Common questions
What does the cbdhsvc service do?
A per-user service. Microsoft says Windows uses it for clipboard scenarios, and gives clipboard history and sync across devices as examples. Windows creates it from a template when you sign in and deletes it when you sign out. It runs C:\Windows\System32\svchost.exe (svchost.exe -k ClipboardSvcGroup -p) as The signed-in user.
Can I disable cbdhsvc?
Depends on what you use. Microsoft's guidance for fixed-purpose Windows 10 and 11 IoT Enterprise devices rates it OK to disable. If you use clipboard history or clipboard sync, leave it; if you only want those features off, switch them off in Settings and leave the service alone. We know of no published measurement showing a speed benefit from disabling it.
Why does the name end in random characters, like cbdhsvc_67db3c?
Microsoft documents that Windows shows every per-user service as the service name followed by an underscore and a locally unique identifier for the user context, and that the display name carries the same suffix. The suffix differs between PCs and sign-ins; it is not a sign of malware.
How do I turn off clipboard history without touching the service?
Open Clipboard settings in the Settings app and turn off Clipboard history; the same page has the switch for syncing the clipboard across your devices. Microsoft's clipboard help page describes both.
How do I check that it is the real service?
On Windows 11 build 26300 the template is registered as svchost.exe -k ClipboardSvcGroup -p and loads C:\Windows\System32\cbdhsvc.dll, signed by Microsoft Windows; the instance for the signed-in user was running. tasklist /svc /fi "services eq cbdhsvc*" shows the svchost.exe process that hosts it.
