Windows 7 Virtual Device Drivers


Likes # 0

Hi Guys

I'll try and make this as brief as possible, although it's complicated...

About a year ago, when I first got my Win 7 PC I installed an old programme...'Microsoft Picture It! 2.0' (PicIt!) . However, it didn't run successfully even in 'Compatibility Mode'. So I decided to install a virtual drive, using VMware and WinXP. Although the virtual install was a success, when I installed 'PicIt!' it was no better. So I removed PicIt! and the virtual drive. But then my Win7 started playing up. So I did an 'In Place Repair', which was, in the main, fine. I noted that there were still instances of VMware in the Registry. I've run CCleaner Reg Clean many time, but it doesn't remove them. Then, last week I noticed when I looked in 'My Computer' it shows a drive called 'System Reserved E:' 99.9 MB which was mainly empty. Where all the other drives shown, both external and internal, space used is depicted as a blue line, drive E: is shown in red? I'm thinking that it may be the space I allocated for the virtual drive?

But when a few days ago I decided to give PicIt! another try in Win7, after I installed it I noticed that drive E: is now showing as...8.55 MB free of 99.9 MB. As for PicIt!, now in compatibility mode WinXP it's performing fine. But when I try to install 'Rave eJay' or any software from the eJay stable, I get the following pop-up message...

16 bit Windows Subsystem

SYSTEM\CurrentControlSet\Control\VirtualDeviceDrivers. Virtual Device Driver format in the registry is invalid. Choose 'Close' to terminate the application.

When I follow this direction in the registry I can't find any VDD's at all? So, my question is...

Where would the 16 bit Windows Subystem be located and if I find and remove the VDD's, will the Virtual Drive E: (if that's what it is) still run PicIt!?

That red line you describe shown in My Computer means that there is less than 10% space available (or whatever your low disk space setting is set to.)

Have a look in Disc Management to see if that is actually your system drive, if so it will contain the boot files and mbr. Windows 7 creates this on install unless told otherwise. Unless you have set Windows to unhide system files then they would be hidden and explain why you not seeing them.

Sorry but can't answer your main question as its not something I have ever needed to look for.
