Windows 8.1 stutters, resolution does not fix itself

Damn, I have another problem that there wasn't before the update. When I resize the virtual machine window i can hear a noise inside my Mac (like a "clack"). This happens every time I resize the window. I'm worried about
It because it's a strange mechanical noise never heard before. Anybody with the same problem?

 

I can't get past Windows 8.1 loading personal settings after entering password.

 

same problem.

Problem ID: 30675968

i suspect manual drive install is required for every1 who update.

please automating the process into new parallels updates.

 

same here
after uninstall para tools, can not start win8.1
after the vm restarted itself 3 times, entered self auto repair mode and restarted.

 

----------------------------------------------------------------------------------------
If para tools is uninstalled. the Win8.1 will not start. and yes, with Blue Screen.
it will keep restarting Non-Stop, saying in the state of auto-repairing.

------------------
or you can press Cmd+R, typing in "devmgmt.msc",

open drop-down in the display.

right-click Microsoft basic driver, select auto update.

it will update into parallels driver by itself.
