How to deal with Windows 11 cannot turn on Windows Defender | Perfect solution
After I upgraded from windows 10 to 11, Windows Defender
Everyone knows that the Windows 11 system has a built-in security protection software, Windows defender. This software can be said to be very easy to use, but recently some win11 users reported that Windows 11 windows defender cannot be turned on, so what should I do? Don't worry, how to integrate an article about how to solve the problem that Windows 11 windows defender cannot be turned on, please read down.
Specific steps are as follows:
1. Press "Win+R" to open the run window, enter the "services.msc" command and press Enter.
2. Use the "tasklist /svc" command in the command prompt window to query the actual corresponding application of the Windows Defender service.
3. If you can see after the query, the application path corresponding to the service is "C:\Program Files\Windows Defender\MsMpEng.exe", and the service cannot be started by clicking Start, or it will display the operation solution after clicking.
If it still does not work properly and the error persists, please try the following methods:
1. In a computer with normal "Windows Defender Service" service item, use the "tasklist /svc" command at the command prompt to view the corresponding items of services and programs as follows, the service PID process number is 2664, which corresponds to " MsMpEng.exe" file.
2. However, after finding the corresponding application, you can find that it has not been tampered with after comparing the certificate with the normal "MsMpEng.exe" file.
3. After confirming that the original file of Windows Defender is OK, such an error message is given, and the service cannot be started through the normal service management page. This problem is likely to be a bug in the current Windows 10 operating system. To resolve this issue, right-click the Start Button, select Command Prompt (Admin), enter the following command, and press Enter, "sc start WinDefend Enable".
4. At this time, let's take a look at the Windows Defender that prompted the error before, and it should be able to open normally.
