Experience and skills of reinstalling Windows XP system

Microsoft has added an activation function to XP (the so-called activation means that you must contact Microsoft via the network or phone within 30 days after installing XP to activate your system, otherwise you can only use it for 30 days and you will not be able to enter. The system is up. You can only enter in safe mode. This is a means of Microsoft's anti-piracy.)

How to reinstall the xp system on the official website of the installation bar first, search and download the installation bar system to reinstall the software, and plug the USB flash drive into the USB socket of the computer. Turn off the anti-virus software and select the production system to enter. Then click to start production. Check the xp system version you need to install and click to start production.

This article will introduce the installation steps of Windows XP system to help users better understand the system installation process. Enter the BIOS setting interface to start the computer. When the Press Del to Enter BIOS Setup prompt is displayed on the screen, press the Del key on the keyboard to enter the motherboard BIOS setting interface.

Prepare the installation CD of Windows XP Professional Simplified Chinese version and check whether the optical drive supports self-starting.If possible, scan all hard disks with the disk scanner to check for hard disk errors and fix them before running the installer, otherwise it will be troublesome to check for hard disk errors when the installer is running.

Prepare a Windows XP CD, write down the installation serial number of the CD on paper, and then you can start installing the system. To use the CD-ROM installation, you must first set the computer in the BIOS to start from the CD-ROM, that is, when the computer starts, press the Del key in the self-test. After the self-test, the BIOS interface will be displayed.

Use the driver backup tool (e.g. Driver Genie 2004 V9 Beta.exe) to back up all drivers under the original Windows XP to the hard disk (e.g. F: Drive).It's best to write down the models and manufacturers of main hardware such as motherboards, network cards, graphics cards, etc., and download drivers in advance for backup.

Briefly describe the experience and lessons learned in the development of public security information system.

. Achievements and shortcomings. This is the main content of the summary. The purpose of summary is to affirm the achievements and find out the shortcomings. What are the achievements, how big they are, in what aspects, and how they are achieved; how many shortcomings, in what aspects, and how they are produced, should be clearly written. 3. Experience and lessons.

Clarify the role positioning and main functions of public security organs in national functions. The reform of the major ministry system must first clarify the relationship between the powers and responsibilities of public security organs and other government departments, and clarify the role positioning and main functions of public security organs in state functions.The functions of public security organs are realized through the power of the police, so it is first necessary to distinguish between the power of the police and the general administrative power.

[#Work Summary#Introduction] In summary, we can raise the scattered and superficial emotional understanding to a systematic and profound rational understanding, so as to draw scientific conclusions, so as to carry forward achievements, overcome shortcomings, learn lessons, and make the future work less detours and produce more results.

We should pay attention not only to the accumulation of work experience, but also to the improvement of work level. We should adhere to the principle of "one and reverse three" in our work, constantly summarize lessons learned, exercise the police force, and cultivate comprehensive quality.

Improve the comprehensive utilization of public security information resources, and further promote high-end applications such as public security intelligence information system. Build a public security information application pattern of whole police collection, whole police application and whole police sharing.Realize team building, internal management, law enforcement quality and other informatization.

Archive data and historical decision-making experience. The changes in criminal crimes in each period and the corresponding situation policies and work materials, the statistics and analysis of relevant data of public security business work, and the experience summary of relevant decisions in history.

Reinstallation system summary of two years of computer repair experience

1. Find a tool disk (the current system disk comes with various tools) and read the interface of the CD.

2. First of all, I would like to introduce a simple and practical reinstallation method, which is the "backup and restoration method". Nowadays, many computers will install a one-click GHOST tool at the beginning of installation, the purpose of which is to make the computer appear.The problem needs to be used when reinstalling the system. Since it is a "backup and restoration method", we naturally need to back up first.

3. Reinstall the computer system on the USB disk. If your computer can no longer start up normally, first go to your friend's house to find a computer that can access the Internet normally, and download the computer boot program from the installation bar one-click reinstall system tool to make a USB disk boot disk.

linux common system management experience talk

1. If the prompt of "Repair filesystem" appears, try to use e2fsck /dev/hdx to repair After the complex file system is successfully started, the ext2 file system is converted to ext3 by creating a journaling inode log.

2. The working principle of the kill command is to send a system operation signal and the process identification number of a program to the kernel of the Linux system, and then the system kernel can operate on the process specified by the process identification number. For example, in the top command, we see that the system is running many processes, and sometimes we need to use kill to stop certain processes to improve system resources.

3. Linux virtual memory implementation mechanism The implementation of Linux virtual memory requires the support of six mechanisms: address mapping mechanism, memory allocation recovery mechanism, cache and refresh mechanism, request page mechanism, switch system, memory sharing mechanism.

4. The system administrator first puts the Linux installation disk into the optical drive of the Windwos client.Use the remote management of the Windows operating system to effectively create RedHat boot disk files.

Some experience in the design of the water system in the building

Storing adjustment: The raw water regulation pool should be obtained according to the hourly change curve of the raw water volume and treatment volume, and the middle water storage pool should change from time to time according to the treatment volume and the amount of water used in the middle water. Calculate the curve. The change curve of raw water and the use curve of medium water can be formulated according to the nature and usage of drainage buildings and refer to the data of similar buildings in the same region.

Therefore, when designing a toilet water supply system, we should fully consider the disadvantages of this method, set up a separate toilet flushing pipeline, realize the separation of the drinking water system from the toilet water supply system, and ensure the water supply safety of the water supply system.4 Closed pipe well drainage design.

Outdoor water supply system In ultra-high-rise buildings, the design of outdoor green water supply system is also very important. Under the background of the state's proposed ecological construction, the outdoor greening water supply system of ultra-high-rise buildings usually adopts a green and environmentally friendly rainwater recycling system.
