Windows Vista SP1 - Missing acpi.sys file

Monday, April 28, 2008

Few days ago, the Vista SP1 was ready to download on Windows Update. I preferred to use my notebook as tester, before install it on my central PC. The installation completed successfully, apart the time used for it (about 45 mins). I followed the upgrade step by step, I was near my notebook all the time, working on the other PC.
