i think i may have found a possible solution to stop windows blocking\nprograms. i had tried many different ways ie, turning defender off,\nusing msconfig,etc..etc. Software Explorer did not give me the option\nto enable blocked programs within defender(greyed out) but finally\nafter several days i think i cracked it. Disable UAC (user account\ncontrol) here's how;\n\n\n\nTurning off UAC reduces the security of your computer and may expose\nyou to increased risk from malicious software. We do not recommend\nleaving UAC disabled.\n\n\nTo turn off UAC\n\n1.\n\nClick Start, and then click Control Panel.\n2.\n\nIn Control Panel, click User Accounts.\n3.\n\nIn the User Accounts window, click User Accounts.\n4.\n\nIn the User Accounts tasks window, click Turn User Account Control on\nor off.\n5.\n\nIf UAC is currently configured in Admin Approval Mode, the User Account\nControl message appears. Click Continue.\n6.\n\nClear the Use User Account Control (UAC) to help protect your computer\ncheck box, and then click OK.\n7.\n\nClick Restart Now to apply the change right away, or click Restart\nLater and close the User Accounts tasks window.\nThis worked for me, i feel in control again (until the next problem\nanyway) hope this helps some-one, it's my first post ever!
