Microsoft's Patch Tuesday can't break stuff if it won't install
KB5132061 throws 0x800F0993 and 0x800F0989 errors, and Redmond is saying nothing
Microsoft's latest Patch Tuesday update, KB5132061, is reportedly causing issues for some users attempting to install it. The update, which contains security patches and fixes for various Windows products, has failed to install for a number of users, with error codes 0x800F0993 and 0x800F0989 appearing. Microsoft has not yet issued a statement or explanation for the problem.
Users have speculated that the issue may be related to Windows Sandbox, but reports indicate that problems persist regardless of its status. Alternative solutions such as using DISM or downloading the update manually have been suggested. The update addresses 726 vulnerabilities in Windows alone, making it essential for users to install.
However, the difficulties faced by some users are frustrating. Microsoft has recently encountered more issues with its patches, with out-of-band releases becoming more common following updates that broke functionality. For example, an out-of-band release was pushed out in September 2026 due to trouble with Remote Desktop Services caused by a previous update.
The October Patch Tuesday for Windows Server caused issues with Exchange Servers, leading to a registry edit workaround. No out-of-band update was required, as the problem was reportedly resolved in the November update. At least this latest release appears to have issues before users can even experience any broken functionality. The Register has reached out to Microsoft for comment.
