Performance :: Excessively Large System Files

Jan 9, 2016

I have two excessively large system files located in C:Windows:

{2FD0AD83-973A-11E5-B6B9-ACFDCE21931D}
{2FD0AD87-973A-11E5-B6B9-ACFDCE21931D}

The first is 43.4 GB and the second is 26.6 GB. Together, they constitute 30% of my total disk usage or over 42% if you ignore my Linux VM.

Standard questions:
- What are they / what do they do?
- Why are they so big?
- Can I delete them?

I'm Running Windows 10 with a clean install originating from a late insider build. My present OS build is 10586.36. More information is available upon request.

In reply to Pinaki Mohanty's post on April 6, 2013

I tried this and it didn't work. But together with what I did next it probably worked.

Open up the folder with the pictures and click on the View tab
Next click on Options to the far right
Then Click on Change folder and search options
This opens up an options menu
Navigate to the view tab
uncheck the box that says Always show icons, never thumbnails
And Check the box that says Display file icon on thumbnails.

Disable Large Icon Over Pointer When Dragging Files?

Aug 4, 2015

I love Windows 10 but this may be the most annoying feature so far for me and I have no clue how to turn it off. I've searched online and all results concern windows 8/7/vista... and not only were there no real solutions but there is nothing about Windows 10. Never encountered this in Win7 (and never used Win8).

the problem here is I can't see where I'm dropping the files, I use the list view and manage a lot of files this damn icon hides the folders!

Apps :: How To Get Image ( Jpeg / Png ) Files From Large Desktop Icons

Oct 24, 2015

I'm trying to create some custom buttons for my PC using Rainmeter, and part of what I need is high resolution/quality icons from the programs I use. I notice that for quite a few programs, since I've set my icons to large, come up very nicely on my desktop, but I can't seem to find them of the same quality on the Internet. So, how can I take whatever file it is that creates this icon, and convert it into a high resolution jpeg or png file so I can edit it?

USB 3 ExFat Drive With Large Video Files Crash Explorer

Oct 21, 2015

I am a video director. I have numerous 1TB drives, USB 3. They are formatted with ExFAT. Files are typically large: 50Gig and better. Worked and readable fine in windows 7. Could read, write, edit with them. But not in Win10. Plug it drive, it is recognized. But once you start to click files, computer freezes. Happens in at least 2 different different Win10 computers, one upgraded, one original install. If I open an application first, like quicktime player, can see files, run them, rename them, copy them. But in Explorer: freeze/crash.

Performance :: Backup With System Image Failed Because User Files On 2nd Drive

Oct 9, 2015

I have been trying to setup a scheduled backup (Windows 7 Backup and restore) on Windows 10. I want to include a system image of the C: drive as part of the back up and save it to the D: drive. However Windows wont let me save the image on the D: drive, I think because I moved the location of my user files to the D: drive to save space on my SSD.

Any way to override or workaround this without having to move my files back to the C: drive?

Performance :: System Process Reading Disk 100% And Making System Very Slow

Dec 19, 2015

I found out that the hard disk is 100% utilized. In Task Manager, the process that utilizes the disk the most is ESET Service. If I open Resource Monitor there are many instances of the System process that are reading the disk, not writing it. I have two partitions on my disk - one for the system and the other one for data; the extensive disk reading is done for Pictures (I assigned a folder with pictures, about 140 GB in size, to the system My Pictures folder) on the data partition.

I am not running any tests in the ESET Endpoint Antivirus software and it seems to me that the high disk activity starts when I do not do anything and just e.g. browse Internet or look at something. So, it feels like Windows is doing something, but what it is and how I can influence it. If it were disk optimizations I think I should see also disk writes, not only reads. Could it be that Windows is doing something automatic with Pictures, Documents, etc.?

I wonder what is going on - I dislike the fact that something is going on with the hard disk, making is 100% utilized and making other work very slow and non-responsive.

50GB Of System Files And 4gb Of Temp Files After Installation

Jul 29, 2015

I ended up using an extra 2 GB or so of hard drive space after the windows 10 install. I ran desk cleanup and removed the old windows files which was a lot. But wasn't Windows 10 supposed to free up space?

Prior to install the computer showed 241GB of 297GB used. Now it says 256GB of 297 used. And this is after windows 10 disk cleanup removed the old OS files which was something like 20GB.

Under storage use it shows

System and Reserved - 49.7 GB inside of which 42.1 GB is system files. Isn't this a lot? The rest of the 7GB under system and reserved is 3GB Virtual Memory, 3GB System Restore and 1.5GB Hibernation file

Apps and Games - 6.83 GB (I have no games and besides the stock apps, I might have just 5 apps installed chrome,vlc player, ytd, ccleaner and iTunes

Temp files - 3.98 GB and I always kept this clean with ccleaner prior to win 10 install but been scared to run it after the update because I'm waiting on more ccleaner updates to save from issues (heard some horror stories using ccleaner on win 10)

One Drive - 51 GB used - I saved movies now this is saved in the cloud not on my hard drive right?

Background. This computer I just got a week ago. I was restored back to factory 8.0 and I than updated to 8.1 and than updated to Windows 10.

