Why restarting your computer matters more than you think
The single most common alert I see is a machine that hasn't been restarted in weeks. Here is why that matters.
If you are a monitored client, one of the alerts I see most often is device uptime. It means your computer has been powered on, or asleep, without a proper restart for a long stretch. Sometimes weeks. Occasionally months.
It is rarely dramatic, but it is behind a surprising number of the "my PC has gone really slow" calls I take.
What uptime actually measures
Uptime is the time since the last full restart. Shutting the lid on a laptop, or clicking Shut down on a Windows machine with Fast Startup enabled, often does not reset it. The machine hibernates the core of Windows and picks it back up in the morning, along with everything that was wrong with it the night before.
That is why a device can show 40 days of uptime even though the user "turns it off every night".
Why it causes problems
- Memory that applications never released stays claimed, so the machine gets progressively slower through the week.
- Windows and application updates sit in a pending state and cannot finish until a restart happens.
- Security patches that need a reboot are installed but not active, so the machine is protected on paper only.
- Background services drift into a failed state and stay there, which is what produces service alerts later.
- Printer, VPN and network oddities that "fixed themselves" almost always fixed themselves at the next restart.
How often should you restart?
Once a week is plenty for most people. Friday afternoon before you leave, or Monday morning before you start, is ideal. If your machine is heavily used, or if you have noticed it slowing down through the week, make it a habit at the end of each day.
The important part is choosing Restart, not Shut down. Restart always clears everything. Shut down, on many machines, does not.
What I do at my end
When an uptime alert comes in, I check the device, confirm nothing is running that would be lost, and restart it out of hours when nobody is signed in. You will usually see the result as a line in your monthly report rather than a phone call, because it is fixed before it becomes a problem.
If a device keeps generating uptime alerts, that usually tells me the user is closing the lid rather than restarting, and a quick word solves it permanently.
The short version
Restart once a week, properly, using Restart. It costs you two minutes and prevents a genuinely large share of everyday IT annoyances.
