Microsoft has had a rough go of its Windows updates, with the company pulling one of its latest ones and warning users about it.

Windows 10 update KB4524244 was pulled by Microsoft after four days following reports it was causing crashes and freezes on every available version of Windows 10. On a support page, the company made the following statement:

“To help a sub-set of affected devices, this standalone security update has been removed and will not re-offered from Windows Update, Windows Server Update Services (WSUS) or Microsoft Update Catalog.”

Although Microsoft has pulled KB4524244, Windows Latest is reporting that update KB4532693 may be just as bad, or worse.

“For some folks, the update is reportedly deleting files, while others report that Microsoft has moved all their desktop data to a temporary folder,” writes Windows Latest.

“Microsoft’s latest update has now run into more trouble, as users are reporting serious issues after applying Build 18363.657 or 18362.657. The update, which had previously been deleting files and failing to install for some users, is now causing boot failures.”

Microsoft has had a troubled history with Windows 10 updates, and these latest missteps only reinforce that perception. What’s worse, these issues are impacting security updates, increasing the likelihood users will avoid critical updates altogether, leaving them vulnerable.