Performance :: System Restarts Itself Sometime After A Shutdown?

Jan 31, 2016

I have multiple PC's running W10 v1511. For some reason at least one of them and I suspect more than one will automatically restart after it has been shutdown. The restart does not occur immediately, in fact, it is several hours before the magic happens! The reason I know it's happening is the system will be in a sleep state when I check it in the morning after I know I shut it down the night before. The PC in question is the one that I have described in my system specs. I know all about the "Wake On" settings in the in the Intel network controller. I have them all turned off (unchecked) but that only effects the system when in sleep mode? Is there some other setting that could be causing the system to refuse to stay shutdown?

Performance :: Can't Restore From System Image

Aug 20, 2015

I created a system image on a Seagate external hard drive using Windows 10 Home, and I created a restore disc for booting with an external BUFFALO DVD drive connected to a USB port. I went into the UEFI and set my BUFFALO drive as the first drive to be used for booting at power up or reset. When I restarted the computer, a message appeared saying "Press any key to boot from CD or DVD". I pressed a key. After a few minutes, the following screen appeared:

I used the down-arrow key to select US and hit enter. Then the following screen appeared:

I used the down-arrow key to select "Choose Device" and hit enter. Then the following screen appeared:

This screen gave me only two options: (1) Boot with the BUFFALO optical drive, and (2) Boot with the Solid State Drive which the HP Spectre x360 has (instead of a real hard drive). When I used the down arrow to select the BUFFALO optical drive, the screen that asks for the desired keyboard layout reappeared. When I selected US and hit enter, the screen that asks for a booting option reappeared. When I selected "Choose Device" and hit enter, the screen that gave me the option to boot with either my BUFFALO optical drive or the Solid State Drive reappeared. I found I could keep going around in circles like this, without ever having an opportunity to restore the computer with a system image I had created earlier.

Performance :: System Very Slow To Startup?

Feb 10, 2016

windows 10 professional

This is **NOT** a boot issue, the system boots up just fine and gets to the login screen fast. The issue is the system startup after login, it is takes a rather long time for Windows to become usable. I have tried stopping all NON windows services in msconfig, but this made barely any difference. Even after the system seems to have finished the startup, once I open the browser it then takes ages until it loads the first web page. If I run task manager there is nothing that is hogging the cpu or memory or disk.

I have defragged the disk, although I had to use a 3rd party tool to do this as Windows defrag refuses to do it because it thinks it is an SSD disk due to the 32GB SSD cache.

Performance :: System And Compressed Memory

Feb 23, 2016

Is there any way to stop the "system and compressed memory" from happening? I am so annoyed by it's constant 90% Memory usage! I used to have only 8 GB of RAM and it would use 7GB out of the whole 8GB. I recently upgraded to 16GB and everything was fine. System and Compressed memory was only using 1-2GB but now it's skyrocketed up to using 90% memory (14GB). What the hell is this feature?

Edge Print Pop-up Too Large

Aug 22, 2015

When I use the Edge Print function the pop-up is too large so the PRINT "button" is partially covered by the Task Bar at the bottom of the screen. Is there a way to make the pop-up smaller. I am using a Lenovo G555 upgraded from Windows 7 to Windows 10.

Since the Task Bar at the bottom of the screen is covering the PRINT box I have moved the Task Bar to the right side of the screen. I was not able to resize the pop-up vertically so moving the Task Bar to the side allows me to access the PRINT box.

Performance :: Can't Find System Restore Points

Nov 3, 2015

I usually see the restore points created by windows but it isn't everyday backup, so I want to do a daily restore point backups, I went to Task Scheduler >> Windows>>System Restore, there is a task already there, I changed it to be daily at 4am, and It's enabled.

I check everyday in history and I see that the job is successfully done, but if I go to restore points I don't see any of those backups except the ones which Windows creates randomly or after installations.

Performance :: How To Permanently Disable System Protection

Dec 24, 2015

I use Macrium Reflect for image backup and want to permanently disable system protection. I have used the control panel to turn off system protection several times now but have noticed that for some reason periodically it gets turned back on. I have turned it off and then did a restart and it was still off but then several days later I checked and it was back on so I'm not completely sure what is triggering it to turn back on. Is there any way to turn it off so it doesn't come back on by itself?

Performance :: System And Compressed Memory Consuming 1-3GB Of RAM

Feb 10, 2016

Installed Win10 yesterday for free, everything went without a hitch that day. Today after rebooting and having installed new updates, I fire up World of Warcraft and after a minute of playing I get a freeze for 20 seconds, followed by an error message from Windows that WoW is causing memory issues.

I open up Task Manager and WoW is sitting at a happy ~1.5GB RAM usage, while another program called "System and Compressed Memory" is at 3.4GB RAM usage, after a minute it went back down to ~200MB, but kept spiking to 1-2GB

I read up on this process online, but only ever came up threads of people having issues about it consuming too much CPU, mine was sitting at 0-1% usage during that lockdown for that process.

The process is supposed to facilitate RAM usage, but so far it has only caused issues, and I never had any RAM issues on Win7. So, is there a way to shut this thing off?
