Since changing how I work, which means I am more reliant on my laptop’s own screen, I found that the vertical scroll bar was a bit narrow for my liking, and my mouse often wavered off it in use and accidentally clicked on something else.
To my surprise, in Windows 10, there is no control for the scroll bar width (at least not that I can find). In Windows 7, it was directly controlled by one of the Advanced screens in the control panel. I would have thought it would be a prime contender for an entry in Windows 10’s Ease of Access controls, but no.
So a bit of Googling, and the answer is to change it in Regedit. I think it is poor that the setting is not more accessible.
I now have ScrollHeight and ScrollWidth set to -400. This is totally over the top, but I like it. The default is -225, so I reckon -300 is probably a more subtle widening.
Note: not all programmes use the Windows settings unfortunately. Poor show, Slack!
