Dell is not going to test the Inspirion 3552 for the Windows 11 upgrade. I know the Processor I currently have isn't supported by Windows 11. According to the PC Health Check that I ran that is the only problem I have. The processor has 2 cores (2 or more required) and the processor clock speed is 1.6 GHz (1 GHz or faster required). My question is: can the processor I currently have installed be replaced with one of the supported CPU's or do I just simply keep using Windows 10? Please I don't understand the generation 8 etc. I'm not a computer geek. I lost her when I retired and now am in limbo. Thanks in advance!
