RD Web not showing newly published RemoteApp programs

When we publish new RemoteApp programs OR we disable a RemoteApp program on one of the many servers in our RDSH farm, the RemoteApp program disappears from RD Web.

There is a hotfix available for that here:

After I installed it on my Windows Server 2008 R2 server running the RD Web role, it started working fine. It needs a reboot, though.
