For the last couple of years, I've been hibernating my PC almost every single day. And honestly, I love the convenience of it. Closing everything down across all my virtual desktops only to reopen it all the next morning never really made much sense to me. So yes, for the longest time, I rarely ever shut down or rebooted my PC apart from Windows updates.

But then I had to stop doing it because of what daily hibernating was doing to my PC. And honestly, I’m glad I did because shutting down my PC every night has ended up being a much bigger improvement than I expected.

Hibernating is convenient, but there are downsides

It saved time but caused other problems

Hibernation used to feel like one of those perfect features to me. It gave me the best of both worlds: no battery drain like a full shutdown, while still letting me resume work exactly where I left off, like sleep mode. For a while, hibernating my PC worked great. But then, I started noticing a pattern. Every 7 to 10 days, my PC would gradually start feeling slower and less responsive. Then eventually, things would get bad enough that the entire system would freeze out of nowhere and I'd have to do a hard reset. Unfortunately, that also meant losing unsaved work at times.

This wasn’t the only issue, though. The hibernation file itself can be pretty large because Windows essentially saves your entire system state to storage. In my case, it was close to 10GB when I checked the storage usage. That may not sound massive, but it’s still space that can be used for something else. More importantly though, modern SSDs have made hibernation far less essential than it used to be. Earlier, PCs used to easily take a minute or more to boot up. But that’s not the case anymore. In my case, my PC boots incredibly fast anyway, so I’m barely saving any meaningful time by hibernating. Sure, reopening apps takes some extra time, but I feel it’s worth it if it’s helping my PC run smoothly.

The accumulation of background processes and memory leaks over days is a known phenomenon. When you hibernate repeatedly without a full shutdown, the system retains kernel sessions, driver states, and cached data. Over time, this can lead to fragmentation in memory allocation and subtle driver conflicts. This explains why the PC gradually became sluggish and eventually froze. Modern operating systems, including Windows, are designed to reset memory and clear temporary caches during a full shutdown. Hibernation bypasses that reset, allowing small inefficiencies to stack up until they become noticeable.

Regular shutdowns solved a lot of little problems

It wasn’t as bad as I thought

Once I started shutting down my PC every night, those random slowdowns that used to creep in completely disappeared. I can confidently credit regular shutdowns for this improvement because I didn’t really change anything else about my setup. More importantly, my PC also felt cleaner and a bit faster than before. It’s hard to describe exactly, but Windows just felt “fresh” every morning. The reason for this is pretty simple. With hibernation, a PC never really gets the chance to fully shut down and reset itself. Everything from background processes to temporary glitches and memory usage just keeps carrying over day after day. Regularly shutting down the PC fixes that.

Another side benefit is that Windows updates became much less annoying once I started doing this. When I relied on hibernation, there were times when Windows would suddenly decide to force an update in the morning or even in the middle of the day while I was busy working. Now, updates usually install during shutdown instead, so they’re far less disruptive. Of course, I still rely on hibernation from time to time. It’s not a bad feature by any means. Any time I know I’ll need to jump back into a project and want everything as I left off, hibernation is still handy. But yes, I no longer treat it as the default option every single day.

Additionally, nightly shutdowns can extend the lifespan of hardware components. Constantly keeping a PC in a low-power state like hibernation still exposes components to electrical current and heat cycles, albeit reduced. A full power-off allows the system to cool completely and reduces wear on components like the power supply and motherboard. For users who keep their PCs for several years, this can make a meaningful difference in reliability.

Fast Startup can make shut down less effective

It blurs the line between shutdown and hibernation

Shutting down your PC doesn’t always mean Windows is doing a full shutdown. That’s because Windows has a feature called Fast Startup enabled by default. During a shutdown, this feature saves part of the system state to disk, so Windows can quickly reload it during the next boot. In a way, it’s almost like a lighter version of hibernation. While faster boot times sound great, it also prevents your PC from fully shutting down and clearing bugs or memory issues. It simply reduces the effectiveness of a shutdown. Since parts of Windows kernel sessions are still being preserved, some underlying issues simply carry over between sessions.

To avoid this, I’ve also disabled Fast Startup on my PC, and it’s something I recommend to most people. Instead of relying on that, I’ve done other optimizations, like managing startup apps and disabling unnecessary background services. Disabling Fast Startup is straightforward: go to Control Panel > Power Options > Choose what the power buttons do > Change settings that are currently unavailable, then uncheck “Turn on fast startup.” After a full shutdown, the next boot may be a few seconds slower, but the trade-off in system stability and cleanliness is well worth it.

Windows restarts most of my apps after a shutdown

One of the things that made shutting down my PC regularly much more convenient for me is Windows’ restartable apps feature. It basically allows Windows to restore supported apps as soon as you sign in after a shutdown or reboot. To enable it, head to Settings > Accounts > Sign-in options and turn on Automatically save my restartable apps and restart them when I sign back in. Not every app supports it, unfortunately, but the ones that do work great. For me, it restores my Edge tabs, File Explorer folders, Notepad, and other supported apps exactly as I left them.

This feature bridges the gap between the convenience of hibernation and the cleanliness of a full shutdown. By combining nightly shutdowns with restartable apps, users can enjoy both a fresh system state and a quick return to their workflow. It’s worth noting that some third-party apps also offer similar restore functionality through browser session managers or system utilities. Over time, more applications are adopting this Windows API, making the experience seamless for productivity-focused users.

For those who are concerned about losing work or having to reopen many programs, this built-in Windows feature alleviates that worry. The transition from hibernation to shutdown becomes almost painless. Moreover, users can also use task scheduler to automatically close and reopen specific programs, or rely on the built-in startup folder to launch essential applications after login. This approach not only keeps the system stable but also maintains a consistent working environment.

In summary, while hibernation remains a useful tool for specific scenarios, making nightly shutdowns a habit can significantly improve PC performance and reliability. The combination of disabling Fast Startup and leveraging restartable apps maximizes the benefits without sacrificing convenience. As SSDs continue to shrink boot times, the argument for hibernation weakens, and the case for regular shutdowns grows stronger.
