Application crashes or freezing on Windows PC

Because the failures now affect several programs, first identify whether they share a faulting module or background dependency rather than reinstalling each application again. Reproduce one crash, note the exact time, then open Event Viewer and inspect Windows Logs > Application for Application Error and Windows Error Reporting events, especially IDs 1000 and 1001. Record the faulting application, module, exception code, and path. Install current Windows, application, and device-driver updates. Then run DISM /Online /Cleanup-Image /RestoreHealth followed by sfc /scannow from an elevated terminal. Test the affected programs in a clean boot; if they work, re-enable non-Microsoft services and startup items in batches to isolate the conflict. If the same application still fails, repair or update it and provide its vendor with the event details. For persistent unexplained crashes, collect an application-specific Windows Error Reporting dump for analysis.
