You can fix the system with 360 and you're good to go.

I'll tell you, hehe, I can finally help people, this problem has been bothering me for days, and I just solved it. In fact, we all think about the problem too hard.

First, I went to "Start" and typed in "Window Defender" and set it to be automatic and on.

Second,You should have used 360 to optimize boot acceleration,Turn off all the programs related to window defender,I was before,Use 360 to optimize boot speed,The result is a one-click optimization,The result is that all the items related to window defender are turned off,And then there is a prompt on boot "Application initialization failed"。

Thirdly, you go to 360 Security Guard, go to "Boot Acceleration", find the disabling history, and enable all the options related to Window Defender.

Fourth, restart the machine, I don't have that problem after I restart.

Fifth, I hope that the people who are in the problem will not always scare people like us who don't understand the computer very well, what a redo system, this is broken, that is broken, if you don't understand, don't mislead the majority of people who have had this problem.

Finally, I hope mine can help you, I used to always look at other people's answers, and today I can finally help others to pull, happy.

Actually, this is fairly simple, and none of the methods I found on the Internet worked. In fact, this is a software conflict problem, just go to Windows Security Center and turn on "Malware Protection". If the prompt is expired, update it, the first time it may fail, and try again.

If you look for "Windows Defender" in the left partition of Security Center, it scans for spyware, and there will be no initialization failure prompt. That's it.

It may be that the service of WD has been terminated, Start Menu > Attachments > Run > Input > Find the service item of Windows Defender, double-click Enable and set the startup type to "Automatic" and then restart it.

It's because you've turned off one of the services, including Ready Boost, Windows Search Indexing, and Windows Defender.

Right-click on the computer, management, service, and let's find it yourself.

Typical system is broken, or a program file is deleted, the system boots up automatically, and the software sends an alarm.

The system is broken. There is a problem with the system disk I bought. It is recommended to buy a new one and reinstall the system.

If the initialization of the computer fails, you can try the following methods to solve the problem:

1. It may be caused by virus Trojan horse, in today's Internet era, in order to get more profits, viruses are commonly used to kidnap applications and system files, and then some security antivirus software kills applications and system files infected by virus Trojans.

2. The application components are missing, and the complete operation of the application needs to be supported by some system files or some LL files, which will also be caused if the application components are incomplete.

3. The problem is easy to occur if the system file is damaged or lost, and the pirated system or ghost version system is very likely to occur.

If not, the only way to do this is to reinstall the system.

Question: Can I restore the backup by myself?

Find a programmer.

In addition, in general, you need to reinstall the system to ask questions

Back up your data and redo your system.

I guess I deleted something that shouldn't be deleted.,Reinstall the system!

Check the boot items. It's more intuitive to use 360, if you're familiar with the computer, then look for the startup items of the registry, including the user subkey and the run key of the machine, the startup item in the program, msconfig can also be seen directly...

It is estimated that a program is automatically running when it is turned on.,But there is an error in running.。。

There is a possibility of a Trojan horse.

You can use the Event Manager to see what's wrong, or disable all startup items first, all of which are caused by bugs in your program.

1) Press F8 immediately after booting or not turning on the phone to press F8 without moving to the advanced option to appear in the release hand, use the up and down keys to select the safe mode enter, enter the safe mode and use the software to kill the Trojan, uninstall everything installed before the accident, restore the system or reinstall the system (if you can enter the safe mode, it means that you have installed something inappropriate, uninstall all the inappropriate things before the accident, and you are hit by the Trojan, use the software to kill the Trojan, if not, restore the system or reinstall the heavy liquid, If you can enter the normal mode, you can also follow the above method in the positive and negative burial mode).

2) If the above methods can't solve the problem, first soft and then hard, reinstall the operating system, don't install software, patches, drivers, etc., and see if there are still problems with booting? If you don't install drivers, patches, and software shortages step by step, don't install anything that doesn't fit it.

Please note: If you restore the system or reinstall it, when installing drivers, patches, software and other things, be sure not to install the things that affect your accident this time, otherwise it will be restored or reinstalled in vain.

3) Whether there is a problem with hardware, such as hard disk, memory, graphics card, motherboard, etc., if it is caused by hardware problems, it is recommended to overhaul it.

The system file was deleted by mistake.

Something is missing in the system!
