Hi Mallesh,

Do you mean you applied the Desktop RDP settings color depth etc? Follow this link - https://learn.microsoft.com/en-gb/windows/win32/w8cookbook/desktop-window-manager-is-always-on?redirectedfrom=MSDN

Kind of similar issue but within Citrix this was very frequent on our servers - https://support.citrix.com/article/CTX200082/error-the-desktop-window-manager-has-exited-with-code-0xd00002fe-when-launching-apps-and-desktops

Hope this helps.
