Icon Cache seems to be not working in Windows 7

sfc gives you a clean bill of health.

this leaves us with:
1. some wonder program is causing the problem,
2. too many programs running in background and/or at startup time,
3. malware.

The least effort for you is to follow the procedure I give, more work for me but easy for you.

Install CCleaner:

I will do this tomorrow, sorry Have to sleep (12:03 AM in our place) for work tomorrow morning.

Have one concern though. Is the behavior of "slow painting of icons" after every restart, normal?

Oh you mean you experience the same problem as mine? I also notice the "paint delay" in my start ONCE ONLY every after restart. You say that's normal?

Yes, the paint delay is normal - it has been that way on every system and every Windows OS that I've ever used. Some are faster than others, but I don't think that I've seen 5 seconds worth. That is pretty slow.

The icon database file gets loaded onto RAM each time the OS starts. If an icon is needed, Explorer will first look in the icon database file in RAM, if the icon is not there, then Explorer has to go get the icon from the exe or dll on the hard drive or SSD. I think that these other icons are also cached in RAM for subsequent paints.

The caveat to all of the above is - this is just what I've read elsewhere. I've not dug into it myself.

I once had a similar problem...try this:

Click Start and type Regedit in the Search box and click Regedit from the list

Locate and click to select the following key in the registry:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer

On the Edit menu, click New, and then click String Value

Type Max Cached Icons for the registry key name and press Enter on the keyboard

Double-click on the Max Cached Icons registry key and type 2048 or 8192 in the Value data: box and then click OK

Close the Registry Editor

Delete IconCache.db thats located in the following path:

Windows Vista or Windows 7
%userprofile%\AppData\Local

That delay is not normal.

There is no noticeable delay on either system and let me tell you that netbook has an old atom processor.

This is what I see:


Keep in mind that this was done in a clean VM with only 512MB or RAM assigned (but assigning 256MB made it no worse). Normally I don't even that much delay, but the relatively weak host hardware was being loaded down by other VMs that i had doing things.

I have seen this type of delay on other systems too - but only the first time after a reboot. That is why I'm sticking my nose into this thread. I would like to know if increasing the icon cache size helps the OP - because I've not seen it help by a noticeable amount on other systems.

Something very much like this was suggested many posts ago.

But I'll take this opportunity to suggest using the Fix-It tool rather than messing around in the registry. If you opt to follow the link to the post and then on to the MS article, you might notice what I think is a typo under the section for doing it yourself. They tell you to create a key named MaxCachedIcons (no spaces), and then they tell you to double click on that newly created key Max Cached Icons (with spaces). This space/nospace issue has been the topic of discussion in many a thread over the years. The Fix-It tool writes a key with the spaces.

Maybe I'm just reading the MS article wrong - maybe there is no typo. I've submitted feedback suggesting that they change that... but it is still the same. And the article was recently reviewed... whatever that means

Increase Icon Cache Size

IconCache Windows 7 Ultimate x64

But let's let the OP get some sleep and then run the suggested malware scans.

Oh ok, so there's got to be something wrong with my system.

Yes but I don't understand why the need for an increase in cache file size.

This is exactly what I'm having. Thank you for that video, it explains the problem well.
