Windows profile takes 20 minutes to sign in

Scenario

A user can authenticate quickly but waits an excessive amount of time for the desktop to fully load.

Recommended Resolution Path

1. Measure logon breakdown: GPO, scripts, OneDrive, profile size, and redirected folders.
2. Review startup apps and shell extensions that delay explorer initialization.
3. Check file server latency if profile or redirection data lives on the network.
4. Create a test profile to compare baseline performance.

Technician Notes

Confirm the business impact, document the root cause, and capture any preventative follow-up in the PSA or client knowledge base.
