My almost 8 yrs old lenovo notebook is running the 17763.55 (17763.1 then followed by 17763.55, via Windows update without fresh install), quite stable.
Nearly 8 yrs, i5-2410M 4GBx2 500GB hdd $5K+. Last year replaced with 240GB SSD. To be honest, the speed of that 2nd gen i5 is absolutely not slow (comparable to 5th/6th gen mobile i3). The worse part was, the battery died prematurely (in less than one year).
