Fix Windows defender 0x800700AA Error

Windows defender error 0x800700AA, service can not be started comes when the user is trying to run Windows defender scan on their system.
This kind of behavior happens for two reasons mostly, third-party application conflict or corrupted system files.

In this article, we will tackle both scenarios and provide you with solutions in both cases.

Third-party application conflict

In this rare scenario when Windows defender can not start scan due to conflict with installed service or application in the system solution is quite simple. Restart your PC into safe mode and run the scan from there. In a safe mode environment, minimum drivers and services are only loaded eliminating any conflicts that might occur when everything is booted. If Windows defender can not run the scan in safe mode and you get the same 0x800700AA error then you can eliminate application conflict as a reason and move to the next solution which will tackle corrupted system files. If you, however, managed to run a scan then you have a rare third-party application conflict, you can boot normally into windows and try to eliminate one by one to see which one is causing the issue. The safest bet would be to start with security software because most of the time that is what causes conflicts in running services and applications.

Corrupted system files

If the previous solution has not provided you with results then you have system file corruption that needs to be fixed. Move from one solution to another as presented below:

  1. Run SFC scan

    SFC scan is a built-in Windows tool for solving corrupted system files issues, it is fully automated and does not require from the user any kind of knowledge or information. To run it and scan the system do the following:
    Press ⊞ WINDOWS + X to open the secret menu
    Left-click on the command prompt (admin)
    In command prompt type SFC /SCANNOW and press ENTER
    Wait for the process to finish, do not interrupt it and once it is done, restart your computer

  2. Run DISM scan

    DISM scan is similar to SFC scan but it tackles different types of system file corruption and it is recommended to run it also after SFC has been completed. Please note that for DISM scan to be successful you will need a stable internet connection since DISM will replace corrupted files with new ones downloaded from Microsoft. To run it do the following:
    Press ⊞ WINDOWS + X to open the secret menu
    Left-click on the command prompt (admin)
    inside command prompt type: exe /online /cleanup-image /scanhealth followed by ENTER, then type: Dism.exe /online /cleanup-image /restorehealth also followed with ENTER.
    Leave scan to finish and reboot your PC

Taskbar is not visible in Remote Desktop
Recently, several users reported an issue on their Windows 10 computers where the taskbar is not visible when they tried to connect to a computer via Remote Desktop Protocol or RDP. The Remote Desktop Connection feature uses the RDP which allows users to access a computer remotely. This is actually different from the taskbar being hidden automatically until the pointer hovers on it since, in this scenario, the taskbar is completely not accessible which makes using the remote computer entirely difficult, if not impossible. There are several suggestions you can check out to resolve this problem, you can try to restart the process of Windows Explorer via Task Manager or you could clear the cache for multiple processes. You could also try to reinstall the Shell Experience components or show the local taskbar in the Remote desktop. Moreover, you could also try to update, uninstall or roll back the display driver/graphics card driver. For more details, refer to each one of the options given below.

Option 1 – Try to restart the Windows Explorer process

The first option you have to try to fix the problem with the taskbar is to simply restart the Windows Explorer process in the Task Manager.
  • Tap the Ctrl + Shift + Esc keys to open the Task Manager.
  • Next, go to the Processes tab and find the process of Windows Explorer.
  • Once you find it, right-click on it and select Restart to restart its process.
  • After that, restart your computer and see if you can now see the Taskbar.

Option 2 – Try clearing the cache of multiple processes

The next thing you can do to resolve the problem is to clear the cache of many processes in your computer. To do so, follow these steps:
  • Open the Notepad app and paste the following content in the text area:
@echo off taskkill /f /im explorer.exe taskkill /f /im shellexperiencehost.exe timeout /t 3 /NOBREAK > nul del %localappdata%PackagesMicrosoft.Windows.ShellExperienceHost_cw5n1h2txyewyTempState* /q timeout /t 2 /NOBREAK > nul start explorer @echo on
  • After that, tap the Ctrl + S keys to save the changes you’ve made in Notepad and select the “All files” as its file type, and then name it “CacheClearTWC.bat”.
  • Next, go to the location where you saved the file using File Explorer and then run it. This will run a couple of batch scripts which will clear the cache of multiple processes in the system.
  • Tap the Win + X keys and select the “Windows PowerShell (Admin)” option to open PowerShell as admin.
  • Next, execute this command in the command line: Get-appxpackage -all *shellexperience* -packagetype bundle |% {add-appxpackage -register -disabledevelopmentmode ($_.installlocation + “appxmetadataappxbundlemanifest.xml”)}
  • After the command has been executed, this will reinstall the Shell Experience components and should fix the problem with the taskbar.

Option 4 – Update, uninstall or rollback the Graphics card drivers

  • First, boot your computer into Safe Mode.
  • After that, tap the Win + R keys to launch Run.
  • Type in MSC into the box and tap Enter or click OK to open the Device Manager.
  • After that, a list of device drivers will be displayed. From there, look for the Display Adapters and click on them.
  • After that, right-click on each entry under the Display Adapters and select the “Uninstall Device” option from the menu.
  • Now restart your computer.
  • After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.
Note: You also have the option to go directly to the website of your graphics card manufacturers like NVIDIA, Intel, or AMD and go to the section called Drivers then check if there’s a new available update – if there is, download and install it.
