Microsoft has been modifying windows 7 & 8 with their 'telemetry' that's part of 10, and also pushing 10 on users of 7 & 8. I keep seeing the 10 update in Windows Update, even though I've hidden it and uninstalled the Get Windows 10 tool (KB3035583). Telemetry is sending data back to Microsoft about how you use your computer. If, like me, you're uncomfortable sending unknown data back to Microsoft, you can do the following. Below are the best instructions I've found so far. If it looks like Geek to you, call your IT person, but most of it is quite simple, although windows does its best to hide Task Scheduler and Services. Remove the following updates (if installed already) KB3068708 Update for customer experience and diagnostic telemetry KB3022345 Update for customer experience and diagnostic telemetry KB2952664 Compatibility update for upgrading Windows 7 KB2990214 Update that enables you to upgrade from Windows 7 to a later version of Windows KB3035583 Update installs Get Windows 10 app in Windows 8.1 and Windows 7 SP1 KB971033 Description of the update for Windows Activation Technologies KB3021917 Update to Windows 7 SP1 for performance improvements KB3044374 Update that enables you to upgrade from Windows 8.1 to a later version of Windows Command Prompt: sc stop Diagtrack sc delete Diagtrack *Task Scheduler Library: Everything under "Application Experience" Everything under "Autochk" Everything under "Customer Experience Improvement Program" Under "Disk Diagnostic" only the "Microsoft-Windows-DiskDiagnosticDataCollector" Under "Maintenance" "WinSAT" "Media Center" and click the "status" column, then select all non-disabled entries and disable them.
