Today, I have nothing to do. It took me a few hours to patch XP thoroughly. First, I used the snapshot of Thunder, then I used QQ doctor, 360 security guards and Rising to detect vulnerabilities, and then I tested it several times before patching it. Finally, I used WINDOWS UPDATA to find the last vulnerability patch and made 242 patches. The software installed in the system includes XP system, OFFICE and WMP. The following patches or software are temporarily useless and will not be installed. After such transformation and patching, my system is finally safe under the theory of MS, and MS is really tough. Patches came out one after another. If you install the most primitive XP (that is, you haven't even played SP 1), then if you want to make your system safe, it will be more depressing than installing a system, and it will take longer, and you may not be able to play all day. See if you can find the most primitive system later, and then check the patches to see how many there are.

You can also check for yourself how many patches are installed in your system. If it's not as much as mine, first check whether OFFICE is installed. If you also installed the three softwares I mentioned above, congratulations, you haven't cracked all the loopholes yet. Please continue your repair work. If the difference is not big, then your system is safe in MS's view.
