I cannot change turn on optional diagnostic data to update Windows Insider Program even though I am the the sole owner, administrator and only user on my personal computer of my small business. Up until now I have had no problems updating my Windows Insider Program software. Now, even though I am able install system updates, I have been unable to 'update Insider' and continue to receive notices regarding the need to update.

"This build of Windows will expire on 8/11/2026"

  • Error message: "Your organization prevents sending optional diagnostic data to Microsoft, which means you won't get Windows Insider builds. Contact your organization's support person for more info."
  • Windows 11 Insider Preview Quality Update (26300.8935) update installed 7/22/2026
  • The last successful update was Windows 11 Insider Preview Feature Update (26300.7674) on 1/29/26

Hello Bonnie-Jo

The simplest fix for issues with anything under the WindowsSelfHost Registry Key is to simply delete the entire WindowsSelfHost Key. It will be rebuilt.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost

Copy the following to notepad and create a file called update.txt:

net stop wuauserv

net stop cryptSvc

net stop bits

net stop msiserver

ren C:\Windows\SoftwareDistribution SoftwareDistribution.old

ren C:\Windows\System32\catroot2 Catroot2.old

net start wuauserv

net start cryptSvc

net start bits

net start msiserver

Now rename the file to update.bat, and run the batch file as administrator.

As for the registry entries, there are technically two different locations depending on how the settings are applied.

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DataCollection is the location the AllowTelemetry value is set if it is configured by policy (i.e., InTune, ConfigMgr, Group Policy, etc.)

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\DataCollection is the location the AllowTelemetry value is set when you make a change via the UI

The first will have precedence over the second. If you have no entry in the first location (which consumer devices shouldn't), it means your device does not have a policy applied to that device for that setting from a management tool.There are four settings for diagnostic data: 

  • 0 – Security 
  • 1 – Basic 
  • 2 – Enhanced 
  • 3 – Full 

To participate in preview build flighting, it is required that a device be set to Full

    Windows Insider Preview builds require optional diagnostic data to be turned on. If that setting is blocked, the device will continue to show the message that the build will expire and Insider builds will not be offered.

    Use this check path first:

    1. Open Settings > Privacy & security > Diagnostics & feedback.
    2. Check Send optional diagnostic data.
    3. If it is Off, turn it On and restart the device.
    4. After restart, go to Settings > Windows Update and select Check for updates.

    If the setting cannot be changed and Windows shows “Your organization prevents sending optional diagnostic data to Microsoft”, that means the diagnostic data setting is being managed by an organizational policy on the device. On Insider devices, this blocks preview builds even if regular system or quality updates still install.

    Also verify these Insider requirements:

    1. Open Settings > Windows Update > Windows Insider Program.
    2. Confirm the device is still linked to the correct Insider account.
    3. Confirm the account used is the one registered for Windows Insider.
    4. If the device needs to use a different account type, the Insider account connection can be changed from Settings > Windows Update > Windows Insider Program after registering that account.

    Important points for this scenario:

    • Administrator access is required to change Insider update settings.
    • Optional diagnostic data must be enabled for Insider Preview builds.
    • If the current build is approaching expiration, go to Settings > Windows Update > Windows Update and select Check for Updates after fixing the diagnostic data setting.
    • If updates still are not offered after that, Microsoft’s Insider troubleshooting guidance says a clean installation of Windows might be required. This is a higher-risk step because it can reset the device and may require reinstalling apps and restoring data.

    Because the device is already receiving standard updates but not Insider builds, the blocked optional diagnostic data setting is the key issue to resolve first.

    I was unable to access "Computer Configuration > Administrative Templates > Windows Components > Data Collection and Preview Builds". I have attempted all the steps above and was still unable to change the Diagnostics & feedback setting. I continue to experience the issue of not being able to update Windows Insider Preview builds.

    I'm now wondering if I need to perform a clean install. If I do, will I still be able to participate in the Windows Insider program and will it automatically update then?
