To remove PS_HOME or PeopleTools Home on a Microsoft Windows machine, go to the DPK_INSTALL\setup folder and run the command:

psft-dpk-setup.bat --cleanup

When using this command with PeopleTools Patch DPKs, it will only remove the PS_HOME present in your BASE_FOLDER. For example, C:\psft\pt\ptools8.57.02 folder will get deleted.
