Analyze the management of Windows operating system

        Many individual users now use Windows XP, but do you know? There are a series of tools in the Windows operating system. Many of these tools are used to maintain the system. In this article, I will introduce how to use these tools. At the same time, the author will start from four aspects of system maintenance, management performance, system security and disk space management to introduce how to more effectively and better maintain our Windows system.

The first part, the maintenance of the operating system

First, the automatic implementation of Windows system update

For users of Windows XP system, Microsoft provides an automatic update service to ensure your The operating system is automatically updated at any time. Windows XP can query Windows Update for the latest update service when the system logs in and connect to the Internet, and determine the update project for the local computer. Then, when you use the operating system, "automatic update" downloads the patch to the background. Local hard drive.

To set the "Automatic Update" feature to on or off, follow these steps:

1. Click --> Start--> Control Panel --> Automatic Updates.

Note: There is also a method here, you can right click on "My Computer" to select "Properties", or you can set the "Auto Update" function.

2. On the "Automatic Updates" tab, click on the setting you want (Figure 1).

Figure 1

Note: If you think that you will install the update package downloaded from the Windows Update website manually, then you can choose to turn off the "automatic update" function.

Second, the damage event log file

Event Viewer is one of the management tools included in the Windows Management Console, it is used on your computer for related programs, security features and The log information generated by system events is maintained. You can use the Event Viewer to browse and manage event logs, collect information about software and hardware failures, or monitor Windows security events.

If the Event Viewer reports to you that one or more log files have been corrupted during system startup, you can take the following remedies:

1. Disable the event log service.

2. Restart Windows XP.

3. Delete the corrupted log files from the %SystemRoot%System32Config directory (or other locations) -- Appevent.evt, Secevent.evt, and/or Sysevent.evt. All of your existing event data will be lost, but new log files will be created and restarted to collect new event data when the event log service is restarted.

4. Re-enable the event log service and start it.

5. If the event log service fails to start successfully, restart Windows XP.

You will not be able to delete or rename log files while the event log service is running.

III. Protecting files during power outages

If a power outage occurs while the computer is in a waiting state, all information in the memory will be lost. If you do not save the document at this time, you will lose the edited content. However, with an uninterruptible power supply (UPS), you can prevent data loss during power outages.

Although the power outage may continue until the UPS battery is exhausted, you can prevent data loss from happening; even if your computer happens to be in a waiting state and you are no longer nearby when the power is off, The edited data information will still not be lost. To implement the above assumptions, make the following settings in "Power Management Options":

Activate the sleep function. (Click the -->>Start-->Control Panel--> Power Options and select "Enable Hibernate" on the Hibernate tab (Figure 2).

Figure 2

Set the time required for the computer to wait before switching the system to sleep. The time set here should not exceed the battery running time. (On the "Power Scheme" tab, set "Battery Operation Status". The system sleep wait time.)

Fourth, the shortcut to call the power management options

The use of menu navigation to call the "Control Panel" option is more cumbersome. Here is provided a system Quickly invoke the "Power Management Options" shortcut when the desktop portion is visible.

Right-click on the system desktop blank area and select the PropertIEs command on the shortcut menu that pops up.

In the Display PropertIEs dialog box, select the Screen Save tab and click Power.

If you are a command-line loyal follower There is a more kind here. The method of Czech. Please enter Powercfg.cpl directly in the command line mode.

V. Determine the size of free space on the disk

Checking this is very simple, we can use two ways to view The size of the disk space.

A: Double-click to open my computer, click on your system disk, and then click on the information on the left to see the remaining space on the disk.

B: Also You can right-click the disk and click Properties to see the amount of free disk space and other disk properties.

VI. Cleanup Desktop Wizard

The Cleanup Desktop Wizard is a Windows XP system. Very useful. But using the Windows XP Desktop Cleanup Wizard takes more time and effort than cleaning the desktop manually.

