INFO: Changing interpretation of a “two-digit year” in Windows 10/11

Today in Windows 10/11 the default behavior is, if you type in 12/31/29, this resolves to 12/31/2029.

If you type 12/31/30, this resolves to 12/31/1930.

Changing this behavior on a Windows 10/11 workstation:
If you are looking to change this behavior on an individual Windows 10/11 workstation, this is documented

in the article below:

Windows 10

1. In the search box on the taskbar, type control panel, and then select Control Panel.

2. Under Clock, Language and Region, click Change date, time, or number formats

3. Click Regional and Language Options.

4. In the Region dialog box, click Additional settings.

5. Click the Date tab.

6. In the When a two-digit year is entered, interpret it as a year between box, change the upper limit for the century.

As you change the upper-limit year, the lower-limit year automatically changes.

7. Click OK.

Creating a Group Policy Object to distribute this change organization wide
Applying this across an organization’s workstations would require the creation of a Group Policy Object (or modifying an existing one) that makes this change on every organization-managed workstation.
