If you find your PCs running low in storage memory lately, then this is most likely because Microsoft is automatically downloading between 3.5 and 6GB Windows 10. This allegation, as The Inquirer reports, is confirmed by Microsoft stating that they are indeed downloading Windows 10 without users' permission.
This allegation followed after an Inquirer reader reported that he discovered a ~BT folder without going for a free upgrade.
"The symptoms are repeated failed 'Upgrade to Windows 10' in the WU update history and a huge 3.5GB to 6GB hidden folder labelled '$Windows.~BT'. I thought Microsoft [said] this 'upgrade' was optional. If so, why is it being pushed out to so many computers where it wasn't reserved and why does it try to install over and over again? ...My own internet (slow DSL) was crawling for a week or so until I discovered this problem... Not only does it download, it tries to install every time the computer is booted," said the anonymous reader.
Other Microsoft users voice out the same sentiments as early as July. Deleting these files, however, is not a one-click solution away, thus Addictive Tips' 'What is the $WINDOWS.~BT Folder on my hard drive?' the article shared the key to this headache. Tip advice users to uninstall the KB3035583 update before removing the actual folder.
Microsoft, in response to The Inquirer's questions, said that "For individuals who have chosen to receive automatic updates through Windows Update, we help upgradable devices get ready for Windows 10 by downloading the files they'll need if they decide to upgrade. When the upgrade is ready, the customer will be prompted to install Windows 10 on the device."
This does not surprise some people as Microsoft has been aggressively marketing its latest Windows 10. They have also revealed that they are already running on an estimated 50 million gadgets. Installation of Windows 10 is now aiming a new breakthrough of 75 million devices and will edge towards 1 billion.
