Windows 11 updates come and go with a few problems with the latest optional update, so watch out.

In a few weeks, Microsoft should offer the next major update of its operating system, the 22H2. In the meantime, the editor continues of course to deploy what it calls cumulative updates for the current version, the 21H2. The problem is that this does not always happen exactly as the developers had planned. Thus, online since August 25, the optional update stamped KB5016691 seems to contain a bug that is disabling to say the least.

Fortunately, the thing does not cause anything dangerous and even if you are affected, you do not risk data loss or system crashes. What's more, the problem doesn't seem to affect users who use a local account. In fact, as Microsoft itself has confirmed, the bug is related to the first startup on a newly created account by the user. In this case, it is possible that the login screen simply does not work for a few minutes. There is no specific time limit, but after these few minutes, the problem should resolve itself and never appear again for the said account.

As we said, as Windows Latest explains, this bug doesn't seem to affect local accounts, nor does it affect accounts associated with an Active Directory or Azure Active Directory domain as is often the case in enterprises.

Finally, Microsoft specifies that an " emergency solution " is already in place. It works through the " known problem restoration system ", a Windows feature specifically designed to solve these problems of faulty patches. Microsoft also explains in detail the procedure to follow in case of problems with this optional update: everything is specified on this page of the editor's technical support.
