Slow boot due to NTFS.SYS repeatedly calling NtfsWatchForDeveloperModePresence

Copper Contributor

I have a problem where NTFS.SYS will repeatedly call NtfsWatchForDeveloperModePresence, with a delay of 1s between calls, adding up to about 27s of boot delay.

The function appears to be requesting a registry key: HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\AppModelUnlock

This is a RegOpenKey operation, returning NAME NOT FOUND

This appears to be related to Windows checking if developer mode is enabled. Windows appears to somehow access this key at some point, since the settings for developer mode change if the registry keys are modified, but I was unable to see it get successfully accessed during the logs.


This registry key does exist, so it is strange that Windows cannot find it during boot.

Inplace upgrade repair, DISM, CHKDSK, all haven't fixed the issue. It is perhaps an issue with the Windows Developer Mode module itself.


How might I go about fixing this particular issue with Windows Developer Mode?
