  Verify that the following Services are running.

  "Windows Update" and "Windows Defender".  To join the Services type services.msc in the start / run box.

  Some anti virus programs can disable Windows Defender to avoid any conflict in operation together.  What anti-virus software are you running?

• Cannot start Windows Defender - registry keys missing after uninstalling Avast

  Hello

  I am running Windows 8 on a laptop Samsung.  I recently installed and then uninstalled Avast antivirus.  In fact, I was unable to uninstall using the uninstall of WIndows process, so I downloaded Avast uninstaller to remove the program.  When I tried to reboot Windows Defender I got the following error message

  Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender\DisableAntiSpyware
  Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender\DisableAntiVirus

  The problem is that they do not exist on my laptop.  I can not find them.

  all the ideas that everyone thank you

  Hello

  If you use Norton, AVG, Avira, Microsoft Security Essentials, McAfee, etc. the default action is for Windows Defender must be disabled, that these AntiVirus programs have their own Antispyware Applications.

  There is nothing to worry.

  Using both programs at the same time can cause system conflicts, etc.

  If you are using one of the above AntiVirus programs, this Information from David O - Support Engineer shows you how to manually enable Windows Defender (disregard information from uninstalling; not possible in Vista):

  http://answers.Microsoft.com/en-us/Windows/Forum/windows_vista-security/how-do-i-manually-start-Windows-Defender-in-Vista/dab845b2-9ba5-47F3-9518-c4c6781e7d5b

  "Go to start, Control Panel, Administrative Tools, Services. Look for Windows Defender.

  Right click and select Properties , ensure that Startup Type is automatic.

  Once modified, click apply and OK.

  Quit and restart your computer. Check the back take the same path to confirm that Windows Defender has started"

  If you want to have additional protection against malware using the version FREE of Malwarebytes AntiMalware:

• Satellite A660-158 - cannot start Windows

  Toshiba Satellite A660-158

  I bought a laptop Toshiba Satellite A660-158. It has served me less than a week. I think it's the broken hard drive.

  My problem:
  Once I start the computer, it started and has worked for a while, but suddenly, there was an error reading that I didn't have the time. Computer has been restarted. And does not load... Until the boot mode does not reach. But the initial test (with logo) succeeded. Takes a long time and finally gives an error:
  -----
  Cannot start Windows. Maybe it was because of the recent small difference is the hardware or software configuration. To fix this error:
  1. Insert your Windows installation disc, restart the computer (the complete transmission wasn't)
  2. choose the language settings, and then click Next.
  3. Select "repair your computer".
  If this disk is missing, contact your system administrator or computer manufacturer (he turned and said to wear to the DEPOT, but I do not have this feature).

  Status: 0xc000000e

  Details: Unable to start menu, since the required device is inaccessible.

  Hey,.

  And why do you think the hard drive is faulty?
  Have you ever tried the repair your computer option? Usually with this option you can restore factory in a few minutes.

  Also if you have the Toshiba recovery disc you can also restore the factory of this disc. Just boot from it and follow the instructions on the screen. You need to do a few clicks only, installation with all the drivers and tools happen automatically.

  If you have any other questions, please let us know! :)

• Satellite L40 - cannot start Windows

  Hello

  hope you can help, my computer Toshibal L40 laptop on commissioning began by displaying the following error message:

  * "Cannot start Windows. a recent change in the software hardware might be causing... » *

  It offers the possibility of:
  "* Launch Startup Repair option" * "

  I chose this. WIndows seems to load up, but then I get the following error message:

  Installed program cannot start. Click OK to turn off the computer *.

  I lost the recovery disk, but attempted to load the recovery console by using a windows XP disk, but it gave me error message more. Advice would be very welcome.

  For the installation of Vista you don't need SATA driver but for Windows XP Home edition you need. Is no problem at all.

  The question is what you want to do now? If you want to use Vista just use recovery media and you will have factory again.
  No problem at all.

• Cannot start windows after update

  After you install a windows update, my computer cannot start windows, when I boot it.  It seems the windows files.  I don't have a recovery disk (lesson).  I have windows vista, is there anyway to restore windows on my PC other than buying the software.  I confess that I do not download updates often... that is why... It's always trouble.

  Hi, MooreTM,

  Brand and model of your computer, please.  Thank you.

  (1) you are able to start safe mode and do a system restore?

  Start the computer

  Start typing F8

  Select Mode safe mode with networking

  Select a date and time before the Windows update that caused the problem

  (2) start Windows and tapping F11 key

• Cannot start Windows, Windows Setup does not detect the hard disk, Bootmgr is misiing

  I have a few problems on my laptop [Acer 3810 t]

  -The first problem
  My mobile give me screen "cannot start windows' who have 2 choices: run the Startup Repair tool and boot normally. I chose to fix it, but nothing happens and stuck "starting windows" and gives unmountable boot volume 'blue screen '. the Dungeon of blues screen appear (for laptop is a not restart). So I turned off my phone and turn it back on it. the "could not start" screen again and I chose to start normally. but the result is negative. My portable Dungeon cannot start windows. Because of that I am using the advanced boot option and choose all the boot type such asit cannot load the safemode, last configuration etc, but the result is the same, you cannot start windows. in safe mode, its stuck in loading fileinfo.sys. I do not give up to try again with the advanced boot option. until I have a bad situation. My laptop can only 1 file in safe mode and blues screen do not appear again (my laptop only return at the beginning of start or restart)

  -The second problem
  because it cant solved, I want to reinstall my laptop. My OS is Vista 32 bit (pre-installed). I want to install the new operating system, windows 7. I use Dsik Flash bootable USB to install Windows 7. But in the BIOS, it is detected as a USB HDD. So I set my BIOS to load USB HDD to the first order. the installation can be done, but only until the "start Setup" screen and its deadlock. I have it wait up to an hour, but nothing happens. So I'm going to BIOS, change SATA mode to IDE mode AHCI. Then load the USB and go "installation program start screen. but the new problem is the installation of window does not detect my hard drive. So I can not choose the place to install the operating system. I have to load the driver, but I did not. Again to load the configuration to AHCI and IDE, until I get my HDD can detected in IDE mode. So I think I can move easily, I choose custom installation and choose the hard drive to install the operating system. But unfortunately, at the beginning of the process, after choosing the OS, the Installer gives error if installation location the installation failed. (I forgot the error message)

  -The third problem
  So far, I can't spend 'startup begins' as well in mode IDE and AHCI. Also bootmgr in my hard disk is missing, so I can't go to move the startup repair or the startup option in my HDD as before

  What is the error code that you got with blue screen?

  I think that there is a problem with your drive HARD check that by contacting acer...
