There are several ways to update the Service Pack. Operating system updates, as a rule, should be done automatically (using the Internet), but sometimes, especially when a "modified" version is installed, you have to look for an update on specialized sites.
Instructions
Step 1
Automatic updates are easy enough. And if for some reason it is not turned on, then you can activate it like this: Start - Control Panel - Automatic Updates. But if your version of Windows is not a licensed, so to speak, "clean" version, but it contains any modification (for overclocking, optimization, etc.), then it is better not to update as standard, since problems may arise in the operation of the system or by chance, the so-called. "Activation", "authentication" or something like that.
Step 2
If the standard update (via the Internet) did not work and system errors appeared, then you can try to do a system restore. It is done like this: Start - All Programs - Accessories - System Tools - System Restore. If automatic updating has not been disabled, then you should urgently disable it. And it would not hurt to do an analysis using the CCleaner program, so that unnecessary files from the system were eliminated.
Step 3
You can try to download the latest Service Pack from the official Microsoft website (www.microsoft.com). And install through the standard installer. Possibly what to do system debugging
Step 4
When the options from the official sites are completely inappropriate, the point is that the computer has a modified or user-optimized version of Windows XP. And updates with it do not work correctly for this reason. Such versions should be updated using separate portals or sites dedicated to the modification (and such sites should be thoroughly checked, including looking at user reviews). Searching for such an update is most likely best done through search engines.
