Will ReadyCache have a driver for Windows 10?

Today I upgraded my fathers PC from Windows 7-64 to 10, which had been speeded up by the readycache. Despite the upgradeprocess mentioning nothing about the readycache it is not working after the upgrade.

There is no way to (un)install it. I tried erasing files and the registry as directed in a post, but still the procedures complain about an existing newer setup or 1.3.2 not being able to continue.

Should I downgrade and wait for a solution?
