IE Cache Location and Metro App Crash

For very long time I have been creating RAM disk and pointing temp and cache dirs there to improve I/O performance and reduce unnecessary SSD writes. Since Windows 8, changing the cache location of IE (a.k.a. “Temporary Internet Files”) to a RAM disk could result in crashes of Metro (a.k.a. “Modern”) apps, which I didn’t figure out why until recently. The problem is also observable in Windows 10.
