Keep in mine I think a Windows XP machine may have hardware limits. Someone in my family works on computers and told me the Windows XP only works properly with a maximum of 4GB of RAM and maybe only a 2TB harddrive
PC gaming is not like console gaming it takes a lot more knowledge to operate then any standard tv video game console does
I am not sure so someone please correct me if I'm not telling truth
Windows XP Pro 32bit, sort of, has those hardware limits. Being a 32bit operating system, it uses 32bit addressing, and thus has maximum values that it can recognise for things like RAM and partition sizes that include bootable volumes. For RAM, the maximum addressable size is ~4.2 GB. As with all Windows computers, that number is then lowered by hardware addressed memory, then shared memory and then operating system overhead. The numbers shown in the "available" section in Computer Properties can be deceiving because it is not reflective of the true amount of memory that is free. There are methods to increase addressable memory, notably PAE, but this should only be used in certain situations.
For the disk size, the maximum amount of addressable space on a 32bit OS with an MBR disk is 2.2 TB. however it is theoretically possible to get at least 4 TB on MBR using 2 partitions. I say theoretically because, while this has been proven on Windows 7 32bit, there haven't been any inroads or continuing work on getting Windows XP to view the partitions properly. It is known that it would require UNIATA at least, but it may also require hardware modification such as the sector translators found in some USB hard disk enclosures. Windows XP 32bit cannot read contents of a GPT disk of any size except for those that are going through sector translators. I haven't looked into research done on this to see if anyone got it to work with just software.
Windows XP 64bit, not known for being a gaming OS, particularly because it lacks the 16-bit compatibility as the 32-bit OS... which means that a lot of early XP games cannot run or cannot install because the subsystem is missing. It does not have the 4 GB addressable memory limit. It cannot have a bootable volume on a GPT disk, the disk the OS is on must be MBR. It can use a GPT disk (volume sizes larger than 2.2 TB) as data only. I have not been involved in or looked into any research for XP x64.
As for original question, the only Windows XP computer that I currently use is my second notebook. For me, computers have a purpose for use and that Windows XP notebook is designed specifically for accessing TLS 1.0 and 1.1 interfaces. It is not fully set up yet, I am in the process of installing RAM overlay and still need to figure out which firewall I want to put on it.
