Is there a software that tells me what I can do with everything and with which I can upgrade / equip my laptop?
No, but we can help you with that.
Most laptops can only upgrade Ram and Hard Disk / SSD. Which model do you have exactly?
MODEL. Pro7aj
You can expand Ram, need DDR3 SoDimm, and install an SSD, the standard 2.5 "format.
Everything else is not possible, just a laptop. ^^
Ram or hard drive and possibly Wi-Fi or GSM module, nothing works…
This is an insufficient name. The manufacturer would have been nice.
But what is Google for? Ok, the device is from Asus.
But with the model designation still missing a letter at the end: U, T, R, or K. There are according to Asus support several variants.
But you can also let your notebook innards shine through:

Ne is not there because laptops are actually not upgradable otherwise we can certainly help you further but I think Ram can always be upgraded to laptops but then you have to buy special
