Shared memory is a mechanism that allows multiple processes to access the same memory space. This can be useful for sharing data between processes, or for creating a shared pool of memory that can be used by all processes. In Windows, there are a few different ways to check shared memory.
One way is to use the Task Manager. To do this, open the Task Manager and click on the Performance tab. Then, click on the Memory tab and select the Shared view. This will show you a list of all the shared memory segments in the system, along with their size, owner, and other information.
Another way to check shared memory is to use the Performance Monitor. To do this, open the Performance Monitor and click on the Data Collector Sets node. Then, click on the User Defined node and select the Shared Memory data collector set. This will show you a list of all the shared memory segments in the system, along with their size, owner, and other information.

Tips on How to Check Shared Memory in Windows
This section provides valuable tips to effectively check and manage shared memory in Windows systems, ensuring optimal performance and efficient resource utilization.
Tip 1: Utilize the Task Manager
The Task Manager offers a straightforward method to monitor shared memory usage. Access the “Performance” tab and select the “Memory” tab, then switch to the “Shared” view. This will display a comprehensive list of shared memory segments, their sizes, and associated processes. This information can aid in identifying potential memory hogs or performance bottlenecks.
Tip 2: Leverage the Performance Monitor
The Performance Monitor provides advanced monitoring capabilities for shared memory. Navigate to the “Data Collector Sets” section, expand “User Defined,” and select the “Shared Memory” data collector set. This will present detailed metrics on shared memory usage, including segment sizes, owners, and utilization patterns. This data can be valuable for performance analysis and troubleshooting.
Tip 3: Employ Sysinternals Tools
Sysinternals tools offer a powerful suite of utilities for managing and troubleshooting shared memory.
