UpdateDriverForPlugAndPlayDevices Installs the driver slowly
Hi All, I used this link http://support.microsoft.com/kb/304294 as reference to install the driver. It uses UpdateDriverForPlugAndPlayDevices API to install the driver. But the problem here is it takes nearly 3-4 minutes to complete the process. Is there a way to make this fast?

Ask Microsoft to fix their extremely slow (like O(N^3)) registry snapshot.

Is there any registry snapshots? I think it is TxR, not snapshots. -- Maxim S. Shatskih Windows DDK MVP xxxxx@storagecraft.com http://www.storagecraft.com <xxxxx@broadcom.com> wrote in message news:179592@ntdev... > Ask Microsoft to fix their extremely slow (like O(N^3)) registry snapshot. > >

RE: UpdateDriverForPlugAndPlayDevices Installs the driver slowly
WHen a driver gets installed/reinstalled, registry snapshot is taken. On a system with many leftover device instances (for example, I had a couple thousand volume/DISK instances as a result of testing) it can take over 20 minutes. If you break into debugger, the registry lock is taken, and the thread that owns it is running functions appropriately named for taking a snapshot.
