How do I replace a W7 driver...

[apollo911]

I did a clean install of Windows 7 RC on a Dell 1545 which had been running Vista Basic.

All was well except that the DVD writer vanished from explorer and Device Manager at random intervals.

I re-installed the Vista Basic and the drive worked perfectly. I backed up the driver so I have a cdrom.inf and cdrom.sys from the working Vista system

I then upgraded the Vista system to Windows 7 and sure enough the DVD drive problems came back.

I cannot find a way of replacing the Windows 7 driver with mt nice working Vista driver.

I can't update it as W7 says the current one is the best, I can't delete the driver because apparently I need TrustedInstaller permissions, I can't give myself permissions as W7 doesn't give me the option under the security tab on the driver folder.

Help please!!

Device Manager > Right Click Device > Properites > Driver Tab > Click Update Driver > Choose "Let me Pick a From a List..."> Select Have Disk > Choose the driver you want to use.

You need to be able to Take Ownership of the object to be able to delete it in the systems folder as its a protected file...
Add this to your rightclick context menu...
Just download the registry file made by Brink (Forum admin for Seven & Vista Forums) double click it, then reboot & that option will then be there for you to use when you need it.
It was made for Vista but works in W7 too.

Be aware also that sometimes driver infs come with other files as well like my tuner card did, although I should think for a standard dvd drive it should be ok.
