Windows 10’s automatic maintenance feature is one of the features Microsoft uses to keep your PCs in tip-top shape. Microsoft typically runs all maintenance features once a day, a time it determines you aren’t actively using your PC, though if you’re on your PC 24/7 or you shut your PC off to save battery, it’s possible for you to miss a cycle.
In a maintenance cycle, Microsoft typically runs disk optimization – including defragmentation and scans for malware as well as app and system updates. It would typically run for an hour a day, and maintenance tasks can only run within this hour unless it’s a critical task. This means that they would stop working if they are interrupted. Typically, you can expect it to run between 2 AM – 3 AM local time.
Microsoft offers you options for customizing this which we’ll run through shortly. However, to disable the automatic maintenance feature, you’ll have to go a little more hands-on and delve into the registry editor itself.
Here’s how to control Windows 10’s automatic maintenance cycle
• Launch the control panel app.
• Navigate to System and Security > Security and Maintenance.
• In Maintenance, expand it to find the “Automatic Maintenance” Settings
• Under the Select Maintenance Settings, click on it and use the “Run maintenance tasks daily” menu to select what tie you want Windows to run your maintenance tasks.

• To disable it entirely, (should you want to for whatever reason), Open the Registry Editor by typing regedit into Cortana/Search and copying and pasting this into the address bar if you’re on the Windows 10 Creators Update and above: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\Maintenance
• Create a new key with the “DWORD 32-Bit” value and name it MaintenanceDisabled.
• Change the value from 0 – 1.

• To revert the change, repeat steps 5 -7, but change it back to 0 instead.
