when ever the computer starts a system properties dialogue box apperrs saying that"windows created temporary paging file on your computer because of a problem that occured with your paging file configuration when you be somewhat larger than the size you specified" and when we click ok there appers another table PERFORMACE OPTION,what should i do inorder to prevent this
It seems that you have specified a paging file size that is rather too small. On the Performance Options page that pops choose the Advanced tab, then click Change on the Virtual Memory section; in the new Window set a Custom size, as a guess 1000MB min and 1500MB max, Set and OK your way out.
If you indeed found stuff using msconfig that you considered unnecessary, make sure to reallow it and then uninstall it correctly. Do not uninstall/remove while it is unchecked in msconfig else not all features will uninstall.
