Thanks,
The lag is probably more due to accumulated OS updates and junk. An in-place upgrade (even to W7) would probably speed it up no end as this clears out a lot of junk and set most of the registry back to defaults.
As for performance, it's a higher spec machine than my System One in My Computers below (I do have more modern higher spec machines, but there's only room for two system in my specs ).
It has the same speed and size of RAM (DDR3, 1333Mhz, 4GB), but it's cpu has a higher spec. That model came with either a 2nd gen. Intel Core i3 or i5. The entry level cpu for that machine was an Intel Core i3 2330M, which has a benchmark better than my Pentium B950, 2526 vs, my 1716. I'm perfectly happy with the performance of mine running 1903, Windows 10 runs better on it than Windows 7 ever did. That Inspiron should be up to the job too.

Like mine, it came originally with 64-bit Windows 7 Home Premium. It also had MS Office 2010 pre-installed (but not activated). If that was purchased and activated then Office will be retained on upgrading to W10. If the free Office Starter 2010 was activated instead, then the upgrade will remove it as Office Starter 2010 is deemed by MS incompatible with W10. The Media Center that was included in W7 Home Premium will also be uninstalled.
