Ok so this issue has been happening for about a month now and it's getting really annoying. Now my system is running Windows XP Professional Service Pack 3. I was trying to download windows malicious software in hopes of resolving this issue. It says it's not compatible with my system and it says I'm running Windows 2000 32-Bit. Applications for me have been failing for the past month. For example, Google Chrome says "Chrome requires Windows XP or higher for it to work properly, some tools may not work properly" or something along those lines. Some games aren't working for me that well. For example, Wizard101 won't even let me open it, even though I've redone loaded it a bunch of times, it ran perfect a few months ago. As well as RuneScape client. This doesn't open as well even though it ran perfect a few months ago. At one point Google Chrome stopped working completely. Every time I tried to open it it would give me a error message. I don't get why this is happening, I uninstalled a bunch of software as well as did a disk defragmenting. My pc is 6 years old and I will list the specs if needed to. Every application thinks I'm running Windows 2000 and some of them don't work. Also if this is relevant I disabled Windows Firewall because it kept crashing games. Please help me.