Method 1: If you are using Windows XP, maybe Try the following desktop cleanup method: Right click on the blank space of the desktop and select "Properties" * "Desktop" * "Customize Desktop". In the "Desktop Cleanup" project, make sure "Run Desktop Cleanup Wizard every 60 days" is selected. After booting, if Windows finds that some shortcuts on the desktop have not been used during this time, a prompt dialog will be given. If you want to activate this wizard, click the "Clean Desktop Now" button. If some Desktop shortcuts are rarely used, but you need to save them on your desktop, and the wizard will give you options to check which specific desktop shortcuts are checked during regular checks. Desktop Cleanup Wizard Save those icons that have been cleaned up in a desktop folder called "Unused desktop shortcut icons" (Windows systems will automatically create them when needed).

Method 2: The Windows system includes all the tools that need to customize the automatic reminder mechanism for desktop cleaning. By cleaning the desktop in this way, you can easily find shortcut icons, files and folders that have not been used recently. At the same time, you can also set the time interval for the cleaning program to work. This method has a good performance in Windows Me/2000/XP, and it can be done in Windows 9x.

Note: Users running this program on Windows 9x systems cannot get clear prompts.

VII. System Backup

Using the "Backup" Backup Utility will help you create a copy of your hard drive information. In case the original data on the hard disk is accidentally deleted or overwritten, or is inaccessible due to a hard disk failure, you can use the copy to recover lost or corrupted data. To make a backup, there are some very simple and convenient methods, using the backup function that comes with the system, click "Start", point to "All Programs" - "Accessories" - "System Tools", and then click "Backup" (Figure 3).

Figure 3

The Removable Storage Service must be started for "Backup" to work properly.

You can also use the Recovery Wizard in the Backup Utility to help you repair your system.

For information on using backups, click the Help menu in Backup.

Eight. Maintaining the system registry

We know that the windows registry is the lowest level setting to control the system startup and operation. The files are system.dat and user.dat under the windows installation path. These two files do not display the system settings in plain text, and ordinary users cannot modify them at all. And we know that if you install/uninstall applications frequently, the settings added by these applications in the system registry are usually not completely deleted. After a long time, the registry will become very large and the system will run faster. affected. At present, there are many automatic debugging, compression and optimization tools for the Windows registry. It can be said that the Windows doctor provided by Norton utilitIEs is the best, it not only provides a powerful automatic detection of system registry error settings. Features, but also provides automatic repair. With this tool, even if you don't know anything about the system registry, you can do it very easily, because you can complete the system error repair by simply clicking the "next" button in the program interface with the mouse.

IX. Backing up the system registry frequently

Backing up the system registry is the easiest and most effective way to ensure that the windows system can run stably, maintain the system, and restore the system. We know that the system registry information is saved in the windows folder, and its file names are system.dat and user.dat. These two files have implicit and system properties. Now you need to do a backup of these two files. You can use regedit's export function to copy these two files directly to the backup file path. When the system fails, you will The backup file is directed to the Windows path and the source file can be overwritten to restore the system.

X. Detecting and repairing disk errors

In addition to defragmenting disks, Windows has a program that can fix hard disk errors. Of course, if the disk is really physically damaged, then even the best software can not repair it, but it can read the information in the damaged part of the disk and then write it to other places on the disk, so that you can be timely Save useful information to other places to avoid loss, and if it is lost due to abnormal shutdown, it will need to be repaired. Let's see how to use it! Open "System Tools" in "Accessories" and select "Disk Scanner". The ScanDisk window appears on the screen.

"Scan type" is the way to specify the scan. Generally, just select "Standard" and only detect errors in files and folders. This is faster; if you think the hard disk is not working properly, doubt Where there is damage, then you can choose "complete", including "standard" detection and disk surface inspection.

"Automatically fix errors" is to specify whether to automatically fix when a disk error is found.

After selecting the drive, click the "Start" button to start scanning the disk.

The second part, management operating system performance

First, change the size of the virtual memory page file

For different computers The size of the page file is different. Regarding the page file size setting, there are two widely spread "formulas", "physical memory X2.5" or "physical memory X1.5". These two calculation methods are simple, but not applicable to all computers. The most accurate way to set the page file size is to look at the page file size that the computer actually uses in normal operation.

With the built-in logging function of Windows XP, you can monitor the size of the page file normally used by your computer for the most accurate settings. The specific steps are as follows.

Right click on "My Computer", select "Properties -> Advanced", click the "Settings" button under "Performance", then select the "Advanced" page, click "Virtual"
