I can see the previous suggested steps from the Q&A Assist already covered how to uninstall the app through Settings, Start menu and Control Panel.
If PC App Store TM is still stuck on your screen or won’t uninstall, it may still be running in the background. In that case, please press Ctrl + Shift + Esc to open Task Manager, look for anything named “PC App Store,” and select End task. Once it’s fully closed, try uninstalling it again from Settings (Windows logo + I keys) > Apps > Installed apps. If the uninstall still doesn’t go through, restart your PC and try again right after signing in, as a reboot can clear anything that was blocking the process.
If the issue continues, you can try removing it in Safe Mode with Networking, which prevents most background processes from interfering. To do this, go to Settings > System > Recovery, then under Advanced startup select Restart now. After your PC restarts, choose Troubleshoot > Advanced options > Startup Settings > Restart, then press 5 or F5 (Enable Safe Mode with Networking). Once your PC loads into Safe Mode, open Settings > Apps or Control Panel and uninstall the app from there.
After you’re able to remove it, I recommend running a full scan using Windows Security to ensure there are no leftover files or related components. Just as a quick note, Google Play is not used on Windows PCs, it is designed for some supported Android and Chromebook devices, so on your HP computer it’s best to install apps only from the Microsoft Store or official websites to help avoid similar issues in the future.
If the app still appears after these steps, please let me know what you’re seeing and I’ll be happy to guide you further.
