Windows

Windows is a line of operating system products from a company known as Microsoft. These are the primary operating systems used when Microsoft Sam reacts to errors. These errors do not come from Microsoft themselves, but they are mostly written by Mr. B, the owner of the ClassicSamVideos channel (although there can be other sources of errors), using a generator created by Barra. On his main computer (and now on the computer in Windows Private Island), Sam can also freely upgrade to any other Windows version because of Mr. B’s changes, but as long as the upgrade-downgrade machine is working, it seems. For example, Sam once wanted to go to Windows 98, but the machine was broken right then. Other times, the computer can outright force him to downgrade or upgrade to other operating systems.
The Operating Systems may appear sentient, but this is merely just an illusion.
== Windows XP ==
Microsoft Sam primarily uses Windows XP when reading errors. There is currently no background image attached to this OS due to the changes, but the errors are shown nonetheless. These window messages have blue outlines for the title, with light yellow space for the message space and the option buttons, though the option buttons can also be white with a blue-ish outline. Note that when Microsoft Sam supposedly turns into a zombie, the entire window is tinted green because errors can be manipulated like that. It is later revealed that Windows XP is apparently scared of zombies. The reason why XP didn't run away then is because Sam didn't actually turn into one; he was faking it.
Windows XP can be found in Sam's house, and recently, in Windows Private Island due to the Orb of Light, the computer having the same upgrades that Mr. B did to the computer back in the CSV House. The Afterlife has at least one spare computer, which also has Windows XP on it, and has received similar changes.
== Windows 11 ==
This is one of Sam's least favorite operating systems, and he never plans to use it. However, when he turns into a zombie because of Dr. Zomboss (for real this time), Windows XP gets scared and upgrades to this OS. However, even as a zombie, Sam dislikes this system, because he hears that Microsoft Flight Simulator is the only game they have. But because of the upgrade-downgrade machine being broke, he reluctantly reads errors in it. The errors so far don't seem to be any different than in XP, but there's more corporate jokes in it. The messages also are white, instead of opting to have different colors like XP.
The spare computer in the Retcon Room also has Windows 11, and it seems to be the same deal as Sam's old computer in the Private Island, except with the changes seen before.
== Windows 9x ==
When Sam goes to Windows Private Island, he was forced to use Windows 95 since that's all that could be afforded on this island after getting that mansion. Sam does not seem to have a strong opinion for or against this OS. 
The errors are more of the same from XP. Funnily enough, the computer is capable of having a 3 exabyte hard drive. The outline of the messages are blue, like in XP, except in a darker shade, and with gray space for the message and option buttons.
