• Cannot start Windows Defender getting error 0x8007042d

  I tried to turn on my windows Defender, but when I do I get this.   Error 0x8007042d service is not started because of the failure of log-0n. How can I fix it?

  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?

• Windows Media Center Gets error: invalid Application - cannot start

  Windows Media Center (of the month last Vista 32-Bit)

  I have problems to make internet TV, news and Netflix to connect to the internet when you use Windows Media Center.  They are all under the TV + movies option during the WMC.  I get an error saying [invalid Application - cannot start "" ""].  Not sure if this is because the internet connection that I use is not one that has a user name or password.  Not know how to configure it for this version of Windows.  I don't get this problem when you use Windows Media Center in Windows 7.

• 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

  "Error: 577-Windows cannot verify the digital signature for this file."  "A recent hardware or software change might be installed a file that is signed incorrectly or damaged, or maybe it's a malicious software from an unknown source.

  So I searched around this error and found the instructions in the support forum to change the settings in the following registry keys

  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.

• Cannot start Windows Defender.

  Original title: windows Defender.

  Windows defender is turned off and I can't turn it back on, everything I try but it doesn't work. It is already on my laptop, I don't know what to do... Need help.

  If you have Microsoft Security Essentials, AVG, McAfee, Norton, etc. installed, they have a conflict with Windows Defender, or turn it off.

  Microsoft Security Essentials has its own integrated version of the defender and should automatically disable the version of Vista in Windows Defender.

  If it's not:

  http://Windows.Microsoft.com/en-us/Windows-Vista/turn-Windows-Defender-on-or-off

  Turn Windows Defender on or off the information on the link above of Microsoft.

  Hope the above explains the common compatibility issues with Windows Defender and other security programs.

• Stuck on the screen of HP recovery and cannot start windows

  HP Pavilion
  Model: 17 - 1215dx
  
  If you need the serial number or the fn, just ask. I didn't post too much sensitive information.
  
  It was originally 10 64-bit windows... but now has 8.1 Windows 64-bit
  i5 8gig of RAM processor
  
  Literally just close the lid and open it upwards and it wouldn't boot windows. It is stuck at the screen HP saying it's diagnose my problem. Tried a soft reset and a hard reset when you remove the battery and put it again while it is unplugged. Did not help. I can't start in safe mode. I tried to do a restore which has been a success but it restarts when he says "there was a problem, restart your PC. I'm frustrated and reset a factory and the same factory reset was successful and was when he came back to 8.1 because it's the OS, I bought it with but then it still wouldn't let me in windows. I was going to try and start to repair, but if I had known this would require an administrator I'd never have done the factory reset. I know I've been reckless, but I just wanted to work. But yes, I don't know what the problem is. I feel like if it was a hardware problem is just something to keep windows to operate. Should I try a repair disk? Would that help?

  The SecretLight

  Hello;
  
  Let me welcome you on the HP forums!
  
  I read your post you need to grab your laptop and wanted to help - but we need more information.

  You said that your laptop came originally with Win10, but then later, you said you tried to go back to Win8.1, you can then said, it's the original OS.

  So, who was the original - Win8.1 or Win10?

  Ask because if it came with Win8.1 and you UPGRADED to Win10, while Microsoft tells you that there is no risk in the upgrade of Win10, because they allow you to believe that you can always go back to your original OS and setup within 30 days, the ugly matter faction is that the Win10 GoBack feature turned out to be unreliable - and when it fails She can let the machines in a corrupt State - which is not always the case, it happens often enough to be a problem, but you will get no warning beforehand that he goes to the trash your PC!
  
  The Win10 upgrade is known, in some cases, corrupt the partition of recovery that are stored by the OEM that built the original machine.  It's pretty much guarantee that no HP recovery will work.
  
  What will work restores your computer to its original factory state using HP recovery media. It is a set of DVD and a CD or a USB key, which will erase the hard drive (removing all data, applications and settings, reinstall the original OS, drivers and utilities for HP. In some cases, you will be able to order a USB instead of discs.  You must order at HP; they cannot be downloaded.
  
  You can look online for recovery from the paged media related: http://support.hp.com/us-en/drivers
  
  Once there, enter your product name or number. On your software page and download the drivers, select your operating system and version. Click on "Update".  If the HP recovery support is available for your computer, down near the bottom of the page, you will see an entry for the command Recovery Media-CD/DVD/USB. Click on the symbol '+' to expand this entty and click on order to press for more details.
  
  Or, if you prefer, you can do the same by contacting HP Customer Service:
  
  If you live in the United States or the Canada, details are on this page: http://www8.hp.com/us/en/contact-hp/phone-assist.html#section1
  
  If you live elsewhere, contact details are on this page: http://www8.hp.com/us/en/contact-hp/ww-contact-us.html
  
  NOTE: once you get through, stay on the line until you are finally able to talk to someone ' one - it can take a while!

  Good luck

• Satellite C660-171 - Bluescreen and cannot start Windows

  Hello

  So I start my laptop the password set in get a DRIVER_IRQL_NOT_LESS_OR_EQUAL blue screen, then it starts initially on screen then I go to safe mode, then I still get a blue screen that says problem detected Windows stop!

  So, how to move the stupid laptop is old only 2 days is there a way to restore to factory settings or uninstall certain things to try to fix? I'm not too computer savvy so any help would be appreciated

  > is it possible to restore it to factory settings
  If you had read the manual you would know how to restore laptop to factory settings ;)

  Still if you also get a bluescreen mode safe, that there seems to be a problem with the installation of the OS and you must restore it back to factory settings. Therefore, you can use the recovery disk as described here:

• Satellite A300-20F - Bluescreen and cannot start Windows

  Hello
  I have A300-20F

  I installed a new clean vista with my spare drive because I was taking dead bluescreen errors but today I took some of them... I had installed my all drivers updated.
  now the situation is the following:

  I can not open vista. When I try to open in safe mode it gives BSOD that I do not see what are these codes. I try to open with my spare drive, but it says firstfully: "windows is loadind files" then gives me an error:

  file: windows\system32\boot\winload.exe
  Status: 0 x 0000001
  The selected entry could not be loaded because the application is missing or damaged.

  What can I do now? I can't open anything now! Show me a way please... (he gave me a lot of mistakes, so couldn't write down them)

  Hi dunkerman,

  If you can start t in Windows in safe mode I think some Windows files are corrupted or something went wrong during the installation of the driver

  You wrote that you have installed a new clean Vista with your rescue disk. This means that you have used the Toshiba Recovery disk or a normal disc of Microsoft?

  Usually, if you install Toshiba Recovery disk Windows all drivers and tools will also be installed because the disk contains a ready image of factory settings. So generally with these settings, everything should work fine then I recommend to test again with a recovery disk.

• Get the error code 641, cannot install Windows updates.

  Reluctant to do a reinstall of windows.  I had the same problem, find the same useless information on a cure.  I did a reinstall of windows (Vista) and partially by installing the updates of windows I ran into the same problem again, the windows installer does not.  Even from scratch will get not anywhere, leaving you at least your system as it stands leaves can be used instead of a partially updated with no program system.

  I wonder if Apple has this kind of problem?

  Hello

  I suggest to reset the Windows Update components and check if it helps.

  Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs.

• 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.
