This has been a source of irritation for many recently. Simply disabling wake timers and disabling the Windows Update service is no longer enough to keep Microsoft from waking your machine from sleep mode to carry out maintenance and install updates. It looks like this was introduced as an update sometime in 2018 and affects Windows 10 1607, 1703 and 1709. Fortunately there are a number of steps you can take to stop Microsoft meddling with your machine and leaving it running all night costing you larger electrical bills.
The Windows 10 Fall Creators Update is nearly upon us as summer rapidly draws to close. Like 1511, 1607 and 1703 before it the current build of 16241 or ‘Redstone 3’ has been available as a preview to insiders (in this case since April 14, 2017).
Problem: The Microsoft .NET Framework 3.5 (which is required for many applications) won’t install via ‘Programs and Features’, ‘Turn Windows Features on or Off’. You may get errors 0x800F0906, 0x800F081F, or 0x800F0907.
