Windows 10 Tech Preview Fails Windows Update, Hangs on Update, Etc.

If you are currently using Windows 10 Build 9926, you may experience issues attempting to upgrade to build 10041 (10049). Some common issues experienced are as follows:

Windows Update does not see any updates available, and says everything is up to date.

In order to try to resolve this issue above, you should attempt the following:

  • Open regedit.exe (run as Administrator)
  • Go to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost\Applicability
  • Ensure the following values/keys exist (and delete any others):
    • BranchName, REG_SZ, fbl_impressive
    • ThresholdRiskLevel, REG_SZ, high
  • Delete all other values/keys.
  • Open Settings > Update & recovery > Windows Update
  • Tap or click Check for updates (Windows should now start downloading updates, including build 10041 or >)

Installing Windows 10 Technical Preview Upgrade Appears to Hang @ 2%, and 3%.

Try to be PATIENT, as this is a known interval, and is not uncommon to take 10 minutes or > for progress to show/move). (However, if installation hangs, for more than an hour or 30% there may be other issues. This is still under investigation.










After Windows 10041 install or upgrade you find that Mail, Calendar, and the People tiles no longer function, work, and are broken.

    • Microsoft recommends users attempt the following to resolve this issue
    • Run/Open PowerShell as Administrator. (Open TaskManager, eg. press CTL + R and then type taskmgr), when it launches select launch new application from the menu, type “powershell” and check the box to run with Administrative Privileges.
      From within powershell, paste the following:Get-appxprovisionedpackage –online | where-object {$_.packagename –like “*windowscommunicationsapps*”} | remove-appxprovisionedpackage –online
    • Then, reinstall Mail, People and Calendar from the Store (the non-beta version).
