Master tomasz86, I have questions. First, I am really thankful for your work about Windows 2000. Tis my doubtful point. After I installed 'Update Rollup 2', I checked Windows update site, there were still security update I have to do(Total 27 files). What’s strange is that few updates are already in your 'UR2' Package as far as I know. Here is the overlapped update list. ---------------------------------------------- Security Update for Windows 2000 (KB923191) ? Security Update for Windows 2000 (KB973869) ? Security Update for Windows 2000 (KB956844) ? Security Update for Windows 2000 (KB973904) ? Cumulative Security Update for ActiveX Killbits for Windows 2000 (KB980195) ? "only cat file in your UR2 log" ---------------------------------------------- Should I have to update these files? And I can still see 'UR1' in Windows update site. Second, I can't update windows after setup 'UURollup v11 week update ver.'(Error number: 0x80248008). Is this normal state? 3rd, How can I use 'UURollup' 7z(daily update) File? Thanks for your read!
