What’s causing the Microsoft Store Error 0xc000027b and How to Fix it?
Method 1: Setting the Correct Time & Date
In a lot of documented cases, the 0xc000027b error code is a direct consequence of the fact that the date, time, or timezone has been altered during the process of upgrading the machine’s OS. Several affected users have confirmed that for them, the issue was occurring due to the fact that their machine clock was incorrect. This might seem insignificant, but chances are certain Store requests will fail due to a bad timestamp and the Store’s server will not allow the connection to be established. If this scenario is applicable, setting the time, date and timezone correctly should allow you to take care of the issue very easily. Here’s a quick guide on setting the correct time & date in order to resolve the 0xc000027b: If you’re still encountering the 0xc000027b error, move down to the next method below.
Method 2: Refreshing the Store app via Powershell command
As it turns out, this particular issue can also occur due to one or more temp files that are actually producing errors during the validation phase that ultimately forces the Microsoft Store to auto-close. Several affected users that encountered this issue have managed to get the issue resolved by opening an elevated Powershell prompt and running a command capable of clearing all files that are associated with the Microsoft Store component. Here’s a quick guide on doing this: If the same 0xc000027b error code is still occurring, move down to the next potential fix below.
Method 3: Resetting Windows Store
As it turns out, one of the most common culprits that will ultimately spawn this error is some type of corrupted inside the Windows Store component. This scenario is fairly common in those situations where Windows Defender or a different 3rd party security scanner ends up quarantining some items that are essential to the Windows Store. If this happens, the Windows Store will end up closing whenever the utility calls upon the file that has been quarantined. Some users that were also encountering this issue have reported that they finally managed to resolve the issue after they reset the Microsoft Store along with any associated dependencies. This procedure will end up replacing any quarantined instances with healthy copies that will take its place. Keep in mind that when it comes to doing this, there are two ways forward. Options number one involves using the Windows Store reset utility while the second one is more suitable for non-technical individuals that would prefer to do the entire process from the menus of Windows 10. Follow whichever guide you feel more comfortable with:
Reset Windows Store via Settings Menu
Reset Windows Store via CMD window
If you’re still noticing that the Windows Store app crashes and the Event Viewer log points towards the 0xc000027b error code, move down to the next method below.
Method 4: Deleting Windows Store Cache Registry keys
As it turns out, this particular issue can also be caused due to several registry keys that might end up holding temporary data which ends affecting the stability of the Microsoft Store. If this scenario is applicable, resetting the cache conventionally will not resolve the issue since the same registry keys will still remain firmly in place. To resolve this issue in this case, you will need to use Registry Editor to locate the problematic key and delete it swiftly. Several affected users that were also struggling with this issue have confirmed that this operation finally allowed them to fix the 0xc000027b error. Here’s a quick guide on how to get this done on Windows 10: If the 0xc000027b error is still occurring at the next computer startup, move down to the next method below.
Method 5: Performing a repair install
If none of the methods above have allowed you to resolve the issue, it’s probably due to the fact that you’re dealing with a system file corruption that cannot be resolved conventionally. In situations such as this one, the only viable fix that will not produce any noticeable data loss is to perform a repair install procedure (in-place repair). This operation is a little tedious, but it will allow you to refresh every relevant Windows component without losing any personal data, applications, games and user preferences. But keep in mind that performing a repair install (in-place repair) will require you to have an installation media.
