Windows 10 boot time : previously 20 seconds, now 6-8 X more

Question

Previously it took about 20-30 seconds to boot my Windows 10 Computer. I just don't understand why it does now take up to eight-times longer to start up, even though I have disabled most the useless services on Windows. I cannot find out how to fix this issue.

EDIT 1: I think it is maybe because of this (it is thrown four separate times):

BOOTLOG_NOT_LOADED \SystemRoot\System32\drivers\dxgkrnl.sys

EDIT 2: WPT report

Install the WPT (part of the Win10 SDK: https://dev.windows.com/en-us/downloads/windows-10-sdk), run WPRUI.exe, select **First Level**, **CPU Usage**, **DiskIO**, **FileIO** and under **Performance Scenario** select **Boot**. **Number of iteration** can be set to **1** and click to start. This reboots Windows and captures all activity during boot. After the reboot let the countdown tick to 0. Zip the large ETL file into zip/RAR file, upload the zip (OneDrive, dropbox, google drive) and post the share link here. I'll analyze your boot — magicandre1981, Apr 23 '17 at 16:19
Thanks for your help : here is the result : https://www.dropbox.com/s/epoxxbjjlvl4apw/DESKTOP-OTIF3AP.04-23-2017.21-21-57.Boot_1.etl.zip?dl=0 . (compressed : 101 Mo , uncompressed : 884 Mo ) — jy95, Apr 23 '17 at 19:46
Question one - what services have you disabled? Question two - How many applications do you have set to "Enabled" in the startup tab of your task manager? Question three - What are your system specifications? Question four - What version of Windows 10 are you using, and what build number? The .sys file you mentioned is a DirectX component. Have you tried to reinstall DirectX? — Charles, Apr 24 '17 at 15:29

After I loaded the ETL into WPA.exe, I clicked on Profile-> Apply, "browse catalog" and select the file FullBoot.Boot.wpaprofile I saw this overview

Here the WinLogonInit subphase is slow (79 seconds):

What Happens in This Subphase
The WinLogonInit subphase begins when SMSSInit completes and starts Winlogon.exe. During WinLogonInit, the user logon screen appears, the service control manager starts services, and Group Policy scripts run. WinLogonInit ends when the Explorer process starts.

Visual Cues WinLogonInit begins shortly before the logon screen appears. It ends just before the desktop appears for the first time.

WinLogonInit Performance Vulnerabilities Many operations occur in parallel during WinLogonInit. On many systems, this subphase is CPU bound and has large I/O demands. Good citizenship from the services that start in this phase is critical for optimized boot times. Services can declare dependencies or use load order groups to ensure that they start in a specific order. Windows processes load order groups in serial order. Service initialization delays in an early load order group block subsequent load order groups and can possibly block the boot process .

And here the CreateSessionis slow:

and here the TrustedInstaller is working (component to install updates). Do you see error messages during shutdown/boot that changes must be reverted? I see that your kernel is 15063.138, but the BuildLab string is still 15063.0.amd64fre.rs2_release.170317-1834. So maybe your Windows is in an inconsistent state. Remove the update KB4015583 via controlpanel->programs & features ->installed updates, reboot and reinstall the update.

Next the ExplorerInit phase is also slow and takes 48 seconds to finish:

What Happens in This Subphase

The ExplorerInit subphase begins when Explorer.exe starts. During ExplorerInit, the system creates the desktop window manager (DWM) process, which initializes the desktop and displays it for the first time. This phase is CPU intensive. The initialization of DWM and desktop occurs in the foreground, while in the background the service control manager (SCM) starts services and the memory manager prefetches code and data. On most systems ExplorerInit is CPU bound, and timing issues are likely the result of a simple resource bottleneck.

Visual Cues
ExplorerInit begins just before the desktop appears for the first time. There is no clear visual cue to indicate the end of ExplorerInit.

Here the steps PreStartTasks,LaunchExperienceHost (Startmenu, action center all the new UI) and PerUserSetup are slow:

When I look at the disk graph, I see that the disk is busy during all boot phases:

So, your slow 1TB Seagate Samsung Spinpoint M8 (ST1000LM024 HN-M101MBB) also slows down boot a lot.

The best is to remove the DVD drive, buy a HDD caddy add the HDD here and use a SSD for the OS + programs.

But attention, make sure you buy a caddy that has a jumper

to prevent ACPI.sys issues.

Great thanks for your analysis with full details. If you can resume the todo list please (already choose your answer as best possible one)? — jy95, Apr 24 '17 at 21:14
replace HDD with SSD gives you most perf boost. first insert the SSD into the hdd caddy, boot from HDD, use a clone tool to clone Windows to SSD, shutdown, swap drives, so that HDD is on caddy and now boot from SSD. — magicandre1981, Apr 25 '17 at 04:21

Windows 10 boot time : previously 20 seconds, now 6-8 X more
