Suddenly as of today, I've gotten a number of reports all at once regarding Rainmeter crashing for users of my Gadgets suite. Another user of an older version of Rainmeter posted a similar help question just now on the forums here.
The common thread among all the reporting is:
- recent Windows updates, and
- skins that use UsageMonitor and/or PerfMon plugins.
Fixing problems with UsageMonitor plugin, or here:
HOW TO: Fix your Performance Counters database.
Odd spike in performance counter corruption reports seems to have abated with the passing of Patch Tuesday.
