Microsoft's much anticipated update of Threshold 2 for Windows 10 is plagued by numerous bugs and errors several users have encountered while installing Windows 10's first major update.

A number of users have flocked to the Microsoft support forums reporting their installation freezes at certain points. Microsoft has already acknowledged the problem, saying that some Threshold 2 installations freeze at 44 percent because of the presence of an SD card.

"If your install is freezing at 44 percent, check if you have an SD card inserted and remove it, and the update should be able to progress beyond this spot," says Anannya Podder, Microsoft support engineer. "If you needed the SD card for additional disk space, see if you have a USB/Mini-USB port available that you can use instead for the upgrade."

Unfortunately, the issue does not address all problems. Podder says users who need their SD card for storage will have to free up disk space. No official word has been made about how much space Threshold 2 takes up, but the update will certainly take up a considerable amount of space.

Moreover, not a lot of users seem to find Microsoft's response very helpful. For one thing, many users see their installations freezing at several other points aside from 44 percent. One user says his installation is stuck at 34 percent, another at 91 percent and perhaps the unluckiest of them all at 0 percent.

Other users say the freezing forces them to restart their PCs, only to find out that their Windows has reverted back to Windows 7. Yet, others say Windows persistently tells them that Threshold 2 has been successfully installed, but their PCs are still running on an earlier build.





"While it looked like the November update (KB3106246) was installing and reported as 'successfully installed,' it wasn't," says one user. "Tried it again and it now reports that the system is up to date. System information still tells me: 10.0.1240 Build 10240."

Microsoft has yet to respond to the additional problems, and there is unfortunately no available fix to date. The only thing advised for users is to remove some of the unneeded junk from their storage and reinstall Threshold 2 again with crossed fingers.

As the first major update to Windows 10 since its July 29 release, Threshold 2 brings significant improvements. These include performance enhancements that Microsoft's Gabe Aul says increase boot time by 30 percent compared to Windows 7, a smarter Cortana, and beefed up Microsoft Edge
