Fixing Windows 8.1 blank start menu

Some older programs not updated to work correctly with Windows 8/8.1 will produce some very undesirable results when uninstalling them, such as clearing out your start and app screens.

Echolink is one program that affects Windows 8 in this way when using its bundled uninstaller. You can read about how to extract the exe to run it as a standalone program in this post.

You can see below a sample of an affected system, and that all the tiles have been removed from the start screen and all apps screen:

EL_UnInst_Start_1EL_UnInst_Start_2

In this situation, the search from the start screen is available, but will not produce any results. The only way to navigate is to right-click on the start button and make selections from that menu, or to use the charms bar.

Various sites offer various fixes for this issue, and I haven’t found one that works without either refreshing the PC or having to use a restore point. If you use a restore point to recover, the program will likely be reinstalled. If you refresh your PC, you will keep your data but you may lose some settings or customizations.

For either of these two methods, follow the link below:

I wish I could find a consistent fix without having to use the above, but they methods do work.

If you have a solution that works, please feel free to share it in the comments below. Thank you!

ACL fix for Synology DiskStations

A reader got in touch with me regarding my previous post, Quick sh script cronjob to fix user homes permissions on Synology. That script was initially intended to fix user homes file ownership, but this reader shared a script that uses the synoacltool to fix the Access Control List on directories.

A few thoughts regarding this script:

First, it was mentioned that these issues may be fixed in the latest DSM release. If you’re still experiencing file ownership and permissions issues, please feel free to use the solution linked to above or posted below.

Second, the script linked to above and the script below take different approaches on the problem. You may find a solution in one, or you may elect to use both.

Third, it was mentioned that this was a “one and done” solution. Due to the changing nature of filesystem content, I don’t believe that to be the case. You may want to save this as a sh script and run it as a scheduled task, or you may want it to run on every boot up. If you decide you want to run it on every boot, edit (or create) the file /etc/rc.local, and paste the below. I can’t say for certain whether this script is preserved on an upgrade, though this page strongly suggests that it would be preserved.

I don’t have a Synology unit right now to test this on, so I can’t offer any insight other than what I’ve shared above.

Here’s the script:

#!/bin/sh
synouser --enum all > user.list
sed -i 's/\\/\\\\/g' user.list
cat user.list | while read line
do
echo -n "$line: "
USERDIR=`synouser --get "$line" | grep "User Dir"`
if [ $? != 0 ]; then
echo "user: [$line] not found"
continue
fi
HOMEPATH=`echo "$USERDIR" | cut -d'[' -f2 | cut -d']' -f1`
synoacltool -get-archive "$HOMEPATH" | grep is_support_ACL > /dev/null 2>&1
if [ $? != 0 ]; then
echo "[$HOMEPATH] not support ACL or not exist"
continue
fi
synoacltool -get "$HOMEPATH" | grep -F "user:$line:allow:rwxpdDaARWcCo:fd--" > /dev/null 2>&1
if [ $? = 0 ]; then
echo "[$HOMEPATH] exist user's Full Control ACL"
continue
fi
synoacltool -add "$HOMEPATH" "user:$line:allow:rwxpdDaARWcCo:fd--"
done
rm user.list

Any feedback is welcome and appreciated. Thank you!
