How can I replace my driver files?

My old desktop computer hasn't had a driver update in years and cannot recognize my mouse or USB wireless adapter. My keyboard which I used on it long ago still works. I'm trying to transfer drivers from my laptop to my desktop using a CD (because my desktop cannot even recognize flash drives and has no internet access <---). I've backed up my laptop's driver files and put them in a folder on a CD and copied them to my desktop, however when I try to move and replace them into C:/windows/system32/drivers... I get a prompt saying I do not have permission to do so and I may try again (only to fail ofc) skip, or cancel. I have tried this on all accounts including the built in admin account and I get the same prompt, can someone help? *Edit* I just realized the action is being stopped by TrustedInstaller...is there a way to bypass this?

Software/Hardware used:

    ...is there a way to bypass this?   Yes. But it's strongly recommended not to do it by some Microsoft experts unless you really know what you're doing.   In this case, it shouldn't be necessary. Why are you copying drivers from a laptop to your desktop? Is there no possibility of locating and downloading the actual correct drivers? What is the PC that you're trying to get drivers for?   Tom

    Thx, Yes I've heard it is discouraged but my whole goal here is to install the drivers for my new wireless adapter and my mouse. I have no possible way of connecting my desktop to any network which is why i bought the adapter. I managed to find a way to take ownership from TrustedInstaller for the time being...but I still failed to get my mouse and adapter working. The PC is an HP with windows 7 and laptop is Acer with windows 7. Any idea how I can solve this issue?

    How did you get Windows 7 onto your PC? Is there no usable driver on the install medium? Personally, I'd buy a cheap network adapter card (probably available under $10-$20) and use it for basic driver download/access. It's almost certain that you're better off trying a couple fairly standard and well supported methods before altering TrustedInstaller permissions or ownership. -- Tom

    Thanks man but you seem to have misunderstood. My PC isn't brand new or anything it came with windows 7 years ago, as I said it simply hasn't had an update in years so I presume the reason it doesn't work with any USB devices other than my keyboard which the driver for had been installed on it long ago, is because the drivers are out of date. If buying and going through the hassle of installing a wireless card was an option I would have just done so. Its not hard to change properties of files/folders back after I update my drivers but it seems just copying the files into the folder isn't enough. And I don't know what u mean by install medium. I simply want my USB devices working.

    True, I didn't actually realize that Win7 was pre-installed, though that shouldn't matter. Install media either came with the PC or it's effectively already stored on your hard drive. General drivers should be available in what you have even if it was pre-installed.   Are you saying it never had networking running at all before? Is the USB network adapter recently added? Did it not come with drivers? Or is it USB itself that doesn't seem to work properly (rather than network not working)?   The PC is seven years old, and you haven't ever been able to update it? Is the mouse now not working? Or it's never worked? Or it's a recent mouse? The overall situation hasn't been clear.   Its not hard to change properties of files/folders back after I update my drivers...   For "normal" objects, that's usually true. But you're wanting to modify TrustedInstall objects. The name itself declares that it's not a component of Windows that's easy to modify. If it was, the OS would never think of it as "trusted". If it was, malware would be messing with it all the time.   If buying and going through the hassle of installing a wireless card...   I wouldn't go with wireless. I'd simply snap in a card and run a cable. Layering wireless on it is a waste.   As for the hassle, it's your PC; so it's your decision. I can only echo the strong recommendation not to do it (assuming you want a reliable system in the future).   If that's the direction you go, you might get some background from What is Package Manager?, particularly the 'Dependencies of Package Manager' section, and Supported Resource Replacement Mechanisms.   Then, check the Permission from Trusted installer thread for sample steps on obtaining permissions. The Robinson Zhang comment lists the steps. But perhaps more useful to you is the comment from ncrancher late in the thread. It links to a utility function that you might decide will be easier.   Good luck.   Tom

    I have added an additional comment, but it's likely to be morning before it gets approved to add to the thread. Not much can be done about that. Hold on. -- Tom
