Microsoft rolled out some of the best operating systems in the world, but even those came with inherent bugs that caused systems to run slower than expected or even to freeze altogether.

The recently released Windows 10 Anniversay Update that came out at the beginning of August hit users' systems hard, leaving their webcams disabled and causing them more than a few login freeze issues.

Microsoft assured its customers that it was preparing an update to take care of the bugs, and it kept to its word on the last day of August.

Keep in mind that the upgrade to Windows 10 Anniversary Update came out on Aug. 2, with a slew of novel features and enhancements targeting both everyday users and enterprise clients. Features such as a less power-hungry Edge browser, Windows Ink, Cortana improvements, polished gaming experiences, security upgrades and more were delivered in the update.

Microsoft's digital assistant Cortana and the digital stylus that was packed with the Surface Pro tablet were supposed to get new features and improved functionality in the Anniversary Update.

However, the update did bring two unexpected gifts. One was a strange capacity to randomly disable webcams, while the other was a strange propensity to freeze systems where users had their app data on one logical drive and their OS on another.

CBC News asked Microsoft about the issue and the company explained that it is aware of the problem and is taking steps toward fixing it.

The Windows developer noted that a number of apps that made use of compressed MJPG and H.264 streams for webcams were incompatible with the Windows 10 Anniversary Update.

"We are currently rolling out a fix that should go public shortly," Microsoft said.

Reports are indicating that despite the fact that the update does not target every bug that users reported in the Windows 10 update, it takes care of the critical problem of freezing during login. Windows 10 users can head to Microsoft's site to update to the latest version.

Additional insights from Engadget are showing that Microsoft fixed the login freeze issue, but a consistent number of users are still left with their webcams disabled.

Microsoft offers a detailed walkthrough on its tech support forum to those who still stumble upon login problems.

Prior to the fix, the best strategy for users was to revert to a previous installment of Windows 10.

The Anniversary Update generated other hardware issues as well: Amazon Kindle users complained that their PCs crashed as soon as they plugged in their e-readers via USB.
