Windows 10 Slow Boot Time, require help to check Windows Performance Analyzer Logs

Writer Emily Wong

I recently migrated (cloned) Windows 10 from a SSD to a M.2 PCIe SSD. Everything works and runs fine, but I realized Windows requires ~85 to 115 Seconds to boot. I'm not sure if it takes so long only since migration or if it already did before as I used to mostly use Wake-on-Lan to start the PC minutes before I went to the PC and therefor didn't care. However, I spent most of the day trying to find my way through Windows Performance Analyzer-Logs for the reason of the long boot time, but by now I kind of feel lost in it. On my research I found similar threads on superuser.com and I hope someone more expierenced could take a look into my issue as well and/or is willing to explain me how to track down the issue myself. Link to WPA-Logs in .etl file format:

I saw your boot trace and it seems that the boot delay you experience is caused by the hibernation file (hiberfil.sys)

In the CPU precise graph you can see that the SMSS process spent 45s waiting on the PoPEnableHiberFile function.

CPU Precise Graph

This is correlated by the File I/O graph where you can see SMSS process spending 43s accessing C:\hiberfil.sys

File I/O Graph

You need to disable the hibernation in order to delete the c:\hiberfil.sys => powercfg -h off

then restart your computer and see if that help.

if you need to turn the hibernation back issue this command => powercfg -h on
