AVD clipboard redirection broken after 5/12/2026 updates — rdpclipcdv.exe present but not functioning

Jacob Winkhaus 0 Reputation points

Clipboard redirection stopped working on our Azure Virtual Desktop (Azure Government) session host after automatic updates installed on 5/12/2026 (KB5092762, KB5089549, KB5087054).

Environment:

  • Host pool: personal, Windows 11 Enterprise multi-session 24H2, build 26100.8457
  • RDInfra SxS version: 1.0.2512.08200
  • Windows App client: 2.0.1186.0

What we've verified:

  • redirectclipboard:i:1 explicitly set in host pool RDP properties
  • GPO "Do not allow clipboard redirection" = Not configured
  • AppLocker = AllowedByDefault for rdpclipcdv.exe
  • Defender exclusion added for rdpclipcdv.exe
  • rdpclipcdv.exe is present and shows as running (3 instances)
  • Issue persists across Windows App, web client, and legacy web client
  • VM restarted, session fully disconnected and reconnected

Clipboard worked at initial deployment. Stopped working after the 5/12 updates. Drive redirection works fine.Clipboard redirection stopped working on our Azure Virtual Desktop (Azure Government) session host after automatic updates installed on 5/12/2026 (KB5092762, KB5089549, KB5087054).

    Following the troubleshooting steps from the responses above, here is where we stand:

    Completed:

    • Verified rdpclipcdv.exe and rdpinputcdv.exe are both running (2 instances each, one per active session)
    • Confirmed clipboardblockeddatatypes is not set in host pool RDP properties
    • clipboardredirecttypes:i:63 is set (all data types allowed)
    • Added Defender exclusion for rdpinputcdv.EXE at full path C:\Program Files\Microsoft RDInfra\rdr_sxs\1.0.2512.08200\rdpinputcdv.EXE
    • All 7 RDInfra executables are AllowedByDefault in AppLocker
    • GPO clipboard redirection policies confirmed not configured
    • Tested fresh session after exclusion — clipboard still non-functional

    Virtual channel check: Win32_TSVirtualChannel WMI class returns InvalidType — appears unavailable on Windows 11 multi-session, so unable to validate clipboard channel establishment via that method.

    At this point all recommended configuration checks have been exhausted. Clipboard worked prior to the May 12 updates and has not worked since. Is there a known hotfix or servicing update targeting clipboard regression on Windows 11 Enterprise multi-session 24H2 with RDInfra SxS 1.0.2512.08200?

    Hi Jacob Winkhaus

    Based on what you’ve described, the clipboard redirection issue looks tied directly to those May 12th cumulative updates (KB5092762, KB5089549, KB5087054). We’ve seen similar behavior where the update introduces a regression in the rdpclipcdv.exe process, even though it’s running and allowed by policy. Since drive redirection is still fine, that narrows it down to clipboard-specific handling in the patched binaries.

    The quickest way to confirm is to temporarily roll back one of those updates (start with KB5092762 since it’s the core cumulative) and retest clipboard. If that restores functionality, you’ve got your smoking gun. Another workaround some customers have used is manually restarting all rdpclipcdv.exe instances after logon not pretty, but it can get clipboard moving again until a hotfix lands. Also worth checking if Microsoft has released a servicing stack update or preview patch that addresses clipboard regression on 24H2 builds; those tend to follow within a couple weeks of a breaking cumulative.

    I’d recommend opening a support case if rollback isn’t viable, since this looks like a product bug rather than a config issue. In the meantime, keep an eye on the Azure Virtual Desktop release notes and Windows 11 cumulative updates for any mention of clipboard redirection fixes.

    Hello Jacob,

    Thank you for the detailed information and troubleshooting steps you've already completed. This significantly helps narrow down the possible causes. Based on the environment details provided, the issue appears to be related to the clipboard redirection component used by newer Azure Virtual Desktop session hosts.

    Microsoft introduced additional clipboard and input channel components in newer RDInfra SxS Network Stack releases, including rdpclipcdv.exe and rdpinputcdv.exe, which are responsible for clipboard redirection and related functionality. Since your environment is running RDInfra SxS version 1.0.2512.08200, these components are actively involved in clipboard channel negotiation.

    While the presence of multiple running instances of rdpclipcdv.exe confirms that the process is launching, it does not necessarily indicate that the clipboard virtual channel has been successfully established. Based on the behavior described, the issue may be occurring during clipboard channel initialization or negotiation.

    To further isolate the cause, we recommend the following checks:

    1. Verify both clipboard-related executables are fully allowed

    Please confirm that any security controls, including AppLocker, Microsoft Defender, Defender for Endpoint, or any third-party endpoint protection solution, allow both of the following executables:

    • rdpclipcdv.exe

    rdpinputcdv.exe

    Additionally, verify that any exclusions apply to the full installation path under the RDInfra agent directory and not only to the executable names.

