Disable Button In Device Manager Greyed Out


I am trying to disable a device in device manager of windows 7 64-bit pro. But the button is greyed out and in the drop down list (if i right click on the device) the option to disable is also not available. Is there a way to get that option back?

This is for the touchpad of my sony laptop. I want to use a little software i found that can automatically enable/disable the touchpad depending on the presence of an external mouse. But this software wants to disable the touchpad. But it can't because the option is missing from device manager.

How To Disable Back Button On Microsoft Bluetooth Mouse 5000?

How can i disable the back button on my microsoft bluetooth mouse 5000? I have the microsoft bluetooth mouse 5000. It works great and i love how much longer the battery life is with bluetooth over other usb wireless mice. One issue that i am having is that i keep accidentally hitting the back button unintentionally. This happens often when i am filling out long forms on websites, and i lose all the information i have already typed when i hit this button.

I have tried the intellipoint software, and there is no entry for the "bluetooth mouse 5000. " I have tried selecting other models, but there are none that work exactly right without causing some other undesired side effect. Is it even possible to disable the back button on this mouse? Is there any chance microsoft would ever develop drivers to include in the intellipoint package?

Usb Hub Displaying As Device In Device Manager

Pretty much all my device connected to my usb hub used to show in device manager as separate devices. However, they now only show under the name "kevin o'connor" (the name of my zune). Open the device's properties and going to the hardware tab will show all the device connected via the usb hub.

Therefore, all the devices do in fact work, it's just a little bothersome to me, and the fact that i can't safely remove anything from the hub without having to eject the entire hub. Here's a screen shot that shows what the hub shows as: http://i34. Tinypic.com/34fxmp4.png

Device Manager Error

A while ago, i needed to check on some drivers for an ir device and opened the device manager.
Sometimes, i have to do this regularly, but each and every time i try to open it, i get a message that says, "navigation the web page was canceled. " Then a message pops up that says mmc has stopped working. I am confused as to what is going because all other options/tools in mmc work except device manager. I have searched the internet all over for a solution, but can't seem to find a working one.

No Monitor Showing In Device Manager

I have a hannspree 28" monitor with an hdmi connection to an asus radeon 4890 graphics card. This set-up works fine in vista ultimate 32 bit in the screens default resolution of 1920 x 1200.
Ever since i installed windows 7 64 bit, in a dual boot scenario, i have been unable to get win 7 working correctly in normal mode, it works in safe mode but only at 1600 x 1200.

If i attempt a start in normal then the boot sequence stalls however i can open win 7 in normal if i remove the radeon 4890 from the display adapter element in the device manager. Win 7 installs the re-installs the 4890 but i can not get the correct resolution. With the latest ati drivers installed in the card there is no monitor showing in the device manager at all.

Hard Drive In Device Manager Can't Be Seen By Computer

Hard drive in "device manager" can't be seen by "computer". I installed a hard drive from a mac as a backup expecting that i could reformat it and it would all work. But, as far as i know, i need to be able to "see" it in computer in order to reformat it. It does show up in device manager. I uninstalled it, rebooted, and it reinstalled automatically, like it should. Still doesn't solve the problem.

Bsod When Opening System Items, Device Manager, Msconfig

I am encountering bsod errors when trying to open any item on the "system" control panel menu, the device manager, and when trying to open msconfig (among others). The following is a description of events leading up to the bsod errors:

1. I decide to upgrade to windows 7 pro from xp. My xp system has worked flawlessly for years. All hardware is working normally and is compatible with windows 7.

2. Windows 7 is installed on a freshly reformatted drive. Drivers and software are installed. All windows updates are applied. Everything is working perfectly and i can freely open device manager, any item in "system, " and msconfig etc. I have not attempted any 'tinkering' yet.

3. First bsod. I decide to edit pagefile.sys by turning off windows control and setting it to a custom size of 4096mb-4096mb. Windows immediately bsods. I restart and find that i can't access any of the windows system tools listed above and decide to reformat and start over (it was a new install and i had nothing to lose).

4. Windows 7 is installed as per step 3. I give pagefile.sys a wide berth and let windows handle it. I decide to perform some maintenance by disabling extraneous programs loading at startup using the program regseeker. I only disable unimportant things like adobe updating tools and the games platform steam etc. I open msconfig to confirm that the disabled startup programs have been disabled. Immediate bsod follows. I restart and find that opening "system" items, msconfig, and device manager all cause immediate bsod. In fact, i can't even right-click on my computer and select "manage" without causing a bsod.

All i can do at the moment is browse the internet and use other simple productivity programs. I can no longer 'tinker' without risking a bsod. I have tried using system restore to various earlier points. None work - i still experience the same symptoms. I have run memory tests on my memory.

I have not tried reseting my hardware because there is no reason to suspect they that have come loose (xp worked for years). I have not tried uninstalling and reinstalling hardware drivers, as i hope for someone to interpret my minidumps for me so that i can troubleshoot intelligently. I can provide said minidumps via the preferred method of anyone who can help.

Hard Drive Missing In My Computer But Visible In Device Manager

Hard drive missing in "my computer" but installed and visible in device manager. I have just purchased and configured a new computer, intel core i5 processor and asus p7p55d le motherboard with windows 7 64 bit home premium. I have 2 hard drives, 1 250 gig sata drive and 1 500 gig sata drive.
Windows is installed on the 500 gig drive.

