autocheck

About this tag
The autocheck tag on WindowsForum.com covers issues related to the Windows autochk utility, which runs during boot to check disk integrity. Common problems include autocheck not being found, skipping autocheck, or the registry key at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager persistently adding autocheck commands like autocheck autochk /r \??\C:. Users report that autocheck errors often accompany other boot failures, such as the c000021a fatal system error, and can cause slow boot times. Discussions focus on troubleshooting autocheck registry entries, understanding that autocheck messages are symptoms of underlying disk or system issues, and finding solutions to prevent unwanted autocheck behavior on Windows 7 and Vista systems.
