Sometimes latest versions of the software can cause issues when installed on older devices or devices running an older version of the operating system.

Software makers usually fix these issues but it can take them some time. What you can do in the meantime is to download and install an older version of PuTTY 0.83 (64-bit).

What's new in this version:

- Support for ML-KEM, the NIST-standardised post-quantum key exchange mechanism. (In addition to NTRU Prime, which has been supported since 0.78.)
- Support for full Unicode file names in Windows file selector dialogs. (However, these do not yet round-trip through a saved session.)

Fixed:
- psftp -b works again
- assertion failure if an SSH connection times out at the login prompt
- crash in Pageant if an SSH connection is abandoned while waiting for a deferred decryption passphrase
- tight loop if PuTTY tried to send an empty answerback string
- accidental truncation of some configuration edit boxes' contents to 127 characters
- Windows XP support was accidentally broken, and now reinstated
- restored interoperation with third-party tools that auto-fill login prompts by sending ^M for Return
- confusion when terminal window resized by tools like FancyZones
- the small keypad keys didn't reliably work in the terminal on Unix
