Contexts 3 Radically simpler & faster window switcher Switch between application windows effortlessly — with Fast Search, a better Command-Tab, a Sidebar or even a quick gesture. Includes fantastic features for multiple spaces & multiple displays. The ability to do context switching is an essential component for any multitasking OS. The same type of things that cause context switching in Linux would cause context switching in Windows as well. All a high thread count means is that the CPU will be forced to switch contexts more often to fulfill the processing requirements of the scheduler. Android version updated to 3.7.07.6; macOS version updated to 4.3.1.200243; Windows version updated to 4.2.200132; For Android: Smart Switch Mobile lets you transfer data between GALAXY phones.
-->The scheduler maintains a queue of executable threads for each priority level. These are known as ready threads. When a processor becomes available, the system performs a context switch. The steps in a context switch are:
- Save the context of the thread that just finished executing.
- Place the thread that just finished executing at the end of the queue for its priority.
- Find the highest priority queue that contains ready threads.
- Remove the thread at the head of the queue, load its context, and execute it.
The following classes of threads are not ready threads. Balsamiq mockups 3 5 17 inch.
- Threads created with the CREATE_SUSPENDED flag
- Threads halted during execution with the SuspendThread or SwitchToThread function
- Threads waiting for a synchronization object or input.
Until threads that are suspended or blocked become ready to run, the scheduler does not allocate any processor time to them, regardless of their priority.

The most common reasons for a context switch are:

- The time slice has elapsed.
- A thread with a higher priority has become ready to run.
- A running thread needs to wait.
When a running thread needs to wait, it relinquishes the remainder of its time slice.
