The Windows wait cursor, informally the Blue circle of death (known as the hourglass cursor until Windows Vista) is a throbber that indicates that an application is busy performing an operation. It can be accompanied by an arrow if the operation is being performed in the background. The wait cursor can display on programs using the Windows API.
In computer science and software engineering, busy-waiting, busy-looping or spinning is a technique in which a process repeatedly checks to see if a condition is true, such as whether keyboard input or a lock is available. Spinning can also be used to generate an arbitrary time delay, a technique that was necessary on systems that lacked a ...

[7] Most operating systems (including Solaris, Mac OS X and FreeBSD) use a hybrid approach called "adaptive mutex". The idea is to use a spinlock when trying to access a resource locked by a currently-running thread, but to sleep if the thread is not currently running. (The latter is always the case on single-processor systems.) [8]

Problems with the virtual memory system—such as slow paging caused by a spun-down hard disk or disk read-errors—will cause the wait cursor to appear across multiple applications, until the hard disk and virtual memory system recover. Instruments is an application that comes with the Mac OS X Developer Tools. Along with its other functions ...
BSoDs in the Windows NT family initially used the 80×50 text mode with a 720×400 screen resolution, but changed to use the 640×480 screen resolution starting with Windows 2000 up to 7. Windows 2000 used its built-in kernel mode font, Windows XP, Vista, and 7 use the Lucida Console font, and Windows 8 and Windows Server 2012 used the Segoe UI ...
In Windows, bug checks are only supported by the Windows NT kernel. The corresponding system routine in Windows 9x, named SHELL_SYSMODAL_Message, does not halt the system like bug checks do. Instead, it displays the infamous "blue screen of death" (BSoD) and allows the user to attempt to continue. The Windows DDK and the WinDbg documentation ...
