  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.

• Error message: cannot access Windows Installer during the installation of Java SDK

  Original title: How To Install Windows Installer?

  OK, so I came to my laptop to do a writing in Word. Later, I tried to install the Java Development Kit, but he said something, of not being able to access Windows Installer. I ignored it and went to download a registry cleaner program to try to solve, but he also said "cannot access Windows Installer". Undertook research to install across the entire hard drive and the Windows registry and I found nothing. Not even the key MSIServer was there. I went to the Services and it was not there either. I opened my journal program, and he said that Microsoft Windows Installer has been deleted from the hard drive. The newspaper program that I use is open source and theres no script that writes, deletes, or replaces all files! So all I can do now is to install again, so I went to the Microsoft Download page: Windows Installer but when I tried to download mine)

  Do some basic cleaning and updates that may resolve your problem (also - check your time and date - as well as your setting time zone...)

  Search for malware:

  Download, install, execute, update and perform analyses complete system with the two following applications:

  • MalwareBytes (FREE)

  Remove anything they find. Reboot when necessary. (You can uninstall one or both when finished.)

  Search online with eSet Online Scanner.

  While probably not 100% necessary-, it is probably a good idea at this time to ensure that you continue to get the updates you need. This will help you ensure that your system update is ready to do it for you.

  Download and run the MSRT tool manually:

  Download/install the latest program Windows installation (for your operating system):
  (Windows XP 32-bit: WindowsXP-KB942288-v3 - x 86 .exe )
  (Download and save it to your desktop, run it.)

  Reset.

  and...

  Download the latest version of Windows Update (x 86) agent here:
  http://go.Microsoft.com/fwlink/?LinkId=91237
  ... and save it to the root of your C:\ drive. After you register on theroot of the C:\ drive, follow these steps:

  Close all Internet Explorer Windows and other applications.

  AutoScan--> RUN and type:

  --> Click OK.

  (If asked, select 'Run'). --> Click on NEXT--> select 'I agree' and click NEXT--> where he completed the installation, click "Finish"...

  You can disable hibernation if it is enabled and you do not...

  When you Hibernate your computer, Windows saves the contents of the system memory in the hiberfil.sys file. As a result, the size of the hiberfil.sys file will always be equal to the amount of physical memory in your system. If you don't use the Hibernate feature and want to reclaim the space used by Windows for the hiberfil.sys file, perform the following steps:

  -Start the Control Panel Power Options applet (go to start, settings, Control Panel, and then click Power Options).
  -Select the Hibernate tab, uncheck "Activate the hibernation", and then click OK. Although you might think otherwise, selecting never under "Hibernate" option on the power management tab does not delete the hiberfil.sys file.
  -Windows remove the "Hibernate" option on the power management tab and delete the hiberfil.sys file.

  You can control the amount of space your system restore can use...

  1. Click Start, right click my computer and then click Properties.
  2. click on the System Restore tab.
  3. highlight one of your readers (or C: If you only) and click on the button "settings".
  4 change the percentage of disk space you want to allow... I suggest moving the slider until you have about 1 GB (1024 MB or close to that...)
  5. click on OK. Then click OK again.

  You can control the amount of space used may or may not temporary Internet files...

  Empty the temporary Internet files and reduce the size, that it stores a size between 64 MB and 128 MB...

  -Open a copy of Microsoft Internet Explorer.
  -Select TOOLS - Internet Options.
  -On the general tab in the section 'Temporary Internet files', follow these steps:
  -Click on 'Delete the Cookies' (click OK)
  -Click on "Settings" and change the "amount of disk space to use: ' something between 64 MB and 128 MB. (There may be many more now.)
  -Click OK.
  -Click on 'Delete files', then select "Delete all offline content" (the box), and then click OK. (If you had a LOT, it can take 2 to 10 minutes or more).
  -Once it's done, click OK, close Internet Explorer, open Internet Explorer.

  You can use an application that scans your system for the log files and temporary files and use it to get rid of those who:

  Now that your system is generally free of malicious software (assuming you have an AntiVirus application), you've cleaned the "additional applications" that could be running and picking up your precious memory and the processor, you have authorized out of valuable and makes disk space as there are no problems with the drive itself and your Windows Update components are updates and should work fine - it is only only one other thing youpouvez wish to make:

  Get and install the hardware device last drivers for your system hardware/system manufacturers support and/or download web site.

  If you want, come back and let us know a bit more information on your system - particularly the brand / model of the system, you have - and maybe someone here can guide you to the place s x of law to this end.

  Original title: uninstall Windows Defender...

  I am running Windows XP, Vista or 7. I downloaded Windows Defender on the MS site some time ago, but now I want it out for GOOD.  Can I uninstall anything else on my list of programs except Windows Defender. When I asked him to remove the program, he said: I am running in SafeMode (no) or my Windows Installer is not installed properly (not). How can I get it my computer?  I put it there, I should be able to take off, it shouldn't I?  I wouldn't be able to decide what is on my own computer and what isn't?

  Hello

  1. What exactly is the error message you reciev when you try to uninstall Windows Defender?
  2. You have Microsoft Security Essentials installed on the computer?

  Microsoft Security Essentials has not automatically disabled Windows Defender in Vista or Windows 7, you must turn off to avoid conflicts. Windows Defender can't be uninstalled Vista or Windows 7.
  If Microsoft Security Essentials does not automatically uninstall Windows Defender on XP, you must manually uninstall Windows Defender through Control Panel of configuration/Add / Remove programs.

• Microsoft Security Essentials disables Windows Defender in Vista?

  Can error 0x800106ba on any attempt to open code I Defender. I also acquired McAfee at some point, but I uninstalled it hundreds of years ago but I still have the same error message whenever I try to open Windows Defender. Help, please

  It is not fair to McAfee posing problem with the Defender:

  Windows Defender:

  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.

  Hello, just to be sure I have the correct information, Windows Defender lights not in Windows Vista with Microsoft Security Essentials, as Essentials has its own version of the Defender.  The error code I received is the same as the previous posts in which is: 0x800106ba.  Again, just to be sure, I understand, I should stop trying to turn Defender because Security Essentials has covered it, okay?

  Hello

  Yes; Microsoft Security Essentials should disable Windows Defender for the reasons you mentioned.

  If she didn't turn it off, you should manually have to do it anyway.

  Q: is - this installation of Microsoft Security Essentials (XP/Vista/7) disable Windows Defender?
  A: Microsoft Security Essentials should disable Windows Defender in Vista and Windows 7, and then uninstall it from XP. In some cases, this does not happen automatically.
   

  Q: what happens if I do not disable or uninstall Windows Defender, if I use Microsoft Security Essentials (XP/Vista/7)?
  A: If Microsoft Security Essentials and Windows Defender are both running, your system can know the performance degradation and other problems caused by the conflict of two services providing real-time protection at the same time.
