Startup: Task Manager → Startup apps. Disable leftover Kingsoft updaters. If a splash screen still appears at login, you missed a second installer. Windows notes · will not open.
macOS
Quit the apps. Drag WPS from Applications to Trash. Check Login Items. Remove leftover containers only if you know what you are deleting — that is also your local recovery cache. Mac.
Linux
Deb: sudo apt remove the wps packages you actually installed, then sudo apt autoremove. RPM: use dnf/yum. Snap: snap remove. Old community packages and a new official Deb on the same box is how launch errors stay after “uninstall.” Linux.
Android and iOS
Long-press → uninstall, or delete from the App Store list. Sign out of WPS Cloud first if you are handing the phone to someone else. Local files in the app sandbox go with it; Drive copies do not.
You still want the files
