Resource Monitor

• Authors: Alex Hall, Joseph Lee, Kefas Lungu, Beqa Gozalishvili, Tuukka Ojala, Ethin Probst, Kevin Derome and other NVDA contributors

This add-on gives information about CPU load, memory usage and other resource usage information.

Shortcuts

All commands support speech on demand mode.

• NVDA+Shift+E: presents used RAM (physical memory) and average processor load.
• NVDA+Shift+1: presents the average processor load and if multicore CPU's are present the load of each core.
• NVDA+Shift+2/5: presents the used and total space for both physical and virtual RAM (NVDA+Shift+5 is an alternative to NVDA+Shift+2 when the latter keyboard combination cannot be performed).
• NVDA+Shift+3: presents the used and total space of the fixed (built-in), removable, and network drives.
• NVDA+Shift+4: presents information on the wireless connection, network (SSID) name and strength, or no SSID if there is none available.
• NVDA+Shift+6: presents Windows version, CPU architecture (x86 (32-bit), AMD64 (x64(, ARM64), and exact build number (build.revision).
• NVDA+Shift+7: presents the system's uptime.
• Unassigned: presents information about the graphics processing unit (GPU; unavailable in secure mode).
• Unassigned: presents graphics processing unit (GPU memory usage information; unavailable in secure mode).

You can change these shortcut keys via input gestures dialog.

Usage notes

This add-on does not replace task manager and other system information programs for Windows. Also note the following:

• Apart from overall resource usage command (NVDA+Shift+E), pressing other commands twice will copy resource usage information to the clipboard.
• Resource information cannot be copied to the clipboard if running the add-on in secure screens.
• CPU usage is given for logical processors, not physical cores. This is noticeable for processors with Hyper-Threading where number of CPU's is twice the number of CPU cores. On some newer computers, not all CPU cores will have hyper-threading enabled.
• If there is heavy disk activity such as copying large files or while locating network drives, there might be delays when obtaining disk usage information.
• GPU information is given for Nvidia GPU's.
• When announcing processor architecture information as part of Windows version reporting, "x86" and "AMD64" refer to 32-bit and 64-bit (x64) Intel and AMD processors, respectively. This information does not refer to the name of the actual processor in use.
• Installing the add-on on Windows 10/11 LTSC is not supported.
