I have a Lenovo x230 laptop that I've been using for years. In the past week or so it has slowed down to an amount that is challenging my patience, no matter what the function from booting to browsing. It seems to have to do with a recent update to windows, but I can't tell. Task manager doesn't show excessive CPU use. I have kept up with all the Lenovo system updates and system is current.
Windows 10 pro build 17134, 64 bit
System Model 23252 VU
16 Gig Ram
Samsung SSD 500 gb
What should I be looking for?
