On May 9, a new cumulative update for Windows 11 was released with the code KB5026372. It was supposed to improve the performance of the system.
But the update led to problems, reports Windows Latest. Users complain about VPN connections such as L2TP/IPsec VPN. There was also a noticeable decrease in the speed of downloading and uploading data.
There have been complaints about difficulties downloading files via L2TP/IPsec VPN from sftp. DNS flushing, reinstalling the WAN, disabling the firewall, and IPv6 don’t fix the problem. The update also enabled BitLocker Drive Encryption. This has led to some computers falling into what is known as an “endless” automatic recovery loop.
Only reinstalling Windows and a complete system cleanup helped fix this problem. For some users, after installing updates, the computer shuts down instead of restarting. Microsoft has not yet acknowledged the existence of problems.
Users are advised to roll back to the old version. Earlier, the company acknowledged the problem with drivers in Windows 11.
