There are a lot of older laptops out there that are used for only one thing, web surfing. The old integrated graphics may play some older games but that is the extent of it.
Windows 10 is available up the end of 2025. After that you will need to get a new laptop or install Linux.
Recent Intel and AM4 are TPM 2.0 compliant. Desktop users are not worried but laptop users will need to fin new rigs in the nest 24-36 months.
Given there are hundreds of millions of laptops that are not TPM 2.0 capable mean vast numbers of machines will be out of work. I use Linux on an old Lenovo laptop with a SSD to host the website. The machine is SATA III speed which means SSD can reach 8TB before the machine has to be replaced, The Lenovo machines in the studio are older T400, T500, X220 and X230.
Discrete TPM units for desktop machines will be ramped up given the increased demand. The industry is ramping up production to handle the new demands. Generally each motherboard has a varying number of pins to force users to buy their corresponding TPM device. Some headers are 2×6 pin, some are 2×10 so they are not interchangeable.

Linux is now rich with software. The open source nature means it can be maintained by disparate developers as needed. The desktop has swerved all over as new ideas surface.
