   This issue is resolved in Npcap 0.996, released today. https://npcap.org/#download

   Because Npcap 0.995 consistently crashes some systems, the Npcap 0.996 installer will offer to disable the npcap driver service on the next boot so that the installation can be reattempted. You can also manually disable it by following these steps:

   1. In an Administrator command shell, run: sc.exe config npcap start=disabled
   2. If Npcap was installed in WinPcap API-compatible mode, also run: sc.exe config npf start=disabled
   3. Reboot. There may be one more BSoD crash at this point, but it will be the last one.
   4. Run the Npcap installer to upgrade Npcap, or uninstall it via "Add or Remove Programs" control panel. Since the service is disabled, it can safely be removed.
