How to Clean Windows Bluetooth Pairing Logs & Diagnostic Traces
Location & Quick Verdict
C:\Windows\System32\Winevt\Logs
Windows logs Bluetooth LE connection attempts, RFCOMM socket events, and audio packet drops into dedicated event log files.
Why Kernel Minidumps, WER Archives & ETW Traces Fill Windows Bluetooth Pairing Logs & Diagnostic Traces
Whenever a hardware driver times out (TDR), a background service faults, or Windows Servicing installs a patch, the Windows Error Reporting (WER) pipeline and kernel crash handler write uncompressed memory snapshots (.dmp) and verbose text logs into C:\Windows\System32\Winevt\Logs. A single full or kernel memory dump or LiveKernelReports WATCHDOG snapshot can consume 500 MB to 4 GB of disk space immediately.
Unless you are actively debugging a recurring Blue Screen of Death (BSOD) with WinDbg right now, historical crash dumps and rotated CBS/DISM log archives inside C:\Windows\System32\Winevt\Logs serve zero runtime purpose. Deleting Windows Bluetooth Pairing Logs & Diagnostic Traces safely reclaims 0.5 GB – 3.0 GB without affecting Windows stability or future error reporting.
