Try downloading the official Windows 8.1.1 RTM update from Microsoft

After a leaked version of Windows 8.1 Update 1 not long ago, it was discovered that there was another way to download this update. According to network shares, people call this Windows 8.1.1 compact and easy to distinguish, and longer-lasting support from Update 1 is quite redundant.

This update is said to be the official version (RTM), but is divided into 6 small packages by various code names, for example KB2919442 and has 32 bit, 64 bit, and ARM versions for device running this operating system. (ARM is the link for Windows RT machines).

You download each patch below, install and then restart the computer after installation error (5 times to reboot). Note that this is only a leak, and some Windows RT users report that their device has a WiFi driver error when updating, so if you intend to install it, you should be careful. It is known that Microsoft will release this Windows 8.1.1 update on March 11 here.
