Extremely long (20+ minutes) boot time in Windows 7 RRS feed

  • Question

  • I have a WPA capture from a Windows 7 boot that makes absolutely no sense.

    The PC in question is sitting at a blank screen after the Windows splash screen but before showing the desktop for over 20 minutes. Eventually it will boot and behave totally normal.

    The capture shows 1024 seconds (~21 minutes) for the Winlogin init phase.

    But when I look at the windows logon timeline, there's nothing there!

    What else can I look into to figure out what's causing this problem?

  • If there are errors or corruption of data on the system drive it can cause a long boot time because Windows is having a problem reading during boot up.

  • Open administrative command prompt and type or copy and paste:

    1) sfc /scannow


    2) chkdsk /scan

    3) When these have completed > right click on the top bar or title bar of the administrative command prompt box > left click on edit then select all > right click on the top bar again > left click on edit then copy > paste into the thread

    4) msconfig (in the pop up system configuration > move the dot from normal startup to selective startup > uncheck load startup items > click service tab > in left lower corner check hide all Microsoft services > in the lower right side click disable all > click apply or ok > do not reboot)

    5) taskmgr (in the pop up task manager > click on the start up tab > click on status so that the column sorts with enable rising to the top > right click on each row with enable and change to disable)

    6) shutdown /r (you will reboot the computer so that it is in clean boot)

    7) Evaluate the performance on your computer in clean boot during typical use.

    8) Are the boots faster or slower?

    9) Are the shutdowns faster or slower?

    10) How has the audio and video performance changed? Is it better, worse, or the same?

    11) Open task manager and view cpu, dis and moemory %.  Are the numbers better worse, or the same?

    Continue using clean boot indefinitely to monitor performance.
