Thanks @kevinjwalls for reviewing this PR The behavior has not changed; the old API GetTempPath also returns different temporary paths for SYSTEM and non-SYSTEM accounts, similar to the new API GetTempPath2. For SYSTEM accounts: GetTempPath: C:\WINDOWS\TEMP\ GetTempPath2: C:\WINDOWS\SystemTemp\ For non-SYSTEM accounts: GetTempPath: C:\Users\\<user>\AppData\Local\Temp\ GetTempPath2: C:\Users\\<user>\AppData\Local\Temp\ ------------- PR Comment: https://git.openjdk.org/jdk/pull/20600#issuecomment-2329598028
