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.

To understand why hibernation can cause performance degradation over time, it helps to know how it works. When you hibernate, Windows writes the entire contents of RAM to a file on your hard drive or SSD. This includes all open programs, documents, system state, and even kernel memory. Upon resuming, it reads that file back into RAM. Over multiple hibernation cycles, the system state accumulates transient errors, memory leaks from applications, and background processes that may not fully clear until a complete shutdown occurs. These small issues compound, leading to the slowdowns many users experience.

Another factor is the way Windows manages memory during hibernation. The operating system preserves parked memory pages that may contain corrupted or outdated data. Although Windows tries to maintain integrity, the lack of a fresh boot means temporary glitches—like driver hiccups or registry caches—persist. This is why a full shutdown is often recommended as a troubleshooting step for mysterious performance issues.

Additionally, the size of the hibernation file, hiberfil.sys, is typically set to about 75% of your total RAM. For systems with 16GB or more of RAM, that file can occupy 12GB or more on the boot drive. While SSDs are larger today, every gigabyte matters, especially on devices with limited storage like ultrabooks or tablets. Disabling hibernation can reclaim that space immediately.

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.

Beyond the subjective feeling of freshness, there are measurable benefits to daily shutdowns. For example, Windows clears the system cache, closes all background processes, and resets the memory allocation. This helps eliminate memory fragmentation that can slow down applications over time. Also, any pending file operations or temporary locks are resolved, reducing the chance of file corruption. For users who run resource-intensive tasks like video editing or gaming, a fresh boot can improve performance by freeing up resources that were held by background services.

Moreover, regular shutdowns extend the lifespan of some hardware components. SSDs, for instance, have a finite number of write cycles. While hibernation writes a large file each time you enter that state, shutting down does not—it simply powers off without additional write operations. Over years of use, this difference can be significant, especially for older SATA SSDs with lower endurance ratings.

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.

So 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, then click “Change settings that are currently unavailable” and uncheck “Turn on fast startup (recommended)”. After that, every shutdown becomes a true full shutdown, ensuring the system resets completely. The trade-off is a slightly longer boot time—usually only a few seconds on modern SSDs—but the improved stability is well worth it.

For users on NVMe SSDs, the boot time increase is often negligible, often under five seconds. On older hard drives, the difference might be more noticeable, but even then, the benefit of a clean state outweighs the small delay. Many enterprise IT departments mandate disabling Fast Startup to maintain system integrity across workstations.

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 is part of Windows 10 and 11’s “Restart Manager” which allows applications to register for automatic state preservation. When enabled, the operating system notifies apps before shutdown and gives them a chance to save their state. After reboot, those apps are relaunched and given the saved state. This bridges the gap between the convenience of hibernation and the cleanliness of a full shutdown.

For apps that don’t support restartable apps, you can still manually save your work before shutting down. Browser sessions can be preserved by enabling the “Continue where you left off” option in settings. Many productivity apps like Microsoft Office also offer auto-recovery features. The key is to develop a routine that combines shutdown discipline with smart saving habits.

Another useful tool is the “Group Policy” setting for automatic restart after updates—configuring active hours can prevent forced restarts during work time. Also, using Task Scheduler to automate a nightly shutdown at a set time ensures you never forget. Simply create a basic task that runs the shutdown /s /t 0 command at midnight or whenever you finish your day.

Ultimately, the decision between hibernation and shutdown depends on your usage patterns. If you rely heavily on many open programs and quick resume, hibernation still has its place. But for the average user seeking a stable, responsive system, nightly shutdowns—combined with disabling Fast Startup and leveraging restartable apps—offer a clear advantage. The initial inconvenience of reopening a few apps fades quickly once you experience the consistent performance day after day.
