The CPU is integrated on the MB and cannot be replaced. You can however install Windows 11 on your 3477. It may not meet the minimum supported hardware requirements but MS has posted information here which details how to bypass the CPU and TPM requirements. And Windows Central has more information here.
JO is correct. System board of this AIO is like laptop with cpu chip built in and not removable. Furthermore it is designed for intel 7th gen cpu with Intel 200 series chipset which is incompatible with 8th gen cpu.
I have the Inspiron 3277 AOI. The SSD went bad and it could not be repaired. I put in new SSD, created the recovery USB using the tool from Dell website. The machine recovery first installed Windows10. Once everything was working, I attempted to upgrade it to Windows 11 but the healthcheck said the I3 CPU did not meet the condition. Few days later, the system crashed after some windows 10 updates. I had to do the recovery again, this time , upon coming in the recovery screen, I had option to install Windows 11. The process went very smooth, directly from Microsoft, no bypass or anything to that regard.. Windows 11 has been working beautifully for 4-5 days now, The machine has the motherboard 025M63. The machine specs said this can have max 16 GB DDR4 SODIMM RAM. It had 8GB stick to begin with. I bought a 16GB and put it in thinking I would max it out the RAM. However, I decided to leave the original 8GB in there, machine boot and has been working fine. I can see 24GB installed RAM and 23.9 useable. I am planning to add another 16GB to see if it would take it. Do you think we normally can go more than what the specs said? So far, no crash, machine is very fast considering it is at least 2018 model. Thanks
It's not too unusual for some older/somewhat older Dell's to exceed max spec RAM. Not 100% sure if the 3477 can run 40GB RAM. May be another 8GB for 32GB total?
I added another 16GB stick today. Both msinfo32 and Task Manager can see installed 32GB RAM and 31.9 GB usable RAM! It has been about 7 hours since I installed with, doing some normal browsing and playing some games, so far, everything is fine and smooth and ...super fast! This make me wonder how much RAM this can go. For the fun of it, I am thinking about trying 2x32GB to see if it can take them. Will post some updates soon.

If the RAM doesn't work, it simply won't boot.
Can always check out userbenchmark Inspiron 3477 to see what others are using.
