Windows 10: How do you create windows defender service using command prompt?

My pc was infected by malware which corrupted the windows registry and I had to do a complete reset to see if I could undo the damage.

Ever since the reset, windows update and windows defender services have been removed from the services list and I have to manually type in a code in the cmd to restore the windows update service upon every restart of my pc.


The code I type is "sc create wuauserv DisplayName= "Windows Update" binpath= "C:\WINDOWS\system32\svchost.exe -k netsvcs -p" Start= delayed-auto depend= RpcSs"

I also have to delete the registry key "wuauserv" from 'Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\wuauserv' and import it back again so that it can work.

I got this clean registry key from a clean computer


I want to try the same for windows defender having obtained a clean registry key but everytime I type the following command in cmd "sc start WinDefend Enable" I get the following error ;

StartService: OpenService FAILED 1060:

The specified service does not exist as an installed service.


Meaning I need to create the service first before I can run it and I don't know the cmd code for doing that.


As of now I have no security providers and realtime protection.

command prompt will not open in safe mode with command prompt

Would I just follow the same steps within safe mode after hooking up to the other system?

 

W7 Hard drive partition issue

to get rid of that 100 meg windows partition that setup creates for you on a new install on a blank hdd:

- press shift+f10 when on the partition management screen in setup <-- this opens a command prompt
- diskpart <-- start the windows command line partition management tool
- list disk <--- list the installed hdds in this computer for the next step
- select disk 0 <- might have to replace 0 with the number of the correct disk
- clean <-- this will erase all data on the disk you selected one step up- dont use the wrong disk!
- create partition primary <- creates a primary partition taking up all space on the drive, adjust the command if necessary
- exit, exit to exit diskpart and the command prompt
- click refresh in partition manager and select your newly created partition and install to that

 

command prompt will not open in safe mode with command prompt

I am repairing a laptop for a friend and I need to access windows in safe mode and the owner has forgotten the password to the main user. I tried logging on with the administrator profile in safe mode but it is not showing up so I was going to use command prompt in safe mode with command prompt but command prompt will not open when I boot that option. Does anyone have any hints for me to figure this out?
