Windows 11 is the latest major release of the Windows NT operating system and the successor of Windows 10. Some features of the operating system were removed in comparison to Windows 10, and further changes in older features have occurred within subsequent feature updates to Windows 11. Following is a list of these.
JIT causes a slight to noticeable delay in the initial execution of an application, due to the time taken to load and compile the input code. Sometimes this delay is called "startup time delay" or "warm-up time". In general, the more optimization JIT performs, the better the code it will generate, but the initial delay will also increase.
In computing, copy-and-patch compilation is a simple compiler technique intended for just-in-time compilation (JIT compilation) that uses pattern matching to match pre-generated templates to parts of an abstract syntax tree (AST) or bytecode stream, and emit corresponding pre-written machine code fragments that are then patched to insert memory addresses, register addresses, constants and ...
Windows 11 SE was announced on November 9, 2021, as an edition exclusively for low-end devices sold in the education market; it is intended as a successor to Windows 10 S, and also competes primarily with ChromeOS. It is designed to be managed via Microsoft Intune. Based on feedback from educators, Windows 11 SE has multiple UI differences and ...
Windows 11 Search adds the ability to search for documents and photos using descriptive phrases instead of just file names. [14] Super Resolution: photographs may now be enhanced up to 8x without sacrificing quality using AI upscaling, which works faster on Copilot+ PCs. [15] Windows Recall (preview) which lets users find content they have ...
The Surface Laptop Studio will be powered by the new Windows 11 operating system with a 30-day trial of Microsoft 365. Consumer models will get the Home edition and the business models will get the Pro edition of the operating system. The device also supports Windows Hello login using biometric facial recognition.

JIT then will transform bytecode to native x86 code like: 0: b8 44 33 22 11 mov $0x11223344, %eax mov eax, 0x11223344 5: 35 11 22 33 44 xor $0x44332211, %eax xor eax, 0x44332211 a: 35 11 22 33 44 xor $0x44332211, %eax xor eax, 0x44332211. The attacker then uses a suitable bug to redirect code execution into the newly generated code.
Further, JIT compilers can speculatively optimize hot code by making assumptions on the code. The generated code can be deoptimized if a speculative assumption later proves wrong. Such operation slows the performance of the running software until code is optimized again by adaptive optimization .
