Determines how programs interpret two-digit years.
This setting specifies the largest two-digit year interpreted as being preceded by 20. All numbers less than or equal to the specified value are interpreted as being preceded by 20. All numbers greater than the specified value are interpreted as being preceded by 19.
For example, the default value, 2029, specifies that all two-digit years less than or equal to 29 (00 to 29) are interpreted as being preceded by 20, that is 2000 to 2029. Conversely, all two-digit years greater than 29 (30 to 99) are interpreted as being preceded by 19, that is, 1930 to 1999.
This setting only affects the programs that use this Windows feature to interpret two-digit years. If a program does not interpret two-digit years correctly, consult the documentation or manufacturer of the program.
Specify the maximum year for which two-digit years are interpreted as being 21st century:
