  1. Using Windows key + R, open the round dialog, enter mstsc.exe, then click OK. 1649477309_307_Computer-cant-connect-to-remote-computer-security-package-error

This is used by the mstsc.exe client to load screen components from the local disk cache that haven’t changed since the previous rendering. The caching mechanism in RDP decreases the amount of data delivered across the network.
