Windows 7: Checking For Updates, taking forever w/ svchost.exe, high memory usage

Checking For Updates, taking forever w/ svchost.exe, high memory usage

I'm currently seeking help regarding the checking of updates on my computer.

Checking for updates is already taking hours.

It's been over a year since I have updated my computer. I decided to update it today as to make good use of the free time from work and to get the Windows 10 Upgrade notification before its too late.

Windows Updates states:
Most recent check for updates: March 9, 2014 at 9:01AM
Updates were installed at: March 9, 2014 at 8:44AM

BUT, when I checked my update history, the last installed update was the Windows Update Agent 7.6.7600.320 installed at July 17, 2015(The date I posted this thread). It seems like it installed when I shut down my pc and restarted it.

Also, the svchost.exe process connected to the Windows Update is taking a huge (approx.) 700,000k from my memory and memory usage is at 90%(Only have 2gig ram with only 1.85gig available.) And upon checking for updates, there also appeared a TrustedInstaller.exe process.


Any solutions?

TrustedInstaller always runs when checking for updates - it's the main engine for installing them, and is used to check the integrity of partially-downloaded updates.
(Yes, there are many valid reasons for turning off updates! )
Installing the Update Agent resets the WU system to a large extent, and Windows Update has to start again from scratch - the first scan always takes a long time as it rebuilds the database. In a system with limited RAM, this can indeed require a very long time! 2GB is bare minimum for an x64 install - you'd really be much better off using a 32-bit OS in that amount of RAM.

Please follow the Windows Update Posting Instructions and post the requested data

If the file is too large (8MB compressed), remove the older CBSPersist cab files until the final file is below the limit - you can always post them separately after zipping them. (the forum doesn't allow the upload of bare CAB files, for a number of reasons)

Please also post the C:\Windows\windowsudpate.log file

Make a fully update in Windows Update and it will fix it, that memory usage appears when you search for updates and it will appear every time until you do it. Try it.

Thank you for reply! It seems like 30 minutes after posting this, it finished checking for updates after a grueling 6+ hours.

But you may be right that it might have been because of the minimal ram on my laptop despite it being the bare minimum for a 64bit pc. I just realized now that an additional cause may have been my internet speed which is just 1mbps(standard internet speed in the Philippines, yet one of the most expensive).

Again, thank you for your reply and I'm sure your advice would also be helpful in the future. Also, please forgive me for not following the posting procedure. I never saw it until now. :)

Thank you for solving my problem! :)
