Impacted version is current plus several previous: 4.21.173 and below
Handle leak is pretty obvious:
Over time, a day or two, it’ll climb into the several hundred thousands.
Process Explorer shows the handles are to drive resources (including Xbox/Store games that install xhd)
Disabling the storage widget and restarting the service shows handles stay static with iCUE
The handle count grew on my machine about 18-20/second
HTH, unknown when they will fix, I reported this in iCUE feedback 2 years ago.
