DCH drivers only work with 6th Gen and Newer INTEL. OEM drivers are the ONLY option now that 1st thru 5th gen are End of life.    Intel HD 4600 Graphics driver Version 20.19.15.5058, A05 The update addresses Intel Security Advisory INTEL-SA-00166. . [URL]    
Following the Install of Win10 Spring Release version 1803, I have been experiencing issues with my Display.  Posting in "MicroSoft Answers" the reply was that many users experienced many issues after 1803 Installed to include Display issues and the recommendation was to Update my Graphic Driver (Intel HD Graphics 4600).  I went to the dell Site and the Driver offered was the same one installed in my Desktop.  I then went to the Intel site, installed the Scan for updated Drivers software and it found there was an Updated Graphic driver available.  I tried to Install the Updated driver and got the message in so many words, I must get my Drivers from Dell.  We all know that Dell has designed their hardware for the most part with exclusivity as to Drivers...thus the user can only Install driver Updates available at Dell's Site.  I sent an email to dell outing my Issue and that the Driver available at Dell is an older out of date Driver.  I realize my Desktop is Out of Warranty, but was not pleased when the response was, too bad your Desktop is no longer in Warranty and we won't assist you. My issue is if Dell is going to sell PC's where Dell is the exclusive provider of Updated Drivers, and, Dell does not keep the Driver Download dell site current with current Drivers than how does a dell owner Update their drivers?  If Dell has designed their PC's to be exclusive as to Drivers, than Dell has taken on the responsibility to Keep the available Drivers current at the Dell Drivers download site.  This is not a Warranty issue, it is an issue of responsibility...lock your customers out of Downloading Drivers from the Manufacturer, then you better keep your drivers at your site current.  Or, is it now Dell's way to say to customers, we will force you so to speak to buy newer PC's if you are having an issue where you need the current Driver....by not having that newer driver available your only choice is to Buy a New PC. Dell should NOT lock users out via their Driver designs to be unable to download and install Drivers from the Manufacturer  its like they have you their Hostage, you need a Newer driver, its not at our Website, buy a new PC.  The Graphic driver at the dell Website is very outdated. I can not Roll back the 1803 Update, it been longer than 10 days.  I do not want to preform New Win10 Install.....I just want to Install the newest Graphic Driver for my Intel Graphic Driver and since it is not available at Dell, get it from Intel.   How do I get dell to assist me and many others facing the same issue? Is there away to Unlock this proprietary\exclusive Driver Update Dell Only process so I can Install the Updated driver from in this case, Intel.
