Windows 8.1 stutters, resolution does not fix itself

[Joibisi]

Hi!

Today I installed Windows 8.1.
I had Windows 8 installed as a virtual machine on my parallels 8 for a couple of months now and everything worked perfectly. After the upgrade today, windows suddenly stutters at the most basic tasks like opening the desktop or switching back to the tile menu.
Another strange thing is, the resolution of Windows does not optimize itself anymore like it did before the update. When I resize the window in which Windows is displayed it just gets scaled. When switching to fullscreen its just an upscaled version. I can however change the resolution in the system preferences of windows itself where the display is called "parallels vu".

Can somebody help me fix my problem? I need Windows to work but I do not have a portable Windows machine which was the reason I bought Parallels in the first place

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?

patavinus,

How exactly Windows fails to start without tools? Does it show blue screen?
After all it's possible to update display driver manually. The downside is that if some other components of Parallels Tools are also misconfigured, you'll still need to reinstall.
To update display driver right-click on Microsoft Basic display and select Update Driver Software... from the menu. Then press "Browse my computer for driver software", then "Let me pick from a list of device drivers on my computer", then "Have disk..." button. Click "Browse..." button and navigate to C:\Program Files <or Program Files (x86) for 64-bit Windows>\Parallels\Parallels Tools\Drivers\prl_dd, then double click prl_dd.inf file and click OK. Then click Next and confirm driver installation.

----------------------------------------------------------------------------------------
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.
