Microsoft released the Windows 11 autumn update at the beginning of October. However, a bug has crept in. The installation creates an almost nine gigabyte cache file that cannot be deleted.
You could fit an entire modern OS in that space, together with all the drivers, a web browser, an office suite, graphics editor, an IDE and a compatibility layer for running Windows applications.
Yup, my Linux install is a bit over 10GB, which honestly surprises me and means I probably should clean stuff up, because usually my Linux base install is around 8GB. After a quick look, I have several old versions of compilers and runtimes that can be cleaned up w/o breaking anything.
I can't imagine thinking that an 8GB cache is fine, and that's nothing compared to the size of the rest of the OS...
