I actually used this for the first time last weekend (for a concert ticket). Worked well enough to display the QR code, although the labels were all sorts of messed up (although that might just have been the file itself).

the time limit should be way longer given how long previous versions of Windows have been supported.

What version would that be?

• Windows XP: 2001-10-25 to 2014-04-08, ~12.5 years
• Windows Vista: 2007-01-30 to 2017-04-11, ~10 years
• Windows 7: 2009-10-22 to 2020-01-14, ~10 years
• Windows 8/8.1: 2012-10-26 to 2023-01-10, ~10 years
• Windows 10: 2015-07-29 to 2025-10-14, ~10 years

The first one reminds me of this classic

Aren’t forums absolutely notorious for forbidding “thread necromancy”?

They’re trying to accomplish a joke.