In the bios i see both hard drives, in device manager i see both hard drives but in "my computer" the hard drive is missing, which means that i have no use of it. It is there as a scratch disk for the adobe suite of programs. I have tried to physically unplug the drive and re-install it, i have uninstalled it in device manager. I am at a loss why i cannot use this drive, does anyone know how to resolve this?

Error - "driver Is Missing" In Device Manager For Hp Printer

Original title: driver error message on device and drivers page for hp 309a multi function printer, i keep getting an alert message on my device manager showing an error for my multi function hp 309a printer. I have reinstalled the hp solutions software, and the software when downloading recognizes the pc is running windows 7. Furthermore, the printer works perfectly using wireless connection, when i print to it from word, for example. I keep seeing a yellow triangle on my pc device manager icon which suggests the driver is missing. How can it be missing when it is working correctly?

Some Of The Icons In The System Tray Are Greyed Out

Just upgraded from vista to windows 7 on a sony vaio laptop. Some of the icons in the systray are greyed out: e.g. Action center, charge indicator, internet access (router) and speaker volume. Is this correct? I would like the ability to see the signal strength of the router/access point that i am connecting to and the visual indication of the amount of charge remaining is also helpful.

Cannot Disable Dep

About a year ago i was having issues with dep preventing some of my programs from running. Within the last three months, however, dep has been shutting down several of my programs when i thought that it was disabled. Some of them get a message at the bottom left saying that dep shut them down, others get a pop up that reads "protection stub has stopped working, " and close. The list of programs affected includes solidworks, qtcreator, openoffice, java update, zoo tycoon 2, and rise of nations.

When i went to system->advanced system settings->advanced->performance settings->data execution prevention, all of the settings were grayed out. I attempted to re-enable dep by running bcdedit.exe /set{current} nx alwayson. Despite reporting completion, this did not solve my problem. I tried the same command but with optin and alwaysoff, but nothing changed, even after a reboot and using safe mode. Using wmic os get dataexecutionprevention_supportpolicy, i found that it was always set to 1, which means alwayson. This lends me to believe that the bcdedit tool is not working correctly.

I even system restored to my earliest restore point, but none of the dep related settings were affected, and the problem remains. Is there any other way to diagnose this problem further, or is there another way to disable dep?

Radio Button

My wireless internet stopped working on my laptop with windows 7, dell inspiron 1545. I reset my router and 2 computers connect with the internet just fine. When i try to connect the laptop, i'm asked to reset the radio button. The listing for dell is to hit the fn + f2 button. But nothing happens after waiting, redoing, restarting. I don't see an icon in the tray for radio or anything like it. I right clicked the "connect to" button to find available wireless, but nothing shows up. Any ideas what to do next?

How Can I Disable / Remove Photoviewer?

I have a canon powershot. It has a 16gb sdhc card - which the reader on my dell 2407fp does not recognize. No driver updates available either. Therefore, i plug the camera directly into a desktop usb port to view photos. Irfanview is my default image editor but when i click a pic in explorer the default is to preview (not open) and this function is automatically performed by (ugh) photoviewer - which is possibly the worst slowest most cumbersome image prog ever foisted upon the public at large. This driving me over the edge! How can i disable /remove photoviewer from my life?

No Log In Or Submit Button

When i want to log in to my email there isn't any log in button. I have to search all over to find where it is by clicking the mouse all over. The same happens on some games, or when i want to order something or doing surveys. It will say click submit and there isn't any button to click. In other words, those buttons or whatever you call them, have disappeared.

Reserve How Fn Button Works?

I have an hp g62-134ca. On my old computer (running vista) i used to use f2 to edit cells in excel instead of having to double-click. It saved me a lot of time. On my new computer (g62-134ca), the fn button works in reserved. In other words, if i press f2, the monitor brightness is decreased (f3 makes the monitor brighter). To edit an excel cell, i need to press the fn + f2 combo (or double-click with my mouse). I'm wondering if there's a way that i could reverse how the fn button works so that if i press f2, i edit an excel cell, and if i press fn + f2 i decrease the monitor brightness. Thank you for any tips!

Shutdown Button Sometimes Deactivated

I have a problem with windows 7 professional 64 bit. Sometimes the shutdown button is deactivated, i can see the button but can't click on it. Only with ctrl+alt+del it's possible to shutdown, log off etc. The error appears randomly so sometimes it works, and i can shutdown, log off etc. With clicking the button. It isn't a user-right based error because i have the problem with admin rights and also with normal user rights. I don't have a policy running where the shutdown button is deactivated. I installed the os with help of the waik tools, sysprep and a unattend.xml file but i don't set anything like this in the unattend file. Does somebody have any idea what it could be?

Mouse Click Ability Disable

I have a 1. 2 year-old daughter who likes to discover my laptop whenever possible. Thing is, that she is able to disable the mouse click ability just by sweeping over the keyboard; e.g. 30-40 keys pressed for a minute or two. Things do work, mouse moves, but when i go over something, it doesn't show any change or reaction for the mouse. It is if the mouse doesn't exist in the same reality as the computer -> a ghostly mouse.

It sometimes goes over in couple of minutes. Other times it stays until i restart the whole system. Today i tried ctrl+alt+del and at first there was no mouse activity either, but ~10 seconds it started working again. Any tips? How to fix-it or know the specific reason. P. S. Windows 7 pro x64
