This is what Microsoft hates. The system provides many practical functions, but it is not put in a conspicuous place for everyone to use. On the contrary, it has given many rogue manufacturers a living space to thrive. Everyone remembers the functions to be introduced. In the future, whether you buy a computer or find someone to repair it, you don't need to prepare tools in advance.
Let's talk about how to check the system health. Win+R only needs to enter one command:
Performance monitoring/reporting
Wait 1 minute to give Windows time to collect information and analyze it.
Microsoft will give a complete report of the current system, including software configuration, hardware configuration, CPU, network traffic, disk performance, memory information and so on. If there are some problems with your computer, they will be marked in a conspicuous way in front, and the causes and solutions of the problems will be given. It must be right for everyone to follow the official instructions.
what did you say ? /Excuse me? There is no problem with normal system application and service detection, but Windows still frequently reports errors or jams. This problem was encountered before Bian Xiao, and a command prompt solution was provided. How to play CMD well was explained in detail in yesterday's "Remember these tricks and you will become an old driver of CMD". After starting in administrator mode, just enter.
sfc /scannow
Just wait for the result. What if you really find the problem? If you use the tutorial "Using sfc /scannow command to repair system files under Windows", everything will be fine.
Make sure there is nothing wrong with the system, but the computer always feels wrong from time to time. Maybe there are some hidden diseases in your memory and hard disk. Memory can be said to be the hardest hit area of computers, and many computer problems are related to memory. A slight problem with memory may lead to unstable system operation, the most common manifestation is blue screen, automatic restart, or even failure to boot. If you can't start the machine, it is easy to solve. Usually just pull it out, clean it up and put it back. If your computer is unstable recently, you often restart the blue screen for no reason, and you don't know whether it is caused by memory chips, go directly to the "Control Panel-Management Tools" to find Windows memory diagnosis.
In the pop-up window, click "Restart immediately and check the problem", and the computer will enter the automatic detection stage after restarting.
In the first stage, if "No problem detected" is displayed, the memory is normal. If no problem is found in the second stage, which proves that there is no problem with the memory, then move on to the next topic!
There are many ways to check the disk. Click the right mouse button on the drive letter and select "Properties-Tools" to start checking the disk for errors.
In addition, CMD has a more powerful way, using CHKDSK X:/F(X stands for drive letter) to check errors from the bottom and start the repair process. Windows can't solve it, just back up the data and prepare money to buy a new one!
After such a set of self-contained tools detection and repair process, as long as it is not Windows blue and can't be turned on, minor problems can basically be solved, which is better than those third-party tools, right? Oh, for notebook/tablet users, Master Lu and other software also have plug-ins for battery cycle detection. If you have such a demand, you can make a small series.
In administrator mode, enter the following command in CMD
power CFG/battery report/output C:attery _ report . html
A complete battery usage report will be generated directly under drive C.
After double-clicking, the report will be opened with the default browser, and the basic information of the battery will be displayed, including the battery design capacity, Wally capacity, charging cycle, the change curve of battery usage in the last three days, and the expected change of battery life. The data you see here is more accurate than the data on the battery icon in the taskbar. Children's shoes that want to buy a notebook can also use this trick to test whether the machine is brand new. In retrospect, Bian Xiao survived in Zhongguancun Computer City by these things.
