I agree with your comments.

Dell escalations team advised:

"There have been some delays to the updates for this issue - these can be sometimes be down to issues found during validation testing that require further investigation.

I would expect the website to be updated as further information becomes available."

With regard to the market for disabling the Intel Management Engine, this is only applicable to new systems.  I don't have any further information on this as this is a business move from Dell.  You could contact Dell Sales though to check further what models are included for this.

I did contact them and rest assured it was an exercise in fultility.

Regarding article SLN308237, the web page has many duplications, inconsistencies and out-of-date information and they do not bother to correct the web page.

Not very professional.  All my HP business notebooks were updated very quickly with updates from the HP support seection.

The update dates  for my laptops have moved thru the following dates:

12-01-2017

12-08-2017

12-22-2017

and today presenting 12-25-2017 (Christmas Day)- the next update I suspect will be 01-12-2018.

When it comes to the replacement of my company's laptops, I can assure Dell will not be considered.

I can fully comprehend why people are complaining about Dell's services.

The date has now changed to 12-23-2017 (fifth change).

Now the date has been changed for a sixth time. Dell are clueless.
