Microsoft promises it is close to resolving an issue with an update that refuses to install on some PCs.
Microsoft is in the final stages of fixing a Windows 10 update that endlessly rebooted some PCs.
Microsoft has acknowledged the problem affecting the patch for the Windows 10 Anniversary Update and said it is on the verge of correcting it.
"We've been working diligently on this issue and are finalizing a clean-up script that will fix the underlying issue preventing the install of KB3194496 (Cumulative Update 14393.222) for affected users," said a Microsoft employee on the firm's official forums.
"Your patience during our research and subsequent work is greatly appreciated."
Microsoft has been criticised for releasing this latest update to the general public after the installation problem was spotted by people testing early builds of the OS under the Windows Insider program.
The issue is the latest in a series of problems caused by Windows 10's frequent updates. Most notably, the major Anniversary Update to the Windows 10 in August, which caused some users desktops to freeze up, made Cortana to vanish from the Taskbar, and disabled widely used webcams.
The tech giant began pushing out the Windows 10 Anniversary Update in August but has said the staggered rollout will not be complete until November.
At the recent Ignite conference in Atlanta, Microsoft announced the OS is being used on some 400 million devices, marking a slowdown in uptake since Microsoft ended the free upgrade offer for Windows 7 and 8 users.
Microsoft is trying to make it easier for businesses to upgrade to its latest OS, releasing a free service that will scan a firm's IT estate for incompatible software and hardware, and suggest fixes.
