    I installed a piece of software, didn't like the way it behaved and did a system restore to earlier in the day. Windows (64-bit HPrem) hung on boot to a black screen. I re-booted into Safe Mode and I immediately got a message that said my system was successfully restored. I rebooted the PC and everything was fine, except that all my security software was disabled. I just don't know why the message of successful restoration didn't pop-up in Normal Mode.

    Before I did the system restore, should I have disabled Anti-Malware Bytes, SAntiSpyware, Avast and my firewall? I have a feeling that the security software, some of which scans on startup may have caused an issue, but I'm not certain. I did have the PC offline when I did the system restore so that there was no possibility of infection.

    I restarted all the security software and all was fine and the restore has caused no problems. Is this unusual behavior for Win7?

    Normally the system restore may fail if there is antivirus running, but, I'm thinking, since its a 64-bit system, antivirus programs are not allowed to sink any hooks into the kernel of the OS, which means that the system can successfully disable antivirus programs or anything else that may interfere otherwise, and go ahead with the SR. The subsequent blank screen on boot seems related but also self-recovered which is pretty common since Windows can restart any program or driver that was problematic or accomplish the same thing by rebooting.

    Try uninstalling the offending software prior to doing a "system restore", and check for any remnants of it after a successful restore.
    System restore has limited capabilities and is only meant to get things working again. It does not clean up after a software install has gone South.

    System restore is NOT designed to uninstall software, in fact it does not uninstall software. Use a good uninstaller such as Revo Uninstaller for that task. System restore basically restores system files to an earlier state. I would also use CCleaner to clean up leftover junk.

    You must uninstall software using the proper method. You also appear to have several security apps running at the same time. This can cause problems as well. Choose one each AV and AntiMalware app to run in real time. Also with Windows 7, the Windows firewall is much better than in previous versions, so a 3rd party firewall is not necessarily neededd. Reserve all other AM apps to periodic scans, but do not let them run in the background.

    Once you get everything back to where it was, use an imaging app to image your OS partition so that if things get hosed again, a simple restore using the image is much quicker.

    Technically true but effectively it does uninstall since all hooks lead to/from the registry are gone once an earlier copy replaces the current and that is what is important when it comes to the Windows OS. It is not neat and tidy though of course to rely on SR as the sole method of program removal, but in conjunction with a normal uninstall, provided the system remains viable for such activity, it's fine.

    Perhaps all hooks to the OS would be removed, but since SR does not remove all traces of an app, there will be leftovers which as we all know are not something we want left in our systems.

    Yes SR in conjuction with a normal uninstall would work, but only if the normal uninstall was performed before the SR. That's the real reason that a complete uninstall of an app should be done.

    SR is a poor alternative to a system image. It may solve a problem, or may not solve a problem. It may help a system to be more stable but I have read just as frequently that SR has not helped. That's the biggest argument for a good image on a regular basis.

    Sorry to have gotten slightly off topic. In the original question, an uninstall, followed by disabling security S/W, followed by a system restore may have helped in this situation, but several different security S/W apps all running can cause more problems than they solve.

    I find it strange that nobody mentioned the " Programmes & Features " in the Control Panel. That is the way to remove an unwanted programme.

    The use of "Programs & Features" in the control panel is one of the first methods to use when uninstalling a program.
    If this doesn't work, then the use of the programs own uninstaller should be tried. After these attempts have failed,
    a third party app like Revo can be tried. Finally, it can also be done manually by removing registry entries and deleting
    the physical-location folders and items.

    See Fred Langa's latest article on "Use Windows System Restore with caution ".

    When I say an app should be uninstalled appropriately, I use Revo Uninstaller. It uses the normal Windows Uninstaller for the initial uninstall (or the apps uninstaller if there is one) then further hunts for leftovers to uninstall them. I guess I wrongly assumed that my readers would understand that the normal Windows Uninstaller was found in Programs and Features. Sorry for the oversight on my part, and yes you are correct, the normal Windows uninstaller is located in the Control Panel, Programs and Features. Thanks for reminding me to be a little more complete in my answers. Not everyone knows where to look for these features.

    Its not an alternative. SR is like carrying the six shooter around to shoot varmits, snakes and the occasional stagecoach robber. System image is like the shotgun, for when things get serious. Any attempts to equate the two are misguided at best but also any attempts to disjoin the strengths of each in conjunction is equally misguided.

    would understand that the normal Windows Uninstaller was found in Programs and Features. Sorry for the oversight on my part
    Mea culpa as well.

    I think I wasn't clear in my original post. I didn't use system restore to remove the offending software....I did uninstall properly from within Windows and used CCleaner after to remove any droppings. I then did a restore to earlier in the day

    I wasn't prepared for the black screen at bootup after doing the system restore. I got the "system was restored successfully" as soon as I booted into Safe Mode. All was well and system operated normally except all my security software was disabled which was no big deal, but I never had that happen before. I did take myself offline when I do this stuff so there was no issue with security. But for future reference, is it a good idea to to temporarily halt things like AVAST, SAS, firewalls when you so a system restore. All these programs do scan on startup and perhaps all of them running at once on reboot caused this behavior.

    Thanks.

    My Apologies.
    All these programs do scan on startup and perhaps all of them running at once on reboot caused this behavior.
    Perhaps the combinations in the above programs did cause the crash.
    Taking yourself offline during all this was a good precaution and it can't hurt to disable some of your more intrusive
    startup applications prior to a system restore in the future.

    My apologies as well. I also thought from your original post that an uninstall was not done. I also suspect the security software, which under normal conditions are vital, caused an unexpected problem. Glad it's all back to normal.

    Ted, good morning to you.

    " When I say an app should be uninstalled appropriately, I use Revo Uninstaller. It uses the normal Windows Uninstaller for the initial uninstall ".

    From W 3.1, I always assumed that the machine knows better than I so I always followed the proper procedure as explained in Help. ( ??? ) It definitely said that Add/Remove is the way to go. Now, thanks, I have learned that the Revo uses the Uninstaller, a nicer way to go.

    I always went to Regedit after the Add/Remove and found slews of leftovers. This gave me the false impression that I was really the Master of the machine. Ha ! JP.

    This is my procedure to uninstall software:
    1) Revo Uninstaller;
    2) CCleaner

    ~and~ if the software could have really sunk its hooks in everything
    3) After a reboot, System Restore.

    I have not had to resort to #3 yet, but you n-e-v-e-r k-n-o-w...

    Take care!
