What
The env section of a settings file sets environment variables for Claude Code. Claude Code handles some of these variables specially. More Windows variables are now in that group, including:
SYSTEMROOTandWINDIRCOMSPECPROGRAMFILESandLOCALAPPDATAPATHEXTPSMODULEPATHHOMESHARE- the
ONEDRIVE*variables
The same group also decides which env keys from project or local settings are reported when a bundle is uploaded to the cloud.
Why
If your settings set any of these Windows variables, Claude Code now treats them differently from before.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
The finding does not say what the special handling does to these variables.
