Windows XP - Slow Boot Up Problem. [SOLUTION]
Posted by Rob Astbury on 22 March 2012 08:49 AM

This Information is to fix a common problem that is occuring with many of the PC's recently, in that after the Windows XP logo is shown, the computer will stay on a Black Screen for a while; ~3-20 mins but times do vary. This should normally be about 6 seconds. There is a permanent solution to this that will be included in a Windows Update around May 2012, but for now. this solution below will resolve the issue.

How to use the Recover console CD to fix the Windows XP Slow Boot Problem

- Download Recovery Console CD from this ticket and Unzip. Burn the .iso file using CD burning software (, is a freeware cd burner software. if you don't already have one)
- Insert Recovery Console CD and Restart PC
- When Dell Boot Logo Appears PRESS F12
- Select CD-Drive, press enter
- Once recovery console loads (may take 1-2 mins), Press "R" to launch into recovery console (Blue Windows screen, second option)
- Select which drive has the windows installation, Probably just "1" for one hard-drive installed. press enter key ( Black Windows command prompt)
- password should be blank, just press enter key
- when you see "c:\windows\" type the following "cd system32\config" and press enter (Cursor does not flash at this point)
- (optional) you can type "DIR" to see a list of the files within this directory if you like.
- Type "Rename default defaultBACKUP" and press enter, this will change the "default" file to a "defaultBACKUP"
- Type "exit" and press enter, this will restart the PC.
- You may now remove the recovery console CD, and the Slow Bootup time should be resolved.
- Once back in windows, Run the Registry Edit file that has been attached to this ticket to stop the issue from re-occuring in the future.

UPDATE:- Instead of running the registry fix, alternatively; you may uninstall "Intel(R) Management Engine Component" and that should stop the issue from re-occuring

Hi Rob,

Just tried the quick fix of removing the Intel(R) MEC to no avail. I'll try the full reload when I get a CD.

Sorry for any confusion. If your Slow boot problem exists; then you will still need to run the CD to remove the problem. Uninstalling the Intel MEC will only stop the problem from reoccuring again in the future.

For anyone having Problems with the Recovery CD (not working / blue screening) here is an ALTERNATE solution...

To remove the "Default" file, using Ubuntu (freeware Linux Based Operating System)

This OS will run from CD without the need to install it on the target computer.

Download it from here and burn onto a CD;

once burnt, reboot and press F12 on boot logo to gain access to boot menu, select the CD Drive.

This should now boot into Ubuntu, Select "Try First" (Run from CD) NOT the "Install Software" (install to hard-drive).

you should now be able to use the OS, select the THIRD icon from the TOP LEFT corner. and select your hard-drive.
now navigate to "Windows/System32/config" and you should see a file named "DEFAULT" please either rename this to something else (DefaultBackup) OR delete the file.

Shutdown Ubuntu via the TOP RIGHT icon.

Any Problems? please raise a Support Ticket or Comment on this Knowledge Base Article.

Thank you very much!!!!! This solution solved my problem!!
i'v registered here to tell you: Rob Astbury, you are awesome! Thank you again!

Can you tell me how did you find this solution?
I've monitored boot process on pc with bootvis/xbootmg, but no success:
ntkrnlpa.exe thread consumes 100% cpu on "black screen period", no disk activity, the root cause of problem not founded.

You wrote in the beginning of this article:There is a permanent solution to this that will be included in a Windows Update around May 2012, but for now. this solution below will resolve the issue.
Do you know, a permanent solution available in windows update now?
p.s. sorry for my English ;)

If you are having problems with the supplied recovery disc (blue screening during install loading screen), it may be due to your hard-drive being set to AHCI mode. go into the bios and change this to ATA mode and you should be able to use the recovery disc.

Ilnaz - This solution was discovered with the help of Dell technicians, as it seemed to be commonly occuring on many of our PC's under test, i have not heard any more on when intel / windows will be issuing a fix to prevent this in the future but this fix does seem to stop the issue from re-occuring. Thanks for your comments, glad i could be of help.

Hi Rob,

Thank you very much on the solution. I would like to confirm that the sollution works not only on Dell machines but also on all machines with Intel chipset that have AMT enabled and Intel Management software installed.

One suggestion though, as i figured it out, you don't have to do the renaming stuff as long as you can login to computer (even after 20 min). You only need to delete the “HKEY_USERS\.Default\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Digest” folder, and stop the service (with your reg fix).
Anyways, just wanted to say thanks.

Hi I only signed up for this forum because of this fix I normally never apply for forums but I wanted to let you know how much this fixed my problems with computers. I have been struggling to find a possibly solution for this for over 2 years and the only solution I found was to reformat or possibly re adjust the boot.ini but this solution solved everything. As a company I appreciate this so much. Thank you Rob

I also just registered to thank you, Rob. Couldn't find a fix to this anywhere. Dell PC running Intel MEC here.
