Unfortunately no for 2 reasons. You do not have TPM 2.0 and you cannot update to TPM 2.0. Secondly and more importantly, you have a 4th generation Intel CPU and Windows 11 requires an 8th generation Intel CPU or better.
My wife's computer is the inspiron 3847. I have just read that windows 11 will require TMP2.0. Does anyone know if this model has it or if it can be added easily.  The computer runs windows10 perfectly since I replaced the HD with a SSD but we don't won't to waste time or money for a new computer because she is very happy with what she has.  Any advice is welcome. Thanks in advance.
