Thanks peste, but unfortunately that still eventually comes up with the unknown company's logo during the Windows 11 fresh install ( on an empty SSD). However I think it progressed further through the Windows install than it did previously, as if the missing AUTOPILOT_MARKERs are not sufficient to get rid of Autopilot, and it falls back to using some additional method while it contacts Microsoft 365.

Does it perhaps read some other data from the hardware config, and then use that to create the hardware hash used to identify the laptop on the Microsoft end ? I thought changing the...

Dell Latitude 7490 Autopilot issue : is anyone able to help remove Autopilot from the attached 7490 bios , please ?
I'm able to install Windows on the laptop using the OOBE\bypassnro workaround, but I'd like to get the laptop into a state for the next user where it doesn't come up with this unknown company's logo whenever they reset the PC or re-install Windows ..
Motherboard : DAZ40 , LA-F322P Rev.2.0(A01)
Service Tag : 7XD4HR2
thanks!...

P.S. I should add that the reason I want to change the Service tag is that the laptop is enrolled to Microsoft Autopilot, and this is what I want to get rid of : I had assumed that changing the service tag was the best way to do this, but I have just discovered a separate active thread Dell Microsoft autopilot issue on this forum with screenshots outlining how to get rid of Autopilot by editing/invalidating the AUTOPILOT_MARKER sections using a hex Editor. I tried doing this on my bios, but wasn't clear on how exactly to do the invalidation step , so was not yet successful ..

hi, I'm trying to change the Service Tag on my Dell Latitude 7490 and would appreciate some pointers/links on the best way to do this.

I'm thinking to get the BIOS into Manufacturing mode , from where I can simply type in a new Service Tag. But I've not been able to find how to get it into Manufacturing mode.

I have recently got a T48 programmer which seems to work fine with the Latitude 7490/7400 in-circuit, and I successfully used it with rex98's excellent -8FC8 patcher to remove the system password on a colleague's Latitude 7400 : it appears to work by putting the...

Many thanks for this great little tool : thanks to this , I bought my first ever T48 EEPROM programmer, and managed to re-program my Dell Latitude 7400 ( in-circuit , as a bonus! ) and get it into Manufacturing mode to remove the system password. Very pleased with myself .. thanks again
