I had a little complain on Twitter about this:
I really miss the old #Windows calc; the new app is really slow to load and doesn't have the functionality (thinking history).

My friend and fellow MVP, Steve Endow suggested a solution as a replacement to the new Calculator app:
Well, Steve played canary for me and installed the Old Windows Calc app from Winaero without issue, so I figured I could give it a go myself.
The app is fairly simple to install and appears to work well.
It appears on the Start menu; for me it is the second app and is the default app when using Win+R and typing calc.
I am going to continue testing this over the ext few days to see how well it works over a more extended period of time, but first impressions are positive.
