From Windows Vista effectively dead as Windows Server 2008 support finally ends (Usama Jawad for Neowin. January 15, 2026):

Windows Server 2008 was supported via the Premium Assurance program until January 13, 2026. Although this support program no longer exists, volume licensing enterprise customers were grandfathered into the Extended Security Updates (ESU) program, which finally expired a couple of days ago for this particular SKU.

What does the end of the last official support channel for Windows Server 2008 have to do with Windows Vista? I quote again from the article:

he SKU was built on the Windows Vista/Longhorn codebase, which is why it was internally called “Windows Server Codename “Longhorn”.

While Windows Server 2008 is not Vista, it was apparently built on the Vista codebase (although Neowin notes Windows Server 2008 R2 was built on Windows 7). Thus, in a sense, I suppose this is the true, official end of Windows Vista. While I never used Windows Server 2008 (or any flavor of Windows Server for that matter), I used a Windows Vista PC as my primary computer for a couple of years in the 2009-11 area, and I believe I first stumbled upon the Insani al|together visual novel translations on my Vista computer. While I know Vista was not popular, I can report that I do not recall having any problems with it or using it much differently than I had been using XP. Note that I did have the 64-bit version of Vista.
