Windows 7 running slow (suddenly)

[Timo_Toivonen]

Hello,

I have Windows 7 on Parallels Desktop for Mac (Build 9.0.24251) and since today it's so slow it's unusable. I have not edited any settings in Parallels, neither have I installed any new software on Windows. Yesterday, Windows was running very smoothly, no problems whatsoever. My Mac side (OS X 10.10) is smooth, no lag there.

Anyone else experiencing this slow-down at the moment with Windows 7?

Thanks, Pom

I'm having the same issue, I tried making a new VM and that didn't work, uninstalling and reinstalling didn't work either.

I don't know what happened but today Windows 7 with Parallels on Mac is back to normal response and speed. I didn't change any settings. I checked the tracing specs and no driver was even close to 10.000 interrupts per second.

If it helps, my setup is Win 7 on a Mid2011 iMac, with a bootcamp and with Parallels (at the same time).
