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

All commands support speech on demand mode.

• NVDA+Shift+E: presents used ram, average processor load, and battery info if available (battery info announcement is deprecated).
• 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+3: presents the used and total space of the static and removable drives.
• NVDA+Shift+4: presents battery percentage, charging status, remaining time (if not charging), and a warning if the battery is low or critical (deprecated).
• NVDA+Shift+6: presents CPU Architecture and Windows version and service pack numbers.
• NVDA+Shift+7: presents the system's uptime.
• NVDA+Shift+8: presents information on the wireless connection, ssid name and strength, or no ssid if there is none available.
• Unassigned: presents information about the graphics processing unit (GPU).

You can change these shortcut keys via input gestures dialog.

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

• 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 which uses 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, there might be delays when obtaining disk usage information.
• When announcing processor architecture information, "x86" and "AMD64" refer to 32-bit and 64-bit (x64) Intel and AMD processors, respectively.
• Installing the add-on on Windows 10/11 LTSC is not supported.
