Have you automatically updated Microsoft's patches?

In safe mode, using system restore operation can completely solve your problem. I have encountered it myself. , I solved it with this method.

Remember, don’t update automatically in the future. You can download patches from Microsoft’s website.

Windows XP SP2 Internet Activation Program< /p>

The implementation principle is the same as what I mentioned below, which is nothing more than replacing the corresponding files of pirated Windows XP with the original files of VOL.

You can purchase a D version of XP installation CD, which generally does not require activation!

Microsoft is committed to protecting intellectual property and fighting software piracy. Everyone in the economic chain -- not just software manufacturers -- is harmed by piracy, including retailers, suppliers, and you, the end user. Genuine Microsoft software is guaranteed to be high quality and harmless. Eliminate pirated software.

Windows XP retail products include software-based product activation technology, which means you need to activate your Windows XP backup before it can be used. Some newly purchased PCs that already have Windows XP pre-installed also require activation. If your organization licenses Windows XP through a Microsoft Volume Licensing Agreement program, such as Open licensing and Select licensing, you do not need to activate those Windows XP licenses.

Microsoft Product Activation is an anti-piracy technology that verifies that software products are properly licensed. Its purpose is to reduce piracy due to inadvertent copying. Activation also helps protect the hard drive from being copied. Activation is quick, easy, and unobtrusive, and it protects your privacy.

Product activation works by verifying that a software program product key has been used on more personal computers than the software's licensed user. In order to install the software, you must use a product key, which is converted into an ID number required for installation. You can provide an installation ID number to Microsoft using the Activation Wizard, or you can provide the number over a secure Internet transmission or by using a telephone call. A confirmation ID will be sent back to your computer for activation of your product.

The installation ID number consists of an encrypted form of the product ID and a hardware hash or checksum. This does not include or require personally identifiable data. The confirmation ID is simply an unlock code for Windows XP installed on a specific PC.

If you examine a piece of your computer's hardware after replacing the actual code, you may find that it looks like a different PC. You must reactivate Windows XP. If this happens, you can reactivate the software by calling the number shown on the activation screen.

If you have not activated Windows XP, your computer will remind you each time you log in and at regular intervals during normal use until the 30-day activation grace period ends. If you have not activated Windows XP within this period, you will need to activate it now to continue using it.
