VeraCrypt 1.25.7 (for Windows 7, 8.x, 10)

[German]In December 2021, the developers of the encryption software VeraCrypt had released version 1.25.4, which was indeed upgraded for MacOSX on Apple's Silicon M1 processors. But for Windows only systems from Windows 10 were supported. This has been corrected with version 1.25.7, released on January 7, 2022, which again supports Windows Vista, Windows 7 and Windows 8/8.1.

VeraCrypt is data encryption software, specifically for full or partial encryption of hard drives and removable media. VeraCrypt first appeared in 2013 as a fork of TrueCrypt and is partially compatible with it. The following description can now be found in the release notes of VeryCrypt:
