These are the Additions on SoLoR's list that are integrateable directly in RT7 (or, if you extract the CAB's from the .MSU's with 7Zip, in DXIntegrator or DISM/WSIM):
-- MS Help
-- Win File Mgt. API
-- System Update Readiness Tool
-- Virtual PC + Hotfixes (but
not the XP Mode .EXE installer)
-- MS Agent
-- WAT
-- Win Identity Foundation + Hotfixes
-- Browser Ballot
-- IE9
These are listed on SoLoR's updates changelog in
red text. The KB numbers all match up to the downloads in the Additions folder.
These Additions are only available as the MS-download .EXE installers in the Additions folder and are not listed on SoLoR's changelog:
-- Bing Bar
-- DirectX Runtimes
-- .NET 4 Client or Extended, x86 or x64
-- Windows Live Games
-- XP Mode
-- Silverlight
-- MS Security Essentials (navigate up to the parent folder on the site to grab that)
SoLoR only provides these as-is from the MS downloads site to put the very latest versions in one place. They aren't switchless installers; you would have to manually make those to integrate in RT7 or DXIntegrator (DXIntegrator requiring an entries.ini file). n0ak has a switchless for .NET x64 here on the forums, and there are plenty of others posted for x86. Yumeyao has a switchless here for DirectX (x86 or x64). If you use DXIntegrator you can use OnePiece's true addon .NET (x86 only) and Silverlight addons and get a cleaner integration than a switchless.
Note that XP Mode can't run in a VM, only a live install. So I don't know what its silent switches are for making a switchless installer.
There's also a switchless
here for Windows Live Essentials (page is in Italian, with the d/l link at the top). It's already got the DXI entries.ini so can integrate it as-is in DXIntegrator. Or you can extract the switchless .EXE and integrate in RT7.
Except for MS Update (which nobody's yet done a Win7 switchless or addon for), pretty much all of the MS additions are available in some form for an integration, although obviously for several of them you've got to d/l one of the available switchless installers here on the forums.
