Alt tab not working

#1 · 18/07/2026, 07:33

My setup is a desktop pc as the host, then a laptop as the viewer and keyboard, both connected via an ethernet cable between each other. Before now, alt tab done on the viewer keyboard was received by the host properly, now its received by the laptop instead but still sends alt to the host desktop in a way where it cannot be unpressed until the viewer presses it again(although this seems inconsistent). I’m not sure if there was an update or what but I don’t use the laptop for anything other than Spacedesk so not much varies in what’s running or what’s updated, my last Windows update was about a week ago, and my last Spacedesk viewer restart was about when this issue started. I’ve tried to find an old version of the viewer but couldn’t find anything besides one of my old installers that just redirects to the Microsoft store.

Hi @ethonic,

Which Windows Viewer are you using, the Windows Store version or the Legacy Version downloadable from the spacedesk website? I wasn’t able to reproduce the issue on my end, Alt-Tab works fine with both versions of the Windows Viewer.

Hi @martin-20,

The issue has been reproduced and was forwarded to our developers. In the meantime, you may use the spacedesk Legacy Viewer available for download in the spacedesk Downloads page. Thank you.
