Which master helps the rookie Thank you in advance

Ghost clears all the extra startup items that I haven't used.

The startup item is the self-starting program when the computer is turned on.

More will make your computer boot up slower!

And because of the large number of temporary resources, sometimes it will crash The advantage is that if you clear it, the computer will be faster! The downside! It's more troublesome, for example, if you disable the antivirus software from starting automatically, you need to manually open it every time, isn't it very troublesome?

ghost is not the same thing as knowing the startup items on your computer.

ghost is simply able to restore the image. Make a system image. and engraved.

Clear startup items in. Start Menu - Run - msconfig - Start.

If you don't turn off all the things that start the item.

Because anything is turned off in the startup item, it will not affect the normal operation of the system.

And it's a lot faster when it's turned off.

Disable them all, and the advantage is that the computer starts up quickly. The disadvantage is that the real-time monitoring of the antivirus software is disabled, which is easy to poison.

In the start, click to run, enter msconfig, and disable all the things in the startup, and it's OK.

Generally speaking, it depends on what boot option you are clearing, if it is for the system, there will be a problem if it is cleared, if it is nothing else, it can also speed up the boot of your computer.

Selectively clear, if you don't understand it, don't care about it.

Boundless falling trees and Xiao Xiao, endless Yangtze River rolling.

The water of the Yellow River came up from the sky, rushed to the sea and never returned.

The lotus leaves are infinitely green, and the lotus flowers are different red.

There is a confidant in the sea, and the end of the world is like a neighbor.

Dear....If my back imitation posture volt answer is helpful to you, I hope or praise! Thank you.

This situation is normal because:

1.You don't even feel like it's time to burn your eyebrows.

2.You don't think the results of the exam are important enough to you, or you are going to be lucky.

You have to find a point for you to learn.

1.Otherwise, you will come to review frantically a few days in advance, because at that time you feel that you will really hang up if you don't review again, which is a bit risky for freshman year.

2.You have to set a goal, don't make what you're going to prepare specifically for the exam, you have to learn it well instead of learning it, combine the course with your interests, you use it as a skill, the goal is to understand something, you will do the post-class questions, etc., it will play some positive role in you.

Of course, the most important thing is to know what you really want, do what you really love, and complete what you really want to accomplish to calm your mind. For example, if you want to set a goal to be excellent, then if you are serious, you will spare no effort to prepare for each exam. If your goal is to relax in college, it is almost impossible to calm down and study.

This is distraction, adolescent syndrome. It's been a long time, and I can't calm down now.

Solution: Let the profit of the production of the xth grade of the product be y, and the profit of the xth grade of the product is 6 + 2 (x 1) yuan, and the number of products produced is 60 4 (x 1)] pieces, y = [6 + 2 (x 1)] [60 4 (x 1)].

y=（2x+4）（64﹣4x）=﹣8x2+112x+256=﹣8（x﹣7）2+648，x∈[1，10]，x∈n+．

When x=7, ymax=648

A: The production of 7th grade products is the most profitable
