Windows XP reinstallation does not require reactivation.
If you need to reinstall Windows XP, you usually need to reactivate it. In fact, you only need to back up the Windows\ System32\Wpa.dbl file when you activate it for the first time. After reinstalling Windows XP, you only need to copy the file to Windows\ System32, and you don't need to activate it.
If you don't know whether your Windows XP has been activated, you can check it like this: click "Start → Run" and enter: OOBE/MSOBE/AA. After entering the car, a prompt will pop up to tell you whether the system has been activated.
Windows XP disables driver digital signature warning
Because Windows XP uses a digital signature in the driver, sometimes the driver cannot be installed. You can ignore the digital signature function by opening the control panel → Performance and Maintenance → System, selecting the hardware tab in the pop-up system properties window, clicking the driver signature button, and selecting Ignore or Warning in the pop-up window.
Using Windows 2000 Driver under Windows XP
In many cases, if your hardware or peripherals cannot get driver support from Windows XP, you can download and install drivers from Windows 2000. Although Windows XP may pop up a dialog box to tell you that the installed driver is incorrect (not registered with Microsoft), it can't guarantee availability, but it doesn't actually affect the normal use of hardware. For the sake of safety, it is best to use the system restore function of Windows XP to track every system change and restore it to the desired time point if necessary.
Let the system no longer prompt to insert the system disk (Windows 98)
When modifying the system, if you are often prompted to insert the system installation CD, you might as well copy all the files in the SETUP folder in the system installation CD to a folder on the hard disk (for example, C:\Windows\ Options\Cabs), then open the registry editor and find [HKEY _ local _ machine \ software \ Microsoft \ Windows \ Current Version \ SETUP], edit the string value of SourcePath, and enter a new file path (for example: C:\Windows\Options\Cabs), so that the next time the system needs to install files on the hard disk, it will not be disturbed.
Methods of Removing System Components Unneeded by Windows 2000/XP
The installation of Windows 2000 is overbearing, and everything is installed, so there is no chance to choose the installed components like Windows 98. I can't find anything to delete in Add/Remove Programs. One way to help you delete some components is to open the \WINNT\inf\sysoc.inf file with Notepad, click "Find → Replace", enter:, hide, 7 (all commas here are English commas with no spaces in the middle) in the search box of the pop-up dialog box, and set the "Replace with" box to be empty. And select Replace All, so that all hidden 7s are deleted. Save and exit. Then go to Add/Remove Programs →Windows Add/Remove Components. Now you can double-click the attachments and tools in the list of optional components, and all options can be added or deleted at will.
Similarly, for Windows XP, useless components such as MSN Explorer, MSN Messenger and Microsoft Games can be uninstalled with the above skills.
Add the Windows 2000/XP system switch option to the start menu.
When switching systems under the dual-system environment of Windows 2000 and Windows XP, be sure to keep an eye on the screen and press F8 to select the operation in time. Once you miss it, you have to start all over again, which is very troublesome. In addition, although some users set the time to select multiple startup menu items, there are still more selection processes when switching.
However, if an advanced startup menu is created in the start menu before system switching, you can select the system and mode you need to enter in advance, and then restart the computer to automatically enter the specified system and mode, which is more convenient.
The following operations are only applicable to Windows 2000 and Windows XP dual boot systems. Assume that Windows 2000 is installed in the C:\Windows folder and Windows XP is installed in the D: \ Windows XP folder.
