windows virtual pc slow performance

It was a bit slow for me as well when I first installed. After running CCleaner and disabling unnecessary services, it is a little better. Still I hope Microsoft will improve upon this in future updates.

Well, I have found 2 location for sony vaio vgn-z31xn/b drivers for windows 7 as well as utilities... Better you check everything in these locations;

1. VAIO Country Selection Page check out windows 7 drivers and utilities, but you may not find all of the drivers and utilities there. Espacially hardware drivers (parser service, i/o drivers, chipset etc. and not all of the utilities) are missing so, I highly recommend the us support site, but be careful about vaio model. iti is different there so check out drivers and utilities for vgn-z670n/b which is exactly identical notebook.
2. Sony eSupport - VGN-Z670N/B - Software Updates & Drivers
choose your operating system and 32 or 64 bit.... all of them are here...

after a clean install with windows 7 drivers, install the utilities and averything should work perfectly.

Dear folks,

let me summarize my experiences on a DELL Latitude E6400:

1. While nothing runs in the virtual XP, the processor usage (reported by the VPC's task manager) is pretty high, over an average of 50%, and even window resizing is extremely slow.

2. If I start something in the real Windows7 machine, e.g. a Media player playing some music, the processor usage in the real machine inreases of course, while the proc usage in the virtual XP falls back to around 1% at the same time, and the virtual machine runs just perfectly, not slow at all.

3. I have checked "Advanced power settings" within "Power options", where in "Processor power management" both "Minimum processor state" and "Maximum processor state" are set to 100% when plugged in AC.

4. Tried the same thing on a slower machine (DELL Latitude D630 with a 1.8 GHz Core2Duo). In that case the processor usage in the real machine was higher, about 4-5 % even when idling, and the speed of the VM was just OK.

5. I suspect however there may be some problem in balancing the CPU power between tasks, but this is something I do not have the slightest idea about. Although it is ugly, but currently if I need VM, I start the Media player in W7 first and go ahead.

I tried both 32 and 64 bit W7, all service packs in the virtual XP, even XP mode, the behaviour was the same.

Could you who have the same problem try the same thing in your environment?

Many thanks

Hi Kari,

Thanks indeed for the quick help, integration features were enabled.
I edited the Options.xml file as you described, and it did change behaviour, it's perfect now! It is just unbelievable after a few days of continuous reinstalling and trying different ideas.

Thanks, thanks, thanks!
