Why does itunes open so slowly on Windows 10?

I had the same issue until I stumbled on the solution mentioned here: https://answers.microsoft.com/en-us/windows/forum/all/itunes-takes-at-over-9-minutes-to-load-on-windows/4848cc42-0536-4263-a633-90824471d239

I see you’re using the Microsoft Store version of both iTunes & iCloud. I found the same problem with the store versions so I downloaded the versions from the Apple website & these open quickly. They’re the same version as the store’s.

I would uninstall using Revo Uninstaller>Uninstall Apps https://www.revouninstaller.com/products/revo-u... & once completed then run the scan for leftovers then install the Apple version from here:

http://updates-http.cdn-apple.com/2020/windows/... This is the direct link to iCloud download.

I was worried that if I do this my library will be gone, especially after scanning for registry leftovers. Thankfully everything was exactly the same when I opened iTunes the first time after re-installing it. Now iTunes opens in 2-3 seconds.
