KMS client activation keys - Windows Server 2022, 2019 and 2016

This is the latest update of the list of windows license keys for key management service activation I publish every few years. Reference the KMS activation post I wrote for Windows 2012 for help installing one of the keys (` slmgr /ipk yourkeyhere` from a command prompt as an administrator)   Windows Server Semi-Annual Channel versions Windows Server, version 1909, version 1903, and version 1809 Windows Server, version 1909, version 1903, and version 1809 Operating system edition KMS Client Setup Key Windows Server Datacenter 6NMRW-2C8FM-D24W7-TQWMY-CWH2D Windows Server Standard N2KJX-J94YW-TQVFB-DG9YT-724CC Windows Server LTSC/LTSB versions Windows Server 2022 Windows Server 2022 Operating system edition KMS Client Setup Key Windows Server 2022 Datacenter WX4NM-KYWYW-QJJR4-XV3QB-6VM33 Windows Server 2022 Standard VDYBN-27WPP-V4HQT-9VMD4-VMK7H Windows Server 2019 Windows Server 2019 Operating system edition KMS Client Setup Key Windo

If E.T. phones home, he won't use entagled qubits

I can recall listening to a radio program some 10-15 years ago. The host of the show believed that it would soon be possible to build a faster-than-light communications system using quantum entangled particles, and interviewed several people from a company who were seeking funding to somehow make that happen. But why not?  There would be tremendous value in some sort of "quantum phone" of entangled particles that allowed for transferring messages faster than the speed of light.  Quantum computers are a real thing now. Quantum key distribution could very well revolutionize public key cryptography. Yet if anything, quantum computing is a misnomer because it understates how fundamental quantum mechanics has been on recent technological innovation. Quantum mechanics has been around for a century now and all modern computers rely to some extent on the principles of quantum mechanics to function. But there will be no quantum phone. Let's start by explaining how the quantum ph

Your spreadsheet is probably wrong

I watched  Rob Eastaway's 2019 for the Royal Institute today. Everything from RI is great and worth checking out, but Eastaway delivered a statistic I hadn't come across before: 90% of all spreadsheets contain errors. Mr Eastaway himself had only come across the statistic from another source, the European Spreadsheet Risks Interest Group (or EuSpRIG for short). This is not a trivial issue. EuSpRIG's website has a "horror stories" section that demonstrates the gravity of errors in the wrong type of spreadsheet. Even if we discard the few stories involving malware embedded in spreadsheets like  the BlackEnergy power plant shutdown  - for many reasons it makes sense to count and study malware separately from unintentional human and formulaic errors - the EuSpRIG lists dozens of separate incidents that involve massive financial losses . Taxes, criminal and medical records are all stored on spreadsheets. Single digit error rates have major repercussions. Claims putti
