@tomasz86, I have already read the topic on your first link and have been on your website many times. This is the order that I installed the updates (I already had the original SP4 installed): W2K Update Rollup-KB891861-v2.EXE (First rollup of updates and additions since SP4.) The MS$ file name may not be exact, but it is the official one. Your Update Rollup2 (I may not have the exact file name: Windows2000-UpdateRollup2-x86) Windows2000-UURollup-v10d-x86-ENU.exe (which "updated" my W2K to be able to run certain apps, such as the newer Firefox/SeaMonkey) I have tried my hardest to find your download link for UURollup-v11and Google does not have any download sites. I know you have SkyDrive, but I am unable to see anything on it as of yet a search for "tomasz86" or "UURollup-v11" brings no results. I tried DropBox and can't seem to find you there either. A link to these latest updates would be helpful. I have a dual-drive setup and tested your UURollup-v10d-x86 extensively with good results, except for an icon problem which I fixed (some of the file associations disappeared, along with the icons!) I just put them back in the registry and did a "restore" in Folder Options/File Types. If v11 of the UURollup allows me to run Macrium Reflect Free, that would be great. There was one other issue, which isn't critical to me, but is annoying: since I installed the UURollup-v10d, all of my scheduled tasks will not run. I went in to each one and reentered my logon/password combination (I run as Administrator with full rights.) Nonetheless, they will not run. I have a scheduled Microsoft Backup which used to work, but now, when I manually run it, I get errors in my log file, "You do not have permission to access portions of [folder name]. Please see the owner or administrator to get permission" for EACH folder that I have selected to be backed up. I have FULL permissions. I have tried various tricks, to no avail. There is no help online for this problem. The .BKF file that Microsoft Backup creates is not usable and will not restore files. Any suggestions? One more thing: on your website, "http://windows2000.tk/#archive" you mention the Application Compatibility Launcher and mention running the Firefox install. I used your link in MozillaZine instead: http://forums.mozillazine.org/viewtopic.php?f=23&t=2482475 with great results. I am running SeaMonkey 2.16 (Firefox 19 platform) with no problems whatsoever. Thanks for your prompt reply to my posts. GaryMX
