My notebook an i5 CPU 3rd generation from 2013 needs 5 seconds to save / update an Excel spreadsheet, why so long?
How long have you got the operating system on your PC? Has that been updated?
No more has been done since 2013.
You can probably upgrade and install a SSD. If there's a HDD in it is probably pretty lame
There's already a 1 TB SSD in it.
It's no wonder.
Do you have Window 7 on it?
No Win 10… And yes, updates have been made!
How complex is the Excel spreadsheet?
Very simple basic arithmetic operations.
I'm not capable of more.
