Where Does Honkai: Star Rail Store Settings on PC?
Star Rail PC settings in the registry by region, and the cache wipe that fixes launch issues.
Last updated
Star Rail keeps PC settings in the registry: HKCU\Software\Cognosphere\Star Rail for overseas builds, a miHoYo key with the Chinese title for CN builds. Graphics flags and account cache live there, alongside LocalLow logs and the %LOCALAPPDATA%\HoYoverse cache.
None of it is progress: Trailblazers, pulls and story live on your HoYoverse account and server. HoYoverse support's own launch fix is deleting the registry key plus the HoYoverse cache folder, which resets local options without touching the account. Region and launcher (HoYoPlay versus Epic) shift exact names, so expect variation.
Where Honkai: Star Rail stores this, by platform
HKEY_CURRENT_USER\Software\Cognosphere\Star Rail
Overseas registry key (CN builds use a miHoYo key with the Chinese title). Logs in %USERPROFILE%\AppData\LocalLow\Cognosphere\Star Rail; cache in %LOCALAPPDATA%\HoYoverse. Progress is server side. No native Linux or Mac build exists.
Frequently asked questions
Star Rail won't launch. What should I delete?
Close everything, delete the Cognosphere Star Rail registry key and the %LOCALAPPDATA%\HoYoverse cache, then relaunch. That resets local settings only; account progress is server side and safe.
Will copying Star Rail files move my account to another PC?
No need and no effect. Log in with the same HoYoverse account and server on the new machine; local files hold settings and cache that rebuild themselves.
