Windows 7: Restore To A Previous Point In Time Question

I am running Windows 7 Professional 64 bit. The machine has been running good until a few days ago and now everything starts very slow, the screen freezes so I have to power cycle the machine to recover. I run virus, spyware and malware scans routinely. I have been told that sometimes this type of problem is caused by a "bad" Windows update which I have set to automatically run each day at 3 a.m.

If I do a system restore to a previous point in time any Windows updates will be removed (I think) back to that point in time. If a Windows update is indeed causing this issue when the machine checks for new updates again I am assuming the same "problem" update will be downloaded and re-installed.

Can I please have some thoughts on this?

Thanks!

I think you are right--if WU is responsible, then you would just be re-installing the problem.

I'd investigate the cause further--maybe you can restore to a point before the problem, and then install one update at a time--looking for the one that causes the problem to suddenly appear. If that doesn't find it, look elsewhere.

Do you have any particular reason to think Windows Update is responsible?

Thanks for your information. The only thing that has changed since this issue has started happening is the Windows update installs. My video driver is the current version.

Rather than use system restore you could try uninstalling the update that you think is the cause of the problem.

When you've done that, reconfigure Windows Updates just to let you know when they are available, and then hide the troublesome update if it is offered to you again.

Have you ran ChDsk or SFC scan now ? Check the above link and other tutorials (click tutorials at top of page)

Not very likely caused by a Windows Update, IMO.

On 12-30-11 fourteen Windows updates were installed. Tonight I did a check disk and told Windows to repair any damaged disco errors, etc. Tomorrow I will run scan disk.

This morning I ran sfc / scannow and Windows Resource Protection found corrupt files but was unable to fix some of them. I will run sfc a couple of more times.

The details of the corrupt files are in C:\Windows\Logs|CBS\CBS.log. This log file is 300 pages long if I were going to print it.

How can I tell which files are corrupt? Also, can I replace the corrupt files instead of doing a Windows 7 Repair Install?

I have been successful replacing/repairing corrupt files the one or two times I've had to attempt it.

what you could do is .system restore then having set the updates to ask first before installing then add them one by one until you find the problem update ,then once identified you can set that update to hide then install the rest and change your setting back to automatically install if this is what your preference is.

Thanks everyone for your replies. Yesterday the machine became so frozen repeatedly that I had to power cycle it to make it recover. Last night I did a clean install of Windows so today I am re-installing all of my software.
