Downloading the boot image with TFTP is slow and download may fail within slow or unreliable networks.
Downloading with HTTP or iSCSI will increase the speed dramatically and the stability is improved also.
With iPXE this technology is implemented and works fine.
My idea is to implement the HTTP download with SCCM.
This would be a great enhancement to performance and stability in the OS deployment.

It is possible to "Install Application" in a Tasksequence. It would be nice to be able to "Uninstall Application" too.

Allow custom icons for Task Sequences and Packages/Programs in Software Center.

Currently the icons are all a default icon, which can be confusing for end users if there are multiple deployed to a workstation.

With a standalone WSUS-Server deployed Windows Updates can be uninstalled/removed from clients. With SCCM SUP this is not possible,
Implement a function to remove installed Windows Updates from clients.

It would be really great if when configuring an Automated Deployment Rule you could configure it to run based on the number of days / weeks since "patch Tuesday" (especially in countries other than the USA where "patch Tuesday" is actually a Wednesday and not necessarily the second Wednesday of each month). I currently get around this by having a script detect when patch Tuesday has passed and subsequently execute an ADR and create one or more deployments based on the number of weeks since that date. This works fine, but an in product solution would be better

Basically would like something similar to the Windows Updates Reboot/Postpone nag prompt except with the ability to customize the notification text as applicable to the deployment.

For example:, as a sub-setting of the deployment type for the application you have the option to enable the reboot/postpone prompt and customize the notification text of the dialog box.

If the user that receives the prompt, postpones they will be re-prompted at the end of the postponement period until they either reboot or shutdown the system. (basically exactly the same behavior as the Windows Updates reboot/postpone prompt).

Many places like to give users custom UIs when an application is being installed. It would be nice to be able to prompt the user for input or give them information without losing the ability to add that application to a task sequence.

Support SUP/ESD/WSUS/update-based packages via the "Upgrade Operating System" task sequence step so that task sequence-driven upgrades can benefit from the smaller size of the ESD files (2.5GB) compared to the full media used today (3.5GB).

The ability to multi-select applications to be installed via the Software Center, so as to create an installation queue.

Instead of having us integrate MDT, why not just include the scripts in a new SCCM install by default?

In the new Software Center the icons in the catalog are blurry. I have attempted to upload new ICO's with better quality, but the results remain the same. Please consider resolving the quality issue and/or allowing larger icon resolutions above 250x250. The new Software Center is nice, but only if we make it that way with professional icons.

Configuration Manager should be able to configure all aspects of a workstation that can be done using other Microsoft tools. Some group policy items already exist such as folder redirection and Firewall Policies. It would be great if Firewall could be expanded to include creation of firewall exceptions. It would also be great if we could configure all group policies from within SCCM perhaps using compliance settings.

As more and more devices are shipping without wired network adapters, and more business areas are going "wireless only," the traditional ability to reimage a device in place is getting scarce. This is especially true in primary and secondary education institutions.

Please provide support for adding Wireless drivers to WinPE, and the ability to provision wireless network profiles for the WinPE phase of the task sequence to enable imaging over wireless network connections.

Enable easier integration with partner products or have the ability to pull down 3rd party catalogs.

Would be nice if the application approval request feature had built-in support for emailing.

It's time

Add an column to the devices view that would display Active Directory descriptions in console.
