Is it possible, once vLited Vista Ultimate installed, (plus Office, updates, etc.) -- with vLite modification to remove Aero -- to somehow "put it back" into the o/s installation, without re-formatting and starting over? Now creating new .iso with 'protect Aero' checked, in case helpful, or wipe and re-install required. PC: IBM ThinkPad R51 laptop, (1830- MU1).  Centrino,  Pentium-M @ 1.7GHz + ~1,150MB Ram.  Believe Intel 855PM chipset, integrated ATI Radeon Mobility 7500 video.   MS compatibility advisor, (also AMD/ATI's), said OK for Vista, maybe minor issues XP IBM/Lenovo utilities -- (there are Vista versions).  However, all said "NO!", re. video "card",  ATI 7500.  Apparent issues: pixel shader 0.0 & vertex shader 1.1.  OK minimum RAM at 32MB (shared).   All else reported OK for Vista.   Previously: XP SP2 Pro, with IBM/Lenovo or Omega video drivers.  Worked fine, [except non-support of desired games].  Re-partitioned and formatted before Vista install. Neither IBM/Lenovo, nor Microsoft, could say whether any Vista, any configuration or features, would run at all; but, definitely not "Glass", hence removal.  High-intensity video features, e.g., 3-D translucent Aero "Glass", Flip, etc., not required; just Aero Basic appearance.  [Yes, saw posts stating = same]. ATI forum: select o/s-included driver for related 9000, which appears to work fine in present "dull" install.    Issue: laptop primarily son's.  Needed new o/s install.  Saw my PC, with full, supported Vista install, and enchanted by appearance.  He wants computer to "look like Vista", i.e., Aero Basic.  Classic -> problematically unappealing. First install -> square, gray, flat, dull look to everything.  Advanced properties has all 'glitz' boxes selected.  However, "personalize" shows only classic and other-dull options.  No Aero, anywhere.  [Otherwise, running great]. Creating .iso with vLite 1.2b, the application said OK to remove Aero, but somehow re-install/insert features or 'look' later, which forum member said faster. However, cannot find that post, nor download, that would put anything Aero back into installation.  Also, not found: some registry hack.   Possible transfer from .iso with Aero? -- (without repair re-install).  Or, is wipe and total re-install with new .iso required? Thanks!!
