All is good againAround one out of 10 Windows 10 users ran into trouble when trying to install a update intended to fix a problem that was causing Explorer.exe to frequently crash following an upgrade to Windows 10 Build 9879. The problem was further exacerbated by the fact that Microsoft said it didn't have a new build planned until early 2015. If you're one of the people who ran into trouble, here's a heads up that Microsoft has released a hotfix to address the issue.
According to Microsoft, the problem affected about 12 percent of PCs when installing the update. In those instances, the update would fail to install, and after doing some digging, Microsoft determined there were two underlying bugs that needed squashed.
The first is that in Build 9879, Microsoft introduced some new System Compression code that systems with SSDs can take advantage of to reduce disk usage by the OS. However, the logic for low-space detection would get inverted in some instances, and Windows compresses automatically as a background operation.
A second bug appeared on PCs that had system compression enabled. It would muck with how the file system tracks deletes, causing the installer to think the temp files failed to extract correctly.
There was a workaround for the problem, though now the easiest solution is to apply the new hotfix that's now available through Windows Update, according to Microsoft's Gabriel Aul.
