Fix: Can’t join Windows Insider on Windows 10

FIX 1 – Using Settings app

The first thing you should do to fix this is check diagnostic data settings. Only if you’ve allowed telemetry, you should be able to join and receive preview builds from Windows Insider programme.

Try these steps:

1. Right click Start Button or press + X keys and select Settings.

2. In the Settings app, go to Privacy > Diagnostics & feedback.

3. In right pane of Diagnostics & feedback, make sure Optional diagnostic data is turned On. Also ensure that Improve Inking and typing and Tailored experiences options are set to On in this location.

Now retry joining Windows Insider programme, and see if it works.

FIX 2 – Using Registry

1. Run regedit command to open Registry Editor. 

2. In Registry Editor window, go to:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost

3. Right click on WindowsSelfHost registry key and select Delete. In the confirmation from appearing next, click Yes.

4. Close Registry Editor and restart your system to make changes effective.

After rebooting your system, you should be able to join Windows Insider programme on your Windows 10, as expected.
