Windows 10 Latest Cumulative Security Update Can Delete Personal Data Including Restore Points And Programs

A small but rapidly rising number of Windows 10 users are experiencing some highly concerning events after installing the latest Cumulative Security Update. After installing the latest security update, some users have reported partial or complete data loss, including the deletion of desktop files, programs, and program data. What’s even more concerning is that the update is reportedly wiping out some Windows OS Restore Points, which usually serve as a critical backup or reversing option under such circumstances.

The Windows 10 KB4532693 security update appears to be causing some serious trouble to a few Windows 10 OS users. The update is reportedly causing loss of some user data such as the desktop files. It is important to note that the reported cases are quite small in number. However, considering the potential severity of the issues that the Windows 10 KB4532693 is causing, it is important for Microsoft to issue a fix soon.

Windows 10 KB4532693 Reverts Certain System Settings To Their Defaults And Also Removes Files:

The Windows 10 KB4532693 Security Update arrived on Windows 10 OS recently and has immediately been the cause of concern for many. Previous reports have indicated that Windows 10 KB4532693 security update reverts certain system settings to their default settings and also removes files from the desktop. Incidentally, the update appears to rename the main user profile folder and files.

The restoration of the files and folders was rather easy for some by going to the C:\Users profile folder ending in .000 or .bak name. Simply put, it was previously believed that the security update merely renamed some important files and folders. However, new reports indicate some users have permanently lost some of their data. In other words, while many users are able to restore their files from the temporary folder, some users who have lost their data, are unable to get it back through the temporary profile folder.

An increasingly populated thread on Microsoft’s answer forum appears to indicate the high severity of the issues caused by Windows 10 KB4532693 Security Update. What’s even more concerning is that the data deletion appears to be permanent. In other words, uninstalling the security update does not bring back the missing data.

Some of the main areas which appear to be affected by the Windows 10 KB4532693 Security Update include the primary Desktop, where the icons, as well as the wallpaper, are deleted, Taskbar and Start Menu appear to be reset to their basic or initial setting. Although the number is small, some of the affected users claim there’s no user data and no temporary account. There are no restore points as well to reverse the actions.

“Thank you, Microsoft for the latest updates which totally wiped all settings from my system on each startup. Everything reverted to basic settings [and] all my program information and settings were also deleted from every program on my system. Several apps were deleted completely, keyboard settings, language screen res everything gone. Updates now turned off,” wrote one Windows 10 OS user.

Microsoft Yet To Officially Acknowledge The Devastating Effects Of Windows 10 KB4532693 Security Update:

Microsoft hasn’t acknowledged the problems that the Windows 10 KB4532693 Security Update reportedly caused for some Windows 10 OS users. A few users have claimed that they have established contact with the company’s Customer Support, but are yet to hear back.

Based on the reports, it is feared that the data that the security update deletes, might not be recoverable. In other words, it is highly unlikely that the update might have merely hidden or obscured the data or broken some linkages that connect the user to the data.
