When the typical Windows notification appears saying that updates are pending, many of us wonder whether to click "Install" or leave it for later . Updating is key for security, but we've also seen patches that cause serious errors, blue screens of death, or even problems with SSD drives . Knowing how to distinguish a normal update from a potentially dangerous one is increasingly important.
In recent versions of Windows 10 and Windows 11, real-world issues have arisen: patches that fail to install correctly, installation errors like 0x800f0922, SSDs that become unrecognized after prolonged write operations, and even ransomware disguised as a system update . This article will guide you step-by-step, with concrete examples, through understanding these issues and providing you with the tools to minimize risks and stay protected.
Types of Windows updates and why they matter
The first step in assessing whether an update might be dangerous is to know what type of patch you're dealing with . Windows is primarily updated through two main groups of updates: feature updates and quality updates , each with its own risks and benefits.
Feature updates are the major versions that arrive periodically. They typically appear about once a year in Windows 10 and Windows 11, and include new features, design changes, performance improvements, and security fixes . They are installed almost like a system version upgrade.
These feature updates in Windows 10 are offered automatically to consumer devices and business computers not managed by corporate tools . When your version approaches its "end of service ," Windows Update tends to force the installation of the new version so you continue receiving monthly patches.
Quality Updates , on the other hand, are the typical monthly and cumulative updates. They are released much more frequently and usually include security patches, minor bug fixes, and sometimes a minor feature . Their main purpose is to patch vulnerabilities and refine the system.
In practice, both types of updates arrive via Windows Update . To receive the monthly updates, you need to be on a supported version (for example, the latest version for Windows 10 is 22H2). If you're on a very old or unsupported version , you'll simply stop seeing those critical patches, and that's a dangerous situation... not because of a lack of updates, but because of the absence of them.
How to tell if an official update is problematic
Although Microsoft tests its patches thoroughly, it's not uncommon for a specific update to arrive with bugs that affect a group of computers . This doesn't mean it's "malicious," but it can certainly be problematic. The key is knowing how to interpret it and reacting promptly.
A recent example is the KB5089549 security update for Windows 11. Microsoft acknowledged on its website that, on certain computers, it generated error 0x800f0922 during installation . The process seemed to start well, but around 35-36% of the way through, after restarting, the installation would fail and revert.
In these cases, the main symptom is that Windows attempts to install the patch, restarts, displays an installation percentage, and then a message appears stating that "the changes could not be completed ." Upon returning to the desktop, Windows continues to function, but that specific update remains pending; you can verify this in the update history.
Microsoft explained that the problem with KB5089549 stemmed from insufficient free space on the EFI system partition, particularly on systems with 10 MB or less of free space on that partition. The system would start the installation, but when it needed to write to that critical partition, it would run out of space and revert the change.
In these scenarios, the direct risk to the user isn't that the PC will break down, but rather that it will be left without the security patch . Your Windows will boot normally, the applications will work, but you'll remain exposed to the vulnerabilities that the update was intended to fix. The best course of action is to try to resolve the issue (for example, by freeing up space on the EFI partition or applying the policies that Microsoft suggests) or wait for a patch.
Updates that can damage hardware: the case of SSDs
More worrying than a failed installation is when an update starts interfering with things it shouldn't: the hardware. With the Windows 11 KB5063878 update (version 24H2), there have been reports of SSDs no longer being recognized by the system after certain intensive write operations.
According to user testimonials, the most common pattern is that, after installing KB5063878, some SSDs based on Phison controllers (such as the Corsair Force MP600, Kioxia Exceria Plus G4, or SanDisk Extreme PRO) stop working after long write operations exceeding 50 GB at a time . The drive disappears from Windows as if it had suddenly failed.
The risk increases if the SSD is above 60% usage or if it's a model without DRAM . These drives rely more on system memory for their cache, and in demanding scenarios, they can be more susceptible to firmware or driver errors.
In the specific case of KB5063878, Microsoft has only officially acknowledged one other bug (an installation error 0x80240069, supposedly fixed in mid-August) . They haven't admitted to the SSD issue, which creates considerable uncertainty: users see a clear pattern, but there's no official communication or patch to fix it.
If you've installed this update on a computer with an SSD and are concerned, you have several options. The most prudent, until there's confirmation or a specific patch, is to avoid tasks involving large writes (copying huge files, aggressive performance tests, etc.). Another possibility is to uninstall the update , knowing that in doing so you'll lose the security improvements it included.
In your specific situation, if you installed KB5063878, didn't notice any problems, and uninstalled it quickly, it's very likely you didn't cause any damage to your SSD or the rest of the hardware . If the computer boots normally, the drive is recognized without issues, and no SMART errors appear, the system shouldn't have been affected by simply installing and removing the patch.
How to assess the real risk after uninstalling an update
When people talk about an update "breaking PCs," it's easy to panic. Uninstalling a conflicting patch is a perfectly valid measure and, as a rule, shouldn't leave any lasting effects if the system continues to function correctly.
To assess whether any damage has occurred after installing and removing an update, consider several points. If Windows boots normally, there are no errors when accessing your drives, no recurring blue screens, and applications function as usual, there are no clear signs of damage . SSD failures caused by these types of patches typically appear immediately or shortly after problematic write operations.
You can add an extra layer of peace of mind by performing a couple of checks. Check the health of your SSD using tools that read the disk's SMART data, run an error scan on the drive directly from Windows, and back up your important data . If all of that passes without incident, there's no real reason to think that the brief patch installation has "broken" anything.
