Windows 7: How to manually install a .sys driver?

How to manually install a .sys driver?

Hello everyone.
Here's my situation: Yesterday I installed comodo firewall but accidentally did not choose custom install so i got a bunch of bloatware. I uninstalled and had to manually delete many files with comodo in its name. After doing so, I noticed that my device manager was telling me that many of my drivers were "corrupt or missing" so I looked online for help. I read that if the Wdf01000.sys file is messed up, this may occur. I followed one suggestion to try and restore the file to an earlier point but something seems to have screwed up. My computer now hangs on every boot as the windows 7 flag begins to form and restarts with no error message.

I am attempting to fix this by obtaining the same file from another computer on the same OS (Win 7 Home premium 64 bit). How do I manually install the wdf01000.sys file?

I think it's better to use win 7's own automated healing utilities, if you don't mind.

Do you have a Windows 7 install or repair disk? if not, the first two steps of this tutorial will provide clean iso you can burn to a disk, and Microsoft's own utility to make a Windows 7 installation flash drive in case you want to have one and/or the damaged computer lacks a DVD drive.

When you have the disk or usb flashdrive installer, follow this tutorial to fix corrupted system files (that are taken from the install disk, no need to pilfer them from other computers).
