KUserInit.exe Error Displayed at Logon (4211825)

Many third-party applications can cause issues with KUserInit.exe:

1. Anti-Virus
2. Host-based Intrusion Prevention System (HIPS)
3. Dell Data Protection Enterprise (DDPE)

See notes for each in the Resolution section.

Anti-Virus

• Whitelist the executable: C:\Windows\System32\KUserInit.exe

Host-based Intrusion Prevention System (HIPS)

• Whitelist the executable: C:\Windows\System32\KUserInit.exe

Dell Data Protection Enterprise (DDPE)

• Ensure DDPE is NOT encrypting the KUserInit.exe file. This is a known issue that will cause KUserInit.exe to fail to launch, because DDPE is not active at user initialization and is unable to decrypt the file at logon.
