JSI Tip 0008 - Stop CHKDSK from running at boot time.

1.Edit: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSessionManager
2.Change the BootExecute entry from:

autocheck autochk * /.........

To:

autocheck autochk *

If you have scheduled CHKDSK for multiple volumes, there willbe an autocheck entry for each volume. Delete the string fromthe BootExecute registry value for each volume you do not wantchecked. If you have NT 4.0, SP2, a new command line utility,CHKNTFS, will assist in preventing repeated CHKDSKs duringreboots if the "dirty" bit is set. Type CHKNTFS /? andsee KB article Q160963.
