Windows batch files: Strange behavior of the IF command

Posted on 2022-09-27 by guenni

Users who have upgraded to the version are complaining about bugs – and some features like tabs in Windows Explorer won't come until October via the "Moments 1" update. Gamers are complaining about bugs, and Microsoft has already had to admit to an upgrade block on certain versions of the Intel Smart Sound Technology driver.
