I have HP Pro book 6450b 64 bit, 4GB RAM, 2.4GHZ i 5, the laptop was working perfectly until i installed the three updates from windows update feature, one was windows defender update, which i believe messed up my system.

I tried to uninstalled my antivirus Macafee enterprise 8.7 even after that the laptop takes about 20 minutes to start and then works fine. I have restored my laptop through windows 7 restore image to an earlier date but still it take around 15 min to start and it get stuck any time during the work. Specially when i go the Device manager or try to view the logs of the system it get stuck and then i have to wait for about 10 minutes.
 
I did not try to repair the system yet however i try sfc /scannow but still the result is same?

Any thoughts?

Leave MacAfeee uninstalled (or uninstall again) and then try a Windows 7 startup repair (as you suggested you might do):

http://windows.microsoft.com/en-CA/windows7/products/features/startup-repair

Be sure to back up your system first, run the repair and see if that brings a difference.

If repair and SFC (already run) do not help, it may be better in the long run to back up your system and re-install Windows 7. ... Thinkpads_User

Boot the computer in safe mode with networking ..if the computer works fine in safe mode then the problem is caused by non microsoft software that is running at startup.

Try clean boot in normal mode to find out the faulty software.

Clean boot process

Start-type - msconfig- click on startup tab- click disable all...then click services tab- put a check on hide all microsoft services ...and then click disable all....click ok and then restart the computer in normal mode.

If everything works fine in clean boot then enable five startup items and services at a time to find the faulty software.

Have you tried to scan you system for potential threats? This is the first thing you should do.

Have you looked in the Task Manager in the Performance Tab to see if there is something the eats up the CPU?

If so then locate that Exe File - if you don't know it, google it and then make you decision.

>>>  the laptop takes about 20 minutes to start and then works fine  <-- Most malware causes the machine to work slow, not fine as indicated. Also, in general, windows updates do not cause slow startup.

MacAfee may be doing a long startup scan everytime and was not fully uninstalled.  ... Thinkpads_User

I tried to repair the system but it is still the same. I have scanned the system no use. I have already disabled many software in the start up.

I will give a try with other things and see.

I have seen Windows functions take 2 or 3 minutes to get started (never 10 or 20 minutes) and the most reliable repair is a fresh install. Let us know after you have tried the other things. ... Thinkpads_User

I would recommend clean boot and safe mode ...check how things works in safe mode...if its fast then the problem is with the startup and non microsoft services.

Note that disabling startup programs wont necessarily disable their services from starting as well.

Go to Control Panel-> Programs and Features.  Uninstall any McAfee/Norton/Symantec Anti-Virus programs you have as these can typically slow your computer down.  I prefer using AVG Free as it does the job without slowing me down:

Or you can also try Avast AV:

Download either one and run a full system scan.

Next, download the CCleaner program that can clean out your temp files and unused registry keys.  I've had a lot of success with this and consistently use it on all my computers:

tayyabq8--Run System Restore to a time before you installed the suspect Windows Updates.  (Or was the image you restored an image made before the Windows Updates>)
Run Disk Cleanup. (cleanmgr.exe)
I would think Windows Defender and any antimalware program (like McAfee, AVG, Avira, etc.) would conflict with each other.  Use one or the other, not both.
