It’s been a while since I did these stats, and I don’t think I’ve ever blogged them before, but I was prompted to check this after hearing Microsoft say that Windows 7 has overtaken previous versions worldwide.<\/p>\n
It turns out that even though there hasn’t been any particular institutional drive towards Windows 7, thanks to the efforts of pro-active staff across the University, it does now significantly outnumber all other operating systems in our Active Directory combined! In the last 3 months, the breakdown of computers is…<\/p>\n
Windows 7: 7155
\nEverything else: 5385<\/p>\n
There are an unknown number of machines that aren’t connected to Active Directory, but the spread of those won’t affect this a great deal.<\/p>\n
Another interesting stat that I heard recently came from Dell. They now predict that 50% of all server workloads are virtualised. Thats probably about true here – I’ll see if I can get those stats later.<\/p>\n
Incidentally, the breakdown of Windows servers in our AD sees roughly equal numbers of Server 2008 R2 and Server 2003 (just over 200 of each), and just over a hundred running Server 2008.<\/p>\n
If anyone is interested in grabbing these stats in their own organisation (or OU), then it’s just a simple bit of PowerShell using the Quest AD cmdlets<\/a>…<\/p>\n \n$computerObjects = Get-QADComputer ` (That’s just 3 lines of code, but it could be fewer.
