Windows version Version of Microsoft Windows.
Windows mode This field now shows the internal version number and build number
ProductId (Windows 10 only): The product ID code and (if known) name, e.g. 1709, Fall Creators 2017
Swap file Size of the virtual memory simulated on your hard disk. The maximum size allowed is shown.
Free memory Free memory, including memory simulated on disk (swap file). In newer Windows versions, this value is meaningless because it's always equal to the total amount of memory. Total Commander therefore shows the amount of unallocated memory, and a percentage value which shows the "memory load". If this value approaches 0 you should think about buying additional memory.
Free resources Free system resources in %. If this value gets too low, you cannot start additional programs. The shown value, normally called "free resources", is the minimum of free GDI (graphics) and USER (Window management) resources, shown in brackets. The value isn't available in Windows NT, but isn't a problem there either.
Time since win. start Elapsed time since Windows was last started. Unfortunately, on Windows XP and older, the counter wraps to 0 approx. every 50 days.
Temporary dir Defines the directory where programs put their temporary files. This is defined via environment variable temp.
