Well Microsoft was wrong when Windows 10 is the last version of Windows ever. Thanks to Apple's Mac OS 11 last year, Microsoft decided to roll out Windows 11 anyway to probably compete with Mac OS 11, though this is the replacement to the cancelled Windows 10X which was meant originally for foldable devices and later for the desktop. Also I hope Windows 11 ends the long-time pain of a buggy and mediocre Windows 10. Windows 10 was made to replace a terrible start menu with a cheesy and terrible Metro UI from Windows 8 that only benefited mobile and all-in-one PC users with touchscreens.
So far I know from this:
-- It will have a new start menu with a better user interface, but still not even close to a better UI seen in Mac OS X/11 and Windows 7.
-- It will have a revamped Microsoft Store with support of running some Android apps (thanks to Amazon partnership). Details are sketchy on which Android apps will run on Windows 11. Also hoping the store will be less buggy and can install or remove MS apps with minimal issues.
-- New game features such as AutoHDR, DirectStorage and Xbox Game Pass.
-- Like Windows 10, the upgrade will keep your settings, especially program data settings, and it will be free to upgrade for eligible MS users.
-- The opened windows can be selectively customized for size in addition to maximize or minimize windows so you won't have to modify the size of the window(s) yourself.
-- System requirements only works on a 64-bit PC with UEFI, and you have at least 2 ghz dual-core CPU, 4 GB RAM and 64 GB hard drive space (the 1 GHZ dual-core CPU is BS). Also you need system firmware TPM 2.0 and above for CPUs with at least 8th Gen Intel Core or AMD Ryzen 2nd Gen and above. It's more painful for old tablet and laptop users who may need to upgrade or buy a new mobile device. Such a huge OS may need a much faster PC.
So far I don't know whether this will be improved:
-- A new version of Windows Defender with antivirus, antimalware and a working two-way firewall enabled by default and use less system resources, maybe enough to kill Norton Security, McAfee, AVG and others who love to hog system resources.
-- PC Settings (though most options are in the PC settings, some of the old options from the control panel still exists from there). Otherwise you have to download a tweaker app(s) even to change advanced appearance settings that MS removed recently which no one liked.
Still questionable whether Windows 11 will have this when installed:
-- An app to open a virtual optical drive from ISO and BIN files.
-- An app to open ZIP, RAR, ISO and CAB archives (like 8-Zip), or even create ZIP, 7-zip and others.
-- Powershell (just to install, uninstall or activate MS UWE apps if MS Store still sucks, unless you know coding)
-- MS Dotnet Framework 6.0 with backwards compatibility to 5.0, 4.0 and 3.5.
-- One comprehensive MS Visual C++ Runtime version to work for all old and new games and with future updates. The pain is that almost every game must install that version of Visual C++ Runtime whether if it's x86 or x64.
-- Legacy apps such as MS Solitaire Collection, Photo Viewer and Media Player, otherwise it's to the MS Store or third-party app to download them.
-- Full 16-bit and 32-bit app support on a 64-bit OS regardless of version of Windows, otherwise it's back to third party apps to get to this.
Also questionable but I wouldn't guarantee this, lessons learned from recent buggy Windows 10 versions, especially some issues affecting hardware, software and MS apps. When Windows 10 first came out, there had been a lot of hardware issues and DirectX 12 wasn't enabled for some video cards until a few versions later. All recent Windows 10 versions are buggy, except for Win10 Enterprise LTSC. The other issues to be aware of are spyware rootkits and telemetry.
