Hello,
I am having trouble with Windows Defender and Update. I am getting error 0x800705b4 for Defender and though I've searched online on how to fix the problem none of them seem to work. Also, my computer won't let me access the update & security portion of my settings. When I click on it the window closes immediately.
RE : I am having trouble with Windows Defender and Update. I am getting error 0x800705b4
That error code usually happens, but not necessarily always because of that, when you have a 3rd party anti-virus program installed, such as Avast, AVG, Norton and McAfee. Those programs mentioned have their own defender and having 2 defenders running in the same computer will create conflicts, not to mention redundancy. Therefore, those programs will shut down Windows Defender.

Please disregard the suggestion posted below. I misunderstood your question.

Hi davidhk,
thank you for responding. I have tried your suggestions and I still have the same issues. I have found out that any windows store app, such as microsoft edge, news, and facebook will automatically close if I try to open it.
1. About Windows Defender. Do you have a 3rd party AV installed as suggested in my last reply ?Hi davidhk,
thank you for responding. I have tried your suggestions and I still have the same issues. I have found out that any windows store app, such as microsoft edge, news, and facebook will automatically close if I try to open it.
2. About Apps not working. Try this method...........................
Right click at it > click Command Prompt (Admin) > type powershell > press Enter key.
At the flashing prompt, copy and paste this command line ( to avoid typo it's best to apply Copy/paste method)......
Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)AppXManifest.xml"}
> press Enter.
3. If that does not fix the apps not working issue, try this troubleshooting ..............
Right click at Start button > click Command Prompt (Admin) > at the flashing prompt, copy/paste this.......
sfc /scannow
> press Enter.
It will take quite sometime.
When finished, it will give you one of the 3 reports...............(paraphrasing)
1. No integrity violation.
2. Found corrupt files and repair successful.
3. Found corrupt files but unable to repair.
If the report is #1, your solution lies elsewhere.
If the report is #2, check if your problems have been resolved.
If the report is #3, use this method................
In the same Command Prompt (Admin) windows, copy and paste this command...........
dism /online /cleanup-image /restorehealth
> press Enter.
Again it will take some time.
When finished, it will give you a report.
