• Windows Update assumptions are often changed indirectly by updates, policy, hardware changes, or cleanup work that looked harmless at the time.
• Intune assumptions are often changed indirectly by updates, policy, hardware changes, or cleanup work that looked harmless at the time.
• Policies assumptions are often changed indirectly by updates, policy, hardware changes, or cleanup work that looked harmless at the time.
