new windows and now want to use the OEM copy in a virtual machine on the same computer. Agent will then give you the activation string. Remember that the virtual machine is not transferable to any other computer.

  • INSERT on X 240 key does not... for example when trying to use it with SHIFT-INSERT... why?

    The INSERT on my X 240 key does not work at all... either alone or jointly with another key like SHIFT - INSERT... Why?

    Press Fn + ESC to activate FnLock on and outside (for example make green LED come on and outside).

    As I explained previously, "Insert" is really "Fn - End" on X 240 keyboard.

    I checked it here, Shift-Insert works fine on X 240:

    • If FnLock is DISABLED, press Fn-shift-end

    • If FnLock is enabled, press SHIFT - end

    I tested in WordPad.

  • Meeting place for Dell Pro 8 Windows 'Physical' key does not

    Not really sure what's happening. Started using my Tablet earlier and the physical Windows key does not respond when I press it.  I had the time of the OS by using the Windows key on the menu of charms, but when you hold the camera in landscape mode I was already accustomed to hitting the physical key.

    Due to a recent medical procedure, I got to the House and I just stopped. The 14 return policy. Finally the mines is a 64 GB (which are hard to find) so I'll be without one for long.

    The only big change of the system in the last 24 hours has been updated the. BIOS A03 and 2 soundcards updates.

    Technical solutions or advice will be greatly appreciated. I want to repair RMA possesses only a LAST resort.

    OK, so I found the root cause of that I want to share. After spending my day to recharge this thing and everything works very well it happened again. This time I was aware of all my changes and was quickly able to go back and get fid of the problem. So for the node I'll call it a ' solution '.

    I am going to be angry with the accidental double taps. After reading a ton of information about tabletpcreview.com on this issue a gentleman he proposed a solution to disable this feature. Runs well you been out:

    Go to PC settings in the menu of charms, select ease of access, and the keyboard, you will find a setting called 'Keys filter' where the option is DISABLED by default. Turning IT will ignore brief repeated keystrokes. Well the minute I turned it on my physical key of Windows has stopped working. When I would turn it off, voala physical touch Windows started working again. I've repeated several times and can reproduce the problem.

    So long story short until this software bug fix to avoid using this feature.

    Hope this helps someone with this unique special cases.
