If Store app not opening in Windows 10 and running App troubleshooter reports unresolved "Windows Store cache may be damaged" message, fix it manually here.

Whenever there happens any issue with Windows Store, users are often suggested to run Windows Store Apps troubleshooter. This built-in troubleshooter helps you to identify the problem with Store and fix it automatically. But sometimes, automatic fixing using this tool may not work, yet you got to know what the issue is so that you can solve it manually.

This post talks about one such issue which is not fixable by Windows Store Apps troubleshooter and it is labelled as “Windows Store cache may be damaged“. We recently came around this problem on a Windows 10 Pro running system for which Store app wasn’t opening and it got stuck at splash screen. Running the troubleshooter found this problem and it seems that we need to fix it manually, as it is quite clear from below screenshot.
