The youngest version της Microsoft των Windows 10, τα Windows 10 της έκδοσης 20H2, φαίνεται ότι περιέχουν ένα σφάλμα που μπορεί να καταστρέψει το σύστημα αρχείων του διαμερίσματος των Windows και να προκαλέσει μπλε οθόνες κατά την επανεκmovement.
Reports indicate that running the chkdsk command may cause file system corruption resulting in blue screen of death (BSoD) on the first system reboot after the disk check operation is complete.
Günter Born reported the problem with more details on his blog.
Reports that an administrator discovered (German forum link) the problem after upgrading the systems to Windows 10 version 20H2 and running the chkdsk c: / f command after installing the update.
The command checks drive c: for errors and fixes them immediately, if any.
The devices encountered an error in the NTFS File System during the reboot. Analysis of an active device, which had been scanned, showed that the partition where Windows was installed appeared as a RAW partition, suggesting that repairing the chkdsk command corrupted the NTFS file system.
Further analysis provided the following information:
- Systems running Windows 10 20H2 appear to be affected.
- The issue seems to affect Solid State Drives but one user reported that a VM system on a regular hard drive was also affected.
- Cumulative update KB4592438, released in Patch Tuesday of December 8, 2020 seems to be the cause of the issue.
It is not clear if all Windows 10 20H2 devices are affected or if the problem is only with devices with certain features. It has been confirmed that no new installation of Windows 10 in version 20H2 is affected.
So administrators should back up their Windows partition before running the Check Disk command on Windows 10 20H2 devices that have December 2020 updates installed.
Microsoft has not yet confirmed the problem.
