we come bit off-topic with that 
I thought the MS-Defender-Bug is already fixed. Not ? This might be important for some users.
In generaly, and already in other threads done, I recommend allways to put this big applications folder at the exceptions for runtime-checking.
About sound issues… yes… there are also aready threads related to sound-issue and I remember for another user in forum which uses only a external usb-dac and where I also recommened to disable in this case the onboard sound-card in BIOS. But of course… if you use the onboard sound, the drivers must be up2date. There are lots of issues with sound-drivers and windows.
( and I not use the nvidias sound drivers… I not include it while installation ) ( edit: exlude->include )
