Here r some questions i'm having after installing sp2. 1. It is said that Zone alarm does not run properly in sp2 (digit sept 04). I tried installing it from the digit cd. it got installed from the july cd.its working alright. how come? 2.i installed tweak xp pro. its a trial version. so once it expires will all the settings revert back. also i installed system mechanic. its also trial version.is there any free software similar to tweak xp? 3. in the May 04 digit, where ice's tips on improving os performance was given. he recommended installing zoom. can anyone give me the link to download it. any user who has experienced its working plz give ur suggestion. 4. There is always a difference in the free memory shown by AIDA and tweak xp.why? for memory optimisation in tweak xp to work it should be always running. that means load on the system and long boot up time. is there any other way ? any other memory optimiser only software. plz suggest. is 256 MB ram less. 5. which firewall is more lighter and effective. zone alarm or sygate ? 6. There are some entries in my "add remove programs" list which do not work. i mean there is f-16 demo which doesnt get uninstalled ( shows " d:\programfiles..........demo\unistall.isu is not valid or corrupted). then there is tribes ( game) the folder of which got deleted by mistake. any solution? 7. similarily in the msconfig box there r many entries of software which i have already uninstalled. i remember there is a way to clear them out by editing autoexe or smthng. plz give the procedure. there is also an entry 8o> revert settings. i have unchecked it. what is it.? 8. is there any way to stop the security control centre from appearing in the system tray? plz do reply. soory for the long post.
