Give it time, my 2008 lenovo was originally marketed as a "photoshop-workstation". Now it chugs to even boot any Windows operating system that takes updates.
I would recommend cleaning the contact points on the CPU and heat sink. The thermal compound disintegrates over time, the fan and any intake/exhaust ports should be cleared.
My 2011 XPS 17 was struggling to boot and running full fan on idle, after I took it apart and cleaned it, it improved significantly.
Edit: struggling to run efficiently and satisfactorily fast.
give it a break, it is a decade old! my x1 carbon is 5 years old and while it handles the majority of day to day tasks its starting to feel its age now, hopefully the x1 extreme will carry me through another 5 years