    You can validate that both processes are running by executing:

    Get-Process rdpclipcdv, rdpinputcdv | Select-Object Name, Id, Path, StartTime
    

    It would also be helpful to review AppLocker and security-related event logs around the time a user session is established.

    1. Review Host Pool RDP Properties

    Please review the Host Pool RDP Properties and verify whether the parameter below is present:

    clipboardblockeddatatypes:s:
    

    If configured, temporarily remove it and test again to rule out restrictions on specific clipboard data formats.

    1. Validate the Clipboard Virtual Channel

    From within an active AVD session, please check whether the clipboard virtual channel is successfully established:

    Get-WmiObject -Namespace root\cimv2\TerminalServices -Class Win32_TSVirtualChannel | Where-Object { $_.ChannelName -like "*clip*" }
    

    If the clipboard channel is absent or not connected, this would indicate a channel negotiation issue rather than a process startup issue.

    1. Review Relevant Event Logs

    Please review the following logs for any warnings or errors occurring during session connection:

    Applications and Services Logs → Microsoft → Windows → AppLocker

    Applications and Services Logs → Microsoft → Windows → TerminalServices

    Windows Logs → Application

    Particular attention should be given to events referencing RDInfra components, clipboard redirection, virtual channels, or process initialization failures.

    1. Test with a New User Profile

    If possible, create a new test user profile and establish a fresh session. This helps determine whether the issue is tied to a specific user profile or session state.

    Based on the timeline provided, we also note that the issue began immediately following the May 2026 update cycle. While we cannot conclusively attribute the behavior to a specific update at this stage, the timing suggests that a recent platform or operating system change may have contributed to the issue.

    If the above checks do not identify the root cause, we would recommend opening a Microsoft Support case for deeper investigation and referencing the observed behavior on Windows 11 Enterprise multi-session 24H2 with RDInfra SxS version 1.0.2512.08200. This will allow the engineering team to determine whether a known issue or regression is involved.

    Please let us know the results of the above checks, and we will continue working with you on the investigation.

    Based on the environment and checks already done, the scenario matches the known SxS Network Stack behavior where clipboard and window-resizing features depend on new RDInfra executables that can be blocked by application control or security tooling.

    Even though rdpclipcdv.exe is present and shows as running, clipboard redirection can still fail if any of the required RDInfra executables are blocked or not fully allow‑listed in all their possible paths.

    Perform these checks and changes on the session host:

    1. Confirm all required RDInfra executables are allow‑listed Ensure the following executables are explicitly allowed by any of these controls in the environment (SRP, AppLocker, third‑party endpoint protection, Defender controlled folder access, etc.) when executed from subfolders of C:\Program Files\Microsoft RDInfra:
      • rdpinit.exe
      • rdpshell.exe
      • rdpstartup.exe
      • rdpstartuplauncher.exe
      • rdpvchost.exe
      • rdpclipcdv.exe
      • rdpinputcdv.exe
      Do not only allow‑list rdpclipcdv.exe; all of the above must be allowed or clipboard initialization can fail.
    2. Re‑check Group Policy and Intune redirection settings The most restrictive setting wins across OS, host pool RDP properties, Intune, and GPO:
      • Host pool RDP property redirectclipboard:i:1 is already set.
      • Confirm there is no Intune or additional GPO that disables clipboard or drive redirection for these hosts or users. If drive redirection is disabled via Intune/GPO, file transfer via clipboard is blocked even if text/images are allowed.
      • In GPMC, verify on the session host OU:
        • Computer Configuration > Policies > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Device and Resource Redirection > Do not allow Clipboard redirection is Disabled or Not configured.
    3. If using new directional clipboard controls, verify they are not over‑restrictive On Windows 11 multi‑session with recent cumulative updates, additional clipboard direction policies may be present:
      • Restrict clipboard transfer from server to client
      • Restrict clipboard transfer from client to server
      In GPMC under the same Device and Resource Redirection node, ensure that if these are Enabled, they are configured to allow at least the data types being tested (for example, “Allow plain text” or “Allow plain text and images”) in both directions as needed.
    4. Refresh policy and restart session hosts After adjusting allow‑lists and GPO/Intune settings:
      • Run gpupdate /force on the session host.
      • Restart the VM to ensure RDInfra and RDP services initialize with the updated policies and allow‑lists.
      • Test clipboard redirection again from a fresh session (not a reconnected one) using simple text first.

    If clipboard redirection was working before the 5/12 updates and stopped immediately afterward, the most likely root cause is one or more of the RDInfra SxS executables being blocked by application control or security tools after the updated binaries were deployed. Ensuring all seven executables listed above are fully allow‑listed from C:\Program Files\Microsoft RDInfra and that no stricter GPO/Intune setting is applied should restore clipboard redirection.
