CPU Meters

Drive Information.

SMART information is available on newer hard disks. It provides useful information and status of the hard disk. I think the most useful information it provides is the hard disk's temperature. The temperature is important because a hard disk can fail or a least become unreliable if it's temperature exceeds a certain value.

Note: SMART information is not currently available on Windows 7.

About System Spec

System Spec is a self contained standalone EXE which can be run without installing. It lists a specification of your Windows PC without listing lots of useless memory address and unnecessary information.

This utility can be used for comparing the specifications of different machines. The spec can be outputted to a text file or printed to a report.

In this new version the spec can be saved to a CSV file so that it can be opened in programs such as Excel.

Export to HTML

As well as export to CSV System Spec can now export the system information displayed on the main system to a HTML file. This HTML file can then be uploaded to your website to show off your PC's Spec. To export to HTML go to File - Export to HTML. The HTML output looks like the main screen and report. Click here to see an example of the HTML output.

Windows function such as shutting down and run can be performed from the System menu. The Control Panel menu allows you to quickly open items from the Control Panel.

Run in Silent Mode

Silent mode allows it to be called from a batch file or login script to produce a spec to a text file without having to use the user interface.

Command line:-
SysSpec.exe /auto c:\details.txt

Note: Only the information from the main page is saved.

The specification can be printed as a report, copied to the clipboard and save to a text file or CSV file.

Windows Compatibility

This software has been tested and is fully functional on Windows 2000 and XP. It will also run on Windows 98/ME but some information may not be displayed. It's is recommended that you install WMICore on Windows 98/NT4 machines. System Spec will not run on Windows 95. System Spec will run on Windows 7 32 & 64 bit versions.

Windows 8 Compatibility.

System Spec is still work in progress of Windows 8.

Note to antivirus scanner users

McAfee virus scanner may report System Spec as a backdoor Trojan. Please ignore this warning as it is incorrect. A DAT file to suppress the heuristic detection, which will be included in a future DAT set, can be downloaded from their updates pages. F-Secure also unnecessarily blocks the EXE file from being downloaded from here but the ZIP file seems OK.
