The month of January 2026, a second emergency patch for Windows has begun to be issued. This comes after many users were troubled by the ongoing update to . The update will be designed to resolve cloud-related file problems that were first reported this month, according to the update. Nevertheless, some new bugs have appeared with . Questions are raised about the tech giant’s update stability and testing process of this software mess-up, which is a question that has been asked in its recent release.

The second emergency patch of the month is beingrolled out by Microsoft, as it has previously said, to resolve a bug related to its January security release that was linked to an emergency update. Last update was reportedly the first major bug that blocked Outlook and other apps from opening/saving files on cloud services like OneDrive and Dropbox. In some cases, when important data files were saved online, Outlook did not open completely. It was a frustration for many users worldwide, especially those who use cloud file management to do their daily work.

A number of users have reported that it has been fixed by updating the system to the new patch, which is a problem with many users. Microsoft notes that results may differ depending on system setup, but are varying in some ways.

More bugs add pressure on software quality control

Many PCs are apparently not booting into the system after installing the January update, which is said to be a small number of PC. A black screen and an error related to a unmountable boot volume are displayed in these devices, as well as the device’s “unmountability” bootvolume. No fix has been provided yet, so affected users are forced to use Windows‘ recovery tools.

Similarly, Microsoft responds to the issue by saying that they’re investigating the problem and think it affects only a few devices. This is not the first time a security update has troubled Windows users. Reliableness is likely to be improved by updates, not introducing new risks. Despite this repeated behaviour, Microsoft’s software team has been asked by the user to question whether it is reliable or quality control.
