System users Windows 11 facing a sudden loss of free disk space is not their own fault. The latest reports reveal a serious system bug that can take over completely unnoticed even up to 500 gigabytes of storage space. In this way, the performance of the computer and the speed of the entire system are impaired.
A hidden culprit in the application permissions file
The problem is directly related to the service that regulates the permissions of applications to access hardware components such as the camera, microphone or location. Inside the official notes on the latest system update under the tag KB5095093Microsoft has quietly confirmed space optimization for this database’s specific log file.
This file normally takes up only a few megabytes, but due to a code error, it starts to grow uncontrollably. It swallows tens, even hundreds of gigabytes and in some cases completely blocks the disk.
How to check the presence of a system error
A classic check of the list of installed applications through the system memory settings will not reveal this problem, because the operating system does not transparently show which hidden folder is causing the increased consumption.
In order to locate the problem, it is recommended to use specialized external tools for analyzing the structure and usage of disks that can accurately scan hidden system paths.
Alternatively, you can check by running a command line with administrator rights, entering the official command for temporary folder mapping, which will immediately reveal the actual size of the disputed database on your computer.

Official solution and recommended steps
This problem has been present in the system for some time, and the first user reports on the forums appeared a year ago. Microsoft indirectly acknowledged the bug through an optional update from June this year, while an official automatic fix will be delivered to all users as part of the regular July security patch package.
This update can be installed immediately through the options in the system update section, where you should look for the mentioned package KB5095093.
Users are strongly advised not to try to delete this file on their own or to forcibly shut down accompanying system services, because unauthorized changes to system files can cause chain errors and instability of the entire operating system. PCWorld concludes.
