Some users who have installed Windows 10 Anniversary Update on SSDs are experiencing problems with their computers freezing.
Microsoft does not yet have a fix available, but it is aware of the issues and is working to get a patch pushed out to those who have been affected. While there is not a proper fix available at the moment, the company has provided details of a couple of workarounds that should do the job for the time being.
Writing on Windows Answers, a Microsoft administrator said: "Microsoft has received a small number of reports of Windows 10 freezing after installing the Anniversary Update on systems with the operating system stored on a solid-state drive (SSD) and apps and data stored on a separate drive. This issue does not occur when starting Windows 10 in Safe Mode. If you are experiencing this issue, we will be providing updates to this thread."