What is important to understand is that uninstalling a security update leaves you vulnerable again to the vulnerabilities it was meant to fix . Therefore, it's advisable to keep an eye out for future Windows Updates announced by Microsoft or your SSD manufacturer, and install the next patched version as soon as it becomes available.
End of support for Windows 10: When does it become truly dangerous?
Another key factor in determining whether an update (or its absence) is dangerous relates to the operating system's lifecycle . Windows 10 already has an expiration date: as of October 14, 2025, it will no longer receive mainstream support . This means that, after that date, it will no longer receive security updates for the average home user.
The end of support occurs gradually. First, major feature updates are discontinued, but monthly security patches continue to be released . Later, maintenance is completely abandoned, and there are no more bug fixes or patching of security vulnerabilities, no matter how critical.
When a system enters this state, it becomes a prime target for cybercriminals . It's quite possible that some have discovered serious vulnerabilities and kept them hidden, waiting to exploit them as soon as Microsoft stops patching the system. Windows XP is the classic example: for years, attacks continued to appear targeting flaws that no one was going to fix.
In addition to security concerns, over time new applications and hardware become incompatible with an unsupported version of Windows . Developers stop testing their products on that system, strange errors appear, some programs fail to launch, and new devices (mobile phones, cameras, peripherals) may not be recognized or may function in a very limited way.
Therefore, if you're still using Windows 10, the general recommendation is to plan your upgrade before support reaches its end . Ideally, you should upgrade to Windows 11 or a more recent version while your system is still receiving updates.
Options to stay protected if your PC doesn't support Windows 11
If your computer is somewhat old and doesn't meet the official Windows 11 requirements , such as the well-known TPM 2.0, you're not completely out of luck. There are several possible solutions, each with its own drawbacks.
The first step is to check if you actually don't meet the requirement. Many relatively modern computers do have TPM 2.0, but it's disabled in the BIOS/UEFI . Accessing the firmware settings and enabling the TPM module (or fTPM on AMD motherboards) might be enough for the Windows 11 installation wizard to approve it.
If your hardware still fails the filter, there's an official method to bypass the TPM or CPU check using the Windows Registry . It involves adding a key called AllowUpgradesWithUnsupportedTPMorCPU to HKLM\SYSTEM\Setup\MoSetup with a value of 1. From that point on, the installer will allow you to continue, although it will warn you that the computer is not supported.
There are also third-party tools and scripts that automate this "trick ," such as projects that download modified Windows 11 ISOs or install the standard version but disable certain checks. These methods can work, but they must be used with caution, always from trusted sources, and with the understanding that they are not officially supported by Microsoft.
For those who don't want to complicate things or have a PC that's already struggling, another option is to stick with Windows 10 and rely on extended support . For example, for a while you can receive some additional patches through mechanisms like Windows Backup or enterprise extended support programs. These are partial, temporary solutions not designed for home users, but they can give you a few extra months.
Fake updates: when the danger isn't Microsoft, but ransomware
So far we've talked about official updates that go wrong. But there's an even trickier scenario: fake updates that are actually disguised malware, like the Big Head ransomware . This isn't a bug; it's a deliberate attack.
Big Head is a clear example of how cybercriminals manage to deceive users. It presents itself as a very convincing window simulating a Windows update, even using a forged Microsoft digital signature, making it appear completely legitimate . The victim believes they are improving their security when in reality they are installing a file encryptor.
Once the user accepts the supposed update, the ransomware runs in the background and begins encrypting documents, photos, databases, and other important files . When finished, it displays a ransom note demanding payment in exchange for the decryption key, leaving the PC virtually unusable.
This type of threat takes advantage of the fact that many users are already accustomed to seeing update messages and don't question their origin . The usual trick is to distribute the malicious installer via email, compromised websites, deceptive ads, or pirated downloads, always trying to give the appearance of legitimacy.
The best defense here is twofold. First, configure Windows updates to install only through the system itself (Windows Update) or a trusted IT provider , never downloading manual patches from dubious links. Second, maintain good backups so that, if an infection does occur, you can restore your files without incurring any costs.
Best practices for minimizing risks with updates
Ultimately, the key is not to live in fear of updating, but to apply a few good practices to minimize the risks of both faulty patches and fake updates.
The most important thing is to keep Windows, browsers, and other key software up to date, but only through official channels . Enable Windows Update, allow automatic updates, or schedule them for busy times so restarts don't disrupt your work, and be wary of any "update" that appears outside of official channels.
Another essential pillar is regular data backups . Use an external hard drive, a NAS, or a cloud service, and make sure there's at least one copy stored offline so ransomware can't encrypt it as well. A good backup policy turns many potential disasters into mere inconveniences.
Don't forget to strengthen perimeter security: reliable antivirus software, an active firewall, email filters that block phishing and suspicious attachments, and basic training for all users who access the computers . Most successful attacks begin with a click on the wrong site.
Finally, it's a good idea to monitor system behavior after major updates . If you notice unexpected slowdowns, disappearing disks, boot errors, or repeated blue screens immediately after a specific patch, investigate: review the update history, see if Microsoft has acknowledged the problem, and consider uninstalling the patch in question or repairing the installation.
Taking all these precautions, updating ceases to be a game of Russian roulette and becomes what it should be: a maintenance routine that strengthens security instead of jeopardizing it . Understanding what types of updates are available, how they behave when something goes wrong, what the end of support for Windows 10 entails, and how to identify malicious fake "updates" allows you to calmly decide when to install, when to wait, and when to decline, keeping your PC protected without sacrificing stability.
