1) After slipstream WinXP + SP3 (RTM 5512 Czech version) and couple tweks (no remove or stop services) windows after install do not have working Windows Installer (can't install Net Framewrok, MS Ofiice etc.). I must stop and start Windows Installer again with ... 1. Unregister Windows Installer. To do this, click Start, click Run, type msiexec /unregister in the Open box, and then click OK. 2. Reregister Windows Installer. To do this, click click Start, click Run, type msiexec /regserver in the Open box, and then click OK. 2) I can't find Indexing Service in nLite Tweak Tab.
