Two explorer.exe, One taking all of my RAM's Memory

I'd suggest the following:

Try downloading this patch from Microsoft:

Download MSXML 4.0 Service Pack 3 (Microsoft XML Core Services) from Official Microsoft Download Center

Get the msxml.msi download and save to your desktop then run it. Hopefully that should fix it.

As for iTunes - it's up to you. Try updating it or if you don't need it and won't lose any paid for music - uninstall it. Like I said before I know nothing about iTunes as I've always used alternatives!

That didn't go too well then. I'd assumed that installing it (MSXML 4)would take care of the update. Further research shows that MSXML 4 has been superceeded by MSXML 6 so on that basis I'd suggest uninstalling MSXML 4 then try updating MSXML 3 and MSXML 6. Sorry about that!

Also looking at your logs once more I've noticed that you have utorrent installed. Many utorrent users seem to be reporting issues with an additional memory hogging explorer process being created get after opening the containing folder in utorrent. Have you been using utorrent when you've seen the two explorer.exe problem appear?

It might be helpful if you could run another "scan and create log" with UVK when only one explorer.exe is shown in task manager. Then it might be possible to compare the two logs.

How should i do a scan and create log with only one explorer.exe shown? Usualy after ending the process it comes back like 3-5 seconds later but I could try booting into safe-mode or something else?
Also should i unstall all three MSXML 4.0 and just install MSXML 6.0? not to sure what to do here and as for uTorrent and explorer.exe problem the explorer.exe problem happens no matter what, even if i just boot the pc and dont do anything else

EDIT:
Also what settings should I use for the scan and create log? these settings or something else - Screenshot by Lightshot -

Okay so if the explorer.exe issue always happens then you can't get a scan with only one explorer.exe running.

As far as MSXML 4.0 is concerned I'd suggest removing all three that show up in the scan but leave MSXML 3 & MSXML 6 installed and try updating those.

You can run another UVK scan anyway with the following settings applied:

Since you've removed 7-zip and the issue remains - you could reinstall it but you could also consider other alternatives. Currently I use the 64bit version of Peazip. Link if you're interested:

PeaZip 64 bit | Open and extract RAR 7Z TAR ZIP ZIPX files

Thanks for the log. Winrar still shows up. The log seems to be missing lots of stuff.

It shows:

Scan mode: Hide all Microsoft files, Verify file signatures.
Scan options: Scan all users, Include MD5 hash, Include recent folders.

Would you mind doing the scan again but in the UVK scan options screen choose "None" and all the checkboxes will be cleared. Then apply the ones shown in the screenshot in this post:

Two explorer.exe, One taking all of my RAM's Memory

Ignore the "All" checkbox - just select "None" and apply the other settings. At that point don't worry if a tick appears in "All" - just run the scan. Thanks!

I'll look at your log tomorrow once you've uploaded it and report if I see any problems.

The next steps will involve some troubleshooting by doing a clean boot as shown in this tutorial:

Don't try this yet. Just have a read through it!
