The biggest bottleneck is the hard drive -  Windows 10 and 11 do much better with a native SSD. A lot of those Dell services are consuming quite a bit of memory.  If you're not using them, shut them down.  Given the slow primary storage and therefore slow virtual memory, it should help appreciably.  
hello please help me! My dell Inspiron is running too slow and the fan has high sound especially when the device is plugged into the charger,  note - the laptop was running well when I bought it even I was using heavy programs such as photoshop and illustrator it was running well/ but now I am just using chrome and this stuff without using any programs and still running too slow note -I am not loading on the storage thus this isn't a reason thanks in advance 
My Dell Inspiron 15 3593 is very slow!
