    Issue description

    In rare cases after the Acronis True Image installation, you may notice that your Windows system started taking more time to boot. This article helps you to find out what slows Windows boot, provides steps to solve the issue and describes the information to collect for further investigation if need be.


    To troubleshoot the issue you need to understand which service or process causes slower boot.

    Where to look for

    To check what causes the issue, you need to open Windows Event Viewer on your PC.

    To start Event Viewer using Windows interface: 

    1. Click Start.
    2. Click Control Panel.
    3. Click System and Maintenance.
    4. Click Administrative Tools.
    5. Double-click Event Viewer.

    To start Event Viewer using a command line:

    1. Open Command prompt. To open the Command prompt, click Start, click All Programs, click Accessories, and then click Command Prompt.
    2. Type eventvwr 
    3. Press Enter.

    When the event viewer is open, create a custom view for Windows boot logs:

    1. In the Action menu, choose Create Custom View:
    2. In Logged, leave Anytime selected. In Event level, select all check boxes. In By log, navigate to Applications and Services Logs  -> Microsoft -> Windows -> Diagnostics-Performance and select the Operational check box.
    3. In Includes/Excludes Event IDs, type 100 and click OK to save your custom view. You can save it with any name (for example 'Boot time').
    4. Create another custom view. Repeat steps 1 and 2. In step 3, type 101-110 in the Includes/Excludes Event IDs box. Save this view and name it 'Boot Degradation'.

    Finding out the cause of slower boot

    The 'Boot time' contains information about your operating system boot time:

    Find the date when you have installed Acronis True Image and compare the entries with several previous boot durations. You can also open Details and compare 3 parameters: MainPathBootTime, BootPostBootTime, BootTime.

    This parameter shows the time between the animated Windows logo appears and the desktop appears. The system is usable at this point, but Windows is still working on low-priority tasks in background.

    This parameter shows the time between the desktop appears and the point at which you can actually begin using the system.

    This is the value you have seen on the General panel under Boot Duration

    If you have found a significant degradation in Windows boot time since Acronis True Image installation, you need to review the second Custom view that you have created - 'Boot Degradation'.

    In this view, check the General tab to find out if any Acronis processes have made your Windows boot slower. The values you need to review here are Total time and Degradation time:

    If Acronis Active Protection service causes slower boot

    Acronis Active Protection service depends on Windows Cryptographic Services. When new processes are created in the system Acronis Active Protection verifies its digital signature with WinVerifyTrust() API that relies on CryptSvc providers. When CryptSvc service is not yet available at the time of signature verify process, WinVerifyTrust() does a blocking wait until the cryptographic service is up and running.

    This prevents Active Protection service from handling another events correctly until the process of verifying digital signature completes.


    1. Temporary disable Acronis Active Protection in True Image settings.

    2. Using Windows Registry editor, add "CryptSvc" service to "Active Protection" service's dependencies:

      1. Open Windows Registry editor: click Start, in Search type regedit.exe and press Enter.
      2. Navigate to HKEY_LOCAL_MAchine -> SYSTEM -> CurrentControlSet -> Services -> AcronisActiveProtectionService.
      3. Right-click DependOnService.
      4. In Value data, type CryptSvc
      5. Click OK, save changes.

    3. Enable Active Protection feature and restart your PC.

    Now you can check if the Windows statup time has accelerated.

    If you have found out that another Acronis process makes your Windows boot slower, go to the Collecting information step.

    Collecting information:

    1. Screenshots of the boot degradation Custom views that could show the degradation caused by Acronis processes.
    2. Activate debug logs for Acronis True Image: Collecting Debug Logs.
    3. System report from your machine using the AcronisInfo utility.

    With all the information collected, please, contact Acronis Support.
