richarddd Considering half of my office is still running Lenovo T540p laptops running a mix of Win7 and Win10 on them (max RAM, SSDs retrofitted), your X1 should be fine for quite some time. If you feel so inclined (not sure why you would), you can even run Windows 11 on your computer. Despite my office's laptops being 10+ years old, they still can run circles around much of what's for sale at Best Buy today. It all depends on your specs.

If it's doing what you need it to do, keep running it.
